EXECUTIVE SUMMARY

This report covers three types of mineral industry operations in Illinois (fig. 1):

extracting minerals from the ground

processing crude minerals (mined primarily out of state) into raw industrial materials

manufacturing mineral products such as coke, lime, and cement from minerals extracted and processed primarily, but not exclusively, in Illinois.

1992 Reported Value

The total reported value of minerals extracted, processed, and manufactured in Illinois during 1992 was $2,894.3 million, 0.5% lower than the 1991 total. The total of the values reported to the U.S. Bureau of Mines (USBM) is not necessarily the actual value because many producers do not report their production figures. Minerals extracted accounted for 90% of the reported value; processed crude minerals and manufactured minerals accounted for the remaining 10%. Coal continued to lead in value, followed by industrial and construction materials and oil (table 1, p. 23).

Illinois produced 6% of the tonnage and contributed about 8% of the value of coal produced nationally. The state continued to lead the nation in production of fluorspar, industrial sand, and tripoli. Production of stone was 6.3% and sand and gravel, 4.2% of the national total (table 2). Illinois ranked sixteenth in the value of nonfuel minerals produced in the United States in 1992.

Extracted Minerals

In 1992, the value of commodities mined in Illinois was $2,607.6 million, a decrease of 4.4% from the 1991 total. Mineral fuels (coal, crude oil, natural gas) accounted for 78.2% of the total; coal alone accounted for 64% of the total. Industrial and construction materials such as clay, fluorspar, sand and gravel, stone, and tripoli accounted for 21.4%. The remaining 0.4% was contributed by metals such as lead, zinc, and silver, and minerals such as peat and gemstones.

Mineral extraction was reported from 98 of the102 counties in Illinois (table 3, fig. 1). Only Cass, Mercer, Pope, and Stark Counties had no reported mineral extraction. Perry, Franklin and Saline Counties, major producers of coal and crude oil, accounted for more than one-quarter of the state's total value of minerals produced: 1 1 .3%, 8.5% and 8.2%, respectively.

Processed Minerals

Data for total value of processed minerals in 1992 are incomplete.The total includes only the figures for ground barite, expanded perlite, sulfur, calcined gypsum, exfoliated vermiculite, iron- oxide pigments, and slag. Minerals not listed (tables 1 and 3), but processed in the state, are natural gas liquids, bismuth, and primary and secondary slab zinc.

Manufactured Mineral Products

Mineral products manufactured in Illinois, primarily from minerals mined within the state, include cement (portland and masonry), coke, clay products, lime, and glass. The average unit value of sales of portland cement increased about 1.0%; no 1992 data are available for masonry cement. Lime production and its value was up 0.4%. Clay products increased 3.9% in value. Data are no longer available for coke or glass.

Employment

The Illinois Department of Labor reports that jobs in mining, quarrying, and oil and gas extrac- tion continued to trend downward, decreasing 9.9% from 19,200 employees in 1991 to 17,300 in 1992. Total nonagricultural employment went up 0.3% from 5,220,100 employees in 1991 to 5,234,900 in 1992. Employment in the goods-producing sector decreased 4.7% from 1,165,100 employees in 1991 to 1,133,500 in 1992, and in the service-producing sector, increased 1.1% from 4,055,100 employees in 1991 to 4,101,400 in 1992 (table 4). The Illinois Department of Mines and Minerals reported in the Annual Coal, Oil and Gas Report, 1992 that employment in the Illinois coal industry decreased 7.6% from 9,667 in 1991 to 8,932 in 1992 (table 9).

Mineral Shipments

Mineral shipments are a large part of the Illinois transportation industry. Stone, sand and gravel are usually shipped by truck because they are primarily used near their sources. Coal is largely shipped by rail, barge, or rail/barge combination; only about 4% of the coal was moved to mine- mouth electricity-generating plants by conveyor belt. Crude oil and natural gas are mainly trans- ported by pipeline. Other materials, such as fluorspar and clay products, are shipped by rail, truck, and barge. Pig iron and coke are generally used on-site by integrated mills.

Consumption

In 1992, the value of the state's consumption of mineral commodities was about 4.5% to 5% of the nation's total, or about the same proportion as Illinois' share of the total U.S. population. In physical units, Illinois' mineral consumption varied from less than 1% of the U.S. total (for resid- ual fuel oil) to almost 15% (for zinc) (table 5). The high zinc consumption reflects Illinois' status as a major manufacturing state.

The state's energy consumption was estimated to be 3.3 quadrillion Btu in 1992 (4.1% of the U.S. total), 1.5% less than it was in 1991 (table 6). Fossil fuels provided 76.4% of the state's energy needs: 26.2% was provided by oil and oil products, 30.1% by natural gas, and

Coal

Production In 1992, Illinois continued to rank fifth in production, behind Wyoming, West Virgin- ia, Kentucky, and Pennsylvania. Illinois coal production increased less than 1% from 60.0 mil- lion tons in 1991 to 60.3 million tons in I992 (table 7). Total value was $1,668.8 million, based on a unit value of $27.66 per ton, a 2.4% decrease in per ton value from 1991 (table 1).

In 1992, coal was produced in 17 counties (fig. 3), as compared with 18 counties in 1991. Douglas County's only coal mine, Zeigler Coal Company's Murdock Mine, closed September 1991. Perry, Franklin, Saline, and Randolph Counties together accounted for 53.1% of the state's production. Perry County remained the top producer, contributing 17.6% of all coal produced in the state.

Approximately 79% of the state's total production came from underground and 21% from surface mines; whereas 5 years ago, 67% came from underground and 33% from surface mines (fig. 4). Production from surface mines has been declining since 1980. Approximately 76% of Perry County's output came from surface mines a significant percentage that repre- sented about 63% of the state's output of surface-mined coal. Franklin County, producing solely from underground mines, contributed more than 16% of the total underground production. In Saline County, about 93% of its coal was produced from underground mines output that contributed more than 15% of the state's total underground production. More than 87% of Randolph County's coal came from underground mines and accounted for about 12% of the state's total underground mined production. Other counties contributing substantially (more than 3 million tons each) to underground coal mine production were Jefferson (9.4%), Macoupin (8.9%), Gallatin (6.5%), and Clinton (6.5%) (table 7).

The number of coal mines operating in Illinois has steadily declined since the early 1900s. There were 920 mines in 1900. By the 1950s, approximately 200 mines were in operation. A further rapid decline to about 60 mines had occurred by 1970. In the latter half of the 1970s, the number of mines increased to about 70 as new mines opened after the first oil-price shock of 1974. Demand for coal did not increase, however, and the number of mines dropped again.

By 1992, 39 mines remained in operation: 27 underground and 12 surface mines (fig. 5). The number of surface mines, like production from surface mines, has been steadily declining. In 1988, there were 27 underground mines and 16 surface mines.

Since 1833, Illinois mines have produced more than 5.57 billion tons of coal (table 8). Sur- face mines operating since 1911 account for 1.32 billion tons or 23.7% of the total production. The peak year for surface mining was 1967 when production reached 37.2 million tons, where- as underground mining hit a high in 1918 with 89.5 million tons.

The average output per underground mine reached a new peak of 1.76 million tons in 1992 after dropping 8% in 1991. The average surface-mine output increased about 1% in 1992; however, output per mine has been decreasing after reaching a high of 1 .31 million tons in 1989 (table 9).

The trend in Illinois is toward fewer but larger coal companies. Of the 21 coal mining com- panies operating in Illinois in 1992, the top five companies— Old Ben (Zeigler), Peabody, Con- solidation, Monterey, and AMAX contributed about 59% of the state's total output (table 10). For comparison, the top five U.S. companies produced 26.1% of the national total in 1992. Pea- body, Consolidation, AMAX, and Old Ben (Zeigler) are four of the top five U.S. companies.

Employment and wages In 1992, employment in Illinois coal mines declined 7.6% to 8,932 employees (table 9). Employment has declined about 51.3% from the 1981 level of 18,148 coal mine employees. The decrease was 4.5% in underground mines and 21% in surface mines.

Mine productivity Productivity is measured in tons per shift per miner and calculated by multi- plying average production per miner per hour by average length of a miner's shift. Unrounded data are used in calculating the changes in percentages. The labor productivity of underground mining operations increased 12% to 26.9 tons per shift per miner in 1992 a 17.3% increase

over the previous high of 22.9 tons in 1969. In surface mines, labor productivity in 1992 increased 5.5% to 36.3 tons per shift per miner. The peak year was 1967 with 41.6 tons (fig. 6). The productivity of Illinois' surface coal mines continues to fall farther behind the U.S. average.

Prices The average price (f.o.b. mine) of Illinois coal decreased 2.4% to $27.66 per ton in 1992 (table 7). Coal mined underground in Illinois averaged $27.93 per ton, down 3.9% from the 1991 price, and surface-mined coal was $26.69 per ton, up 0.4% from the 1991 price.

Shipments Illinois coal was used in 18 states to generate electricity, manufacture coke, and supply energy for other industries. In 1992, about 90% of Illinois coal was sold to electric utility plants, about 1.0% to plants manufacturing metallurgical coke, and 7.7% to industrial plants and retail dealers. Illinois' coal exports to foreign countries dropped to 1.25 million tons in 1992 from 1.27 million tons in 1991 (table 11). Shipments to electric utilities increased slightly from 52.5 million tons in 1991 to 52.6 million tons in 1992. Only 28.4% of shipments went to utilities in the state. Out-of-state shipments to utilities increased 4%; 29% of the out-of-state shipments went to Missouri, 28% to Georgia and Florida, and 24% to Indiana. All Illinois coal used for making coke was used in coking plants in northwestern Indiana. Of the Illinois coal used for other industrial activities, 71% was consumed in the state, and about 14% was shipped to Missouri, 7% to Wisconsin, 3% to Indiana, and the remaining 5% to other states.

Transportation Coal was shipped from mines to the consumer by rail, barge, and truck. Barge or rail/barge combination has been gaining importance in Illinois as transportation costs become an important aspect of price competition. Use of Illinois coal depends primarily on out-of-state markets and transportation costs must be kept low to compete with other coals.

Consumption Illinois ranked seventh in coal consumption in 1992 after being fifth in 1991. Con- sumption decreased 5.6% to 31.2 million tons in 1992 (table 12). Coal shipments from Illinois mines to Illinois markets have declined steadily since the late 1960s. In 1990 and 1991, how- ever, consumption increased in the state; then in 1992, consumption declined more than 3%, back to the 1989 level. As figure 7 shows, coal imports from western states are increasing, primarily because of the impact of the Clean Air Act on markets for high-sulfur coal. In 1968, more than 82% of all coal consumed in state was also produced in state, as compared with 58% of coal produced and consumed in Illinois in 1992. Total coal consumption by electric utilities in Illinois has fallen each year, and 1992 was no exception as consumption fell 5%. Declines are the result of the increasing use of nuclear energy. Coking-coal consumption increased 6.5% in 1992; however, all coal used came from out-of-state, 99% from Appalachian states and 1% from western states. Industrial consumption, 81% of it in-state, still showed a decrease of about 1 5%.

Crude Oil

Production Crude oil production in Illinois increased 0.4% after decreasing 37% during the previous 6 years. Crude oil production in Illinois supplied only about 9% of the petroleum prod- ucts needed in the state in 1992. Other states and foreign countries supplied the rest. The 1992 production of 19.1 million barrels of oil had a value of $368.6 million, with an average unit value of $19.26 per barrel. This represents a 4.6% decrease in per-barrel value from that 1991 (table 1). Secondary production by waterflooding accounted for approximately 7.85 million barrels or

about 41% of the state's total. Pressure-maintenance operations produced an estimated 995,000 barrels or 5.2% of the state's total (fig. 8). About 3.44 billion barrels of oil has been produced in Illinois during the past 104 years (table 13).

Illinois ranked 13th of 31 oil-producing states in 1992. Forty-six counties produced crude oil (fig. 9, table 13). The following five counties produced more than 1 million barrels each, contributing about 46.5% of the state's total oil production.

An oil field producing more than 200,000 barrels per year is considered a major field in Illinois. In 1991 and 1992, there were 12 major fields, which together produced 55.7% of the state's total in 1992 (table 14). The two largest fields, Lawrence and Clay City Consolidated, each produced 2 million barrels or more during 1992 or 23.7% of the state's total. In 1992, there were 42 new wells with reported initial production of 100 or more barrels of oil per well per day. The highest initial production reported during the year was 816 barrels of oil per day for a well located in a field in White County. The average daily per-well production in Illinois is 1.65 barrels, so the state remains highly sensitive to oil price changes.

Crude oil production reached a peak of 147.6 million barrels in 1940 (fig. 8). From that level, oil produced by primary recovery methods declined steadily until 1973, although some years showed small gains. The introduction of the hydraulic rock-fracturing method in 1954 and the increased use of waterflooding stabilized oil production at about 78 million barrels per year from 1955 to 1962. Production fell steadily after 1962 as reserves were depleted. In 1989, production dropped to 20.3 million barrels, the lowest since 1937 when production was just 7.4 million barrels. It continued to drop in 1990 to 20.0 million barrels and in 1991 to 19.07 million barrels, but in 1992, it rose to 19.14 million barrels.

By December 1992, proved reserves were 138 million barrels, a 7.8% increase from that of December 1991. Current reserves are 80.3% below the 700 million barrels of reserves of January 1956, the post-World War II peak.

Refineries As of January 1993, Illinois had seven refineries operating in Cook, Crawford, Lawrence, Madison, and Will Counties. Total refining capacity was 965,600 barrels of oil per day, up 1.4% from January 1, 1992. Illinois' annual refining capacity far exceeds its total consumption of petroleum products and makes the state a net exporter of petroleum products. Low oil prices, although detrimental to crude oil producers, can work to the advantage of the refining industry and the state's economy.

Consumption Reported consumption of major petroleum products in Illinois increased 2.6% in 1992 because of an increase in motor gasoline, lubricants, and asphalt and road oil. The use of residual fuel oil, liquified gases, and kerosene declined (table 15).

Figure 10 Consumption of natural gas in Illinois, 1955-1992.

Natural Gas

Production Natural gas is not produced in large quantities in Illinois, therefore the state is almost totally dependent on other sources for its needs. In 1992, the state's reported production of natural gas decreased 26% (table 16). Although production has been slowly declining for several years, in the last 3 years it dropped 77%, primarily due to several depleted or idled gas fields such as the Pittsburg field in Williamson County. There was no production in Williamson County in 1992, although it was the top producer in 1991. St. Clair County, with 27% of the state's total output, was the top producer in 1992. Gallatin County with 24% was second and Saline County, also with 24%, was third (table 17). The average wellhead value of Illinois gas decreased less than 1% from $2.17 per thousand cubic feet (Mcf) in 1991 to $2.15 per Mcf in 1992 (table 1).

Consumption Natural gas consumption in Illinois began to decline after 1971 and reached a recent low in 1987. Since then, consumption has been generally rising in Illinois (fig. 10). Reported consumption of natural gas decreased 0.5% in 1992 (table 18). Although the largest percentage of decrease (28%) was for electric utilities, it represented only a small volume of gas. Industrial and commercial usage increased slightly (0.2% and 0.3%, respectively). There were small decreases in consumption in the residential (1.8%) and other sectors (6.8%).

Industrial and Construction Materials Primary Barite

An accessory mineral in fluorspar ore, barite, is recovered as a byproduct by the fluorspar industry of Hardin County. Ozark-Mahoning, the only producer in Illinois, continues to turn out barite at its Rosiclare mill. Because of the small scale of the barite operation, the increases shown in 1992 were 94% in production and 61% in value. Barite is used primarily as a weighting agent in mud systems for drilling for oil and gas. Other uses include the manufacture of paints, rubber, glass, and barium chemicals.

Clays

Production Shale, absorbent clay (fuller's earth), and common clay are mined in Illinois. A partly consolidated bedrock clay is mined in southernmost Illinois to produce absorbent clay products. Fuller's earth is also an absorbent clay or clay-like material that decolorizes and puri- fies. In Illinois, deposits of unconsolidated surficial clays and consolidated bedrock clays and

shales are mined to produce common clay. Common clay is defined as a clay or clay-like material that is sufficiently plastic to permit ready molding. The USBM reported Illinois clay production (excluding fuller's earth) increased 4.1% from 566,741 tons in 1991 to 590,047 tons in 1992 (fig. 11). Nationally, Illinois ranked 15th in quantity and 8th in the value of total clay production. U.S. production of common clay decreased about 5% from 27.2 million in 1991 to 25.9 million in 1992. The total of all clay produced in the United States decreased 15.5%. In 1992, the average value per ton of common clay in Illinois declined from $4.31 to $4.00, making a total value of $2,362,467 for the year. Production of common clay was reported from six companies in four counties. Livingston County was the leading producer of common clay; La Salle County was second; Bond County was a close third; and Kankakee County, fourth. In Pulaski County, only one company (Golden Cat Corporation) reported production of absorbent clay (fuller's earth) at two pits. The combined total of the two pits' production decreased about 20%, whereas their value was about 25% less in 1992.

Uses Common clays and shales mined in Illinois are used to manufacture bricks, drain tiles, dinnerware, and cement. Manufacturing common brick used about 85% of the state's common clay production in 1992; portland cement took 14%; and drain tile required the remaining 1%. Absorbent clay is used in cat litter and oil-sweep compounds, as a filler and pelletizer in animal feeds, and for steel casting.

Fluorspar

Production and shipments One company in southern Illinois was the only producer of fluorspar in the United States. Ozark-Mahoning Company operated three mines the Annabell Lee, Den- ton, and No. 1 mines and a flotation plant near Rosiclare in Hardin County. The company also dried imported fluorspar to supplement production. Production decreased about 5% from 1991 to 1 992. The steady decline can be traced to the decreasing use of chlorofluorocarbons, as a response to concerns about the environment, and to cheaper foreign imports (especially those from China). The United States depends on foreign sources for most of its fluorspar.

Barite, copper, lead, silver, and zinc (sphalerite) concentrates were recovered as coprod- ucts of fluorspar processing in Illinois. In the United States, about 60,000 tons of the byproduct fluosilicic acid (FSA), equivalent to 105,600 tons of 92% fluorspar, was recovered. FSA was used primarily in the aluminum industry for making aluminum fluoride and in water fluoridation, either directly or after processing to sodium silicofluoride.

11

Consumption Reported U.S. consumption of fluorspar (acid spar and metallurgical spar) fell for the fourth year, a drop of about 44% from 651,055 tons in 1988 to 365,000 tons in 1992. More than 65% of the reported production went into hydrofluoric acid, the primary ingredient in most organic and inorganic fluorine-bearing chemicals. Hydrofluoric acid is also used in processing aluminum and uranium. The steel industry took about 15% of the fluorspar produced, using it as a flux and in iron and steel foundries. The remainder was consumed in manufacturing glass, welding-rod coatings, and enamels, and for fluoridating water.

The apparent U.S. consumption (production + imports - exports ± change in stocks) increased 9% from 365,831 tons in 1991 to 399,000 tons in 1992. Apparent consumption has gone down about 45% since 1988. The discrepancy between apparent and reported consump- tion is often large for many minerals, including fluorspar, because users are more numerous than producers or traders, and not all users report consumption to the USBM.

Consumption of metallurgical-grade fluorspar by the steel industry is decreasing drasti- cally, partly because of the drop in steel output, but mainly because of continuing improvements in efficiency and more rigid raw material specifications. These modernizations will probably lower consumption of fluorspar for several years. Further decline in consumption is anticipated as the government restricts use of chlorofluorocarbons in an effort to implement the Montreal Protocol on Substances that Deplete the Ozone Layer.

Sand and Gravel

Since 1981, the USBM has surveyed sand and gravel producers only in even-numbered years. In odd-numbered years, estimates are published. In 1985, the USBM began compiling sand and gravel production by district rather than by county to preserve the confidentiality of the data (fig. 12). Data for individual counties are no longer available.

Production Sand and gravel deposits are widely distributed in Illinois. Glacial deposits, chiefly valley trains and outwash plains, are the primary sources of construction sand and gravel. Environmental restrictions, local zoning regulations, and land development continue to concern the sand and gravel industry. New operations tend to locate away from highly populated areas.

Production in 1992 was 35.7 million tons, about 36% more than the 1991 estimated production. The USBM has not revised their 1991 estimate, which appears to be much too low. The combined value of sand and gravel was $123.7 million (table 19); the average estimated unit value at the pit was $3.47 per ton, about a 1% increase from the 1991 estimate (table 1). Illinois ranked seventh of the 50 states in production of sand and gravel in 1992.

Nine counties (McHenry, Kane, Lake, Du Page, Cook, Tazewell, Grundy, Woodford, and Peoria), each producing more than 1 million tons, accounted for about 70% of the sand and gravel production in Illinois. The concentration of about two-thirds of Illinois' population in Cook and five surrounding metropolitan counties makes a ready market for sand and gravel. District 1 produced 63%; District 2, 11%; District 3, 19%; and District 4, 7%. In 1992, 113 companies operated 149 pits in 54 counties of Illinois (fig. 12). About 38% of the state's production came from operations of 1 million tons per year and more, as compared to 49% in 1990 (table 20). As shown in figure 13, Illinois' sand and gravel production has grown more slowly than its stone production in the past decade, a trend indicating a preference for stone in the construction industry.

Transportation Because of its low unit price, most construction sand and gravel is not shipped farther than 50 miles from the pit, although operations on navigable rivers may ship material much farther by barge. About three-quarters of the material was shipped by truck in 1992; the remainder was shipped by barge or rail, or used at the pit, for example, in asphalt production.

Consumption and uses Production reported is actually material sold or used; stockpiled production is not reported until it is sold or consumed. Illinois sand and gravel is primarily used as various types of construction aggregate for buildings and road construction.

Industrial Sand

Production The area best known for production of industrial (silica) sand from the St. Peter Sandstone of Middle Ordovician age is the Ottawa district of La Salle County. Within the district, the St. Peter is called the Ottawa Sand. Illinois again ranked first of 37 states in industrial sand

production. The 4.4 million tons (17% of the U.S. total) produced in 1992 was a 6.4% increase over the estimated tonnage for 1991. The total value decreased about 1% to $56.7 million. The average unit value was estimated at $12.87 per ton, a decrease from the estimated $13.80 for 1991. Five companies operated six pits in La Salle, Mason, and Ogle Counties.

Transportation Industrial sand was shipped mainly by rail in 1992; however, a significant amount is still shipped by truck and a small amount by barge.

Consumption and uses Industrial silica sand was produced in both ground and unground forms. Unground sand is used primarily in glass manufacturing. Other uses include sand for molding, blasting, grinding and polishing, railroad traction, filtration, and propping (frac sand) for hydrofracturing reservoir rock in oil wells. Ground sand is used in chemicals, abrasives, enam- els, pottery, porcelain, tile, and various fillers.

Unimin Corporation, U.S. Silica Company, Manley Brothers, and Fairmont Minerals Ltd. mined silica sand in the Ottawa district of La Salle County, and Unimin's operation in Ogle County mined sand for glass, blasting, foundry, and frac sand markets. Manito Investment

Stone

Since 1981, the USBM has surveyed stone production only in odd-numbered years. Estimated data are given for 1992 and actual data for 1991. In 1985, the USBM began compiling stone production in Illinois by district (fig. 14). Data for individual counties are no longer available.

Production Limestone and dolomite quarries are located where thick stone deposits occur near the surface because of upwarping of bedrock and erosion of overlying materials.

Crushed stone is the state's most important rock product. In 1992, Illinois continued to rank second in production of crushed stone among 49 producing states. An estimated 72.7 million tons of stone was produced Illinois in 1992, a 6% increase from 68.6 million tons produced in 1991. Total value was estimated at $322.8 million, a 9.3% gain. In 1991, the last year for which actual figures are available, 53 of the state's 102 counties reported production (fig. 14). A small amount of dimension stone was produced by one producer in Kane County.

Shipments Stone, a bulk commodity, is used primarily near the quarry, so more than one-half of the stone produced was transported by truck. A small percentage was used at the site and the remainder went by rail or barge. Waterways were put to use by some producers along the Illinois, Ohio, and Mississippi Rivers. Crushed stone was barged to in-state destinations as well as to Pennsylvania and Gulf Coast markets in Alabama, Texas, and Louisiana. The Illinois Central Railroad uses stone produced in Illinois for ballast throughout its entire system.

Consumption and uses Stone is used primarily as construction aggregate in portland cement, in bituminous highway construction as road-base stone, and in manufacturing portland cement. It also has chemical, agricultural, and environmental uses. The small amount of dimension stone mined in Illinois is used as veneer for houses, small retaining walls, rubble, and flagging.

Tripoli

Production The term tripoli refers to microcrystalline silica. Unimin Specialty Minerals Inc., a division of Unimin Corporation, is the nation's leading producer of tripoli. Located in Alexander County in southern Illinois, Unimin is the only producer of high-grade tripoli in Illinois.

14

Figure 14 Districts and counties producing stone in 1991.

Tripoli is mined in only four states. Illinois has remained the nation's largest producer of tripoli and accounts for more than 70% of the total U.S. production in 1992. Tripoli production figures are confidential.

Consumption and uses Tripoli processed in Illinois is used as filler in paints, plastics, and rubber products, and as an abrasive in buffing and polishing compounds, soap, and toothpaste. Some iron-stained tripoli is now being used in the manufacture of portland cement.

Metals

Zinc, Lead, Silver, and Copper

Production Minerals bearing zinc, lead, silver, and copper are recovered from fluorspar ore mined in Hardin County by Ozark-Mahoning Company. In 1992, zinc (sphalerite concentrate) production increased about 9% and value jumped 20%. Small amounts of lead, copper, and silver were reported for 1992. These metals, byproducts of the fluorspar industry, have been produced in relatively small quantities and only add a small amount to the total value of miner- als produced in the state.

15

Other Minerals

Peat

All commercial sales of peat in the United States (excluding imports) are for agriculture and horticulture. Three types of peat reed sedge, moss, and peat humus were produced in Illi- nois by four companies: Dahl Enterprises and Roots Peat Farm in Lake County, and Hyponex Corporation and Markman Peat Company in Whiteside County. Illinois ranked fifth of 20 states in production of peat. In 1992, peat production and value jumped 41% and 34%, respectively. More than 96% of the state's peat was sold in package form for general soil improvement. Small amounts were sold in bulk form for nurseries and earthworm cultivation.

Gemstones

Production of fluorite and accessory minerals is limited to mineral-specimen grade in Illinois. As a result, gemstones contributed little to the total value of mineral production. The estimated value of gemstones must be withheld in Illinois; however, it increased about 31% in 1992. Illi- nois ranked 15th of 50 states producing gemstones.

MINERALS PROCESSED

Minerals extracted mainly in other states or foreign countries but processed in Illinois include ground barite, calcined gypsum, crude iodine, iron-oxide pigments, natural gas liquids, expand- ed perlite, pig iron, sulfur, exfoliated vermiculite, primary slab zinc, and secondary slab zinc. The total value of processed minerals is incomplete because the two largest producers of pig iron did not respond to the USBM annual survey and, therefore, no figures are available for pig- iron production in the state.

Ground Barite

J. M. Huber Corporation in Quincy, Adams County; American Minerals in Rosiclare, Hardin County; and Harcros Pigments in East St. Louis, St. Clair County, continued to process ground barite. The ground barite processed in Illinois is used almost exclusively as a filler or extender in paints.

Columbium and Tantalum

Fansteel in Cook County is no longer processing columbium-tantalum concentrate imported from foreign countries, but the firm retains a corporate office in North Chicago. Columbium and tantalum are used primarily to produce various steel alloys.

Calcined Gypsum

The National Gypsum Company in Lake County processed calcined gypsum from gypsum mined in Michigan. The product is used primarily for prefabricated housing materials such as wallboard, which is increasingly in demand. It is used in manufactured (mobile) homes and in the building and remodeling of homes and offices. Repair and remodeling remained a strong market for the gypsum industry.

Production and value of calcined gypsum increased about 10% in 1992 as the economy began to gain slowly. Although gypsum wallboard prices hit a 14-year low early in 1992, they rebounded by the end of the year and were expected to continue rising during 1993 as the con- struction industry continued to recover.

Crude Iodine

Crude iodine was processed into inorganic compounds for commercial use at three Illinois plants: Allied Signal Company in Metropolis, Massac County; West Agro in Des Plaines, Cook County; and ECHOLAB in Joliet, Will County. Although crude iodine is used primarily as a catalyst or stabilizer, it also is added to animal feed, salt, inks, colorants, pharmaceuticals, sani- tary products and industrial disinfectants. Consumption in Illinois increased about 32% in 1992.

Iron-Oxide Pigments

Finished pigments were produced from iron ore imported from other states by five companies: the Prince Manufacturing Company in Adams County, George B. Smith Color Company in Kane County, AST Company in Madison County, Harcros Pigments in St. Clair County, and Solomon

16

Grinding Service in Sangamon County. The types of natural iron-oxide pigments produced included black (magnetite), brown iron oxide, red iron oxide (including pyrite and cinder), and yellow iron oxide. Synthetic black, brown, red, and yellow iron oxides were also produced. Illi- nois continued to rank second nationally in value of finished iron-oxide pigments.

Natural Gas Liquids

Natural gas liquids include ethane, propane, isobutane, unsplit butane, and a combination of gasoline and liquefied petroleum gas. Natural gas liquids were processed in Douglas County by the U.S. Industrial Chemical Company, a division of Quantum Chemical Corporation. The U.S. Department of Energy reports that the 942 million cubic feet of gas processed in Illinois in 1992 was all produced in Illinois. The total liquids extracted from gas in Illinois amounted to 88,000 barrels.

Expanded Perlite

Crude perlite mined outside the state was processed to expanded perlite by three companies: Silbrico Corporation in Cook County, Illinois Strong-Lite Products Corporation in La Salle County, and Manville Products Corporation in Will County. (Scheller International Corporation acquired Manville Products in 1992.) Production and value of expanded perlite decreased 6.2% and 15.1%, respectively, but the average price per ton increased 8.4% in 1992. Illinois ranked fifth of 33 states in quantity of expanded perlite sold and used.

Expanded perlite is used primarily in roof insulation board and for horticultural purposes. Other uses include lightweight aggregate for concrete and plaster, insulation, and filters.

Pig Iron and Raw Steel

The American Iron and Steel Institute in Washington, D.C., ranked Illinois fifth in raw steel production. The state produced 7.24 million tons or 8.6% of the U.S. output in 1992. Although there was a slight gain in raw steel production less than 1% in 1992 major changes seem to indicate problems.

Acme Steel Company changed its name to Acme Metals Inc. to reflect corporate restruc- turing— not the company's basic strategy of making steel for niche customers. Acme produces steel, steel strapping and strapping tools, welded steel, pipes and tubes, and automotive jacks. Acme is studying the feasibility of installing a thin slab caster/hot strip mill at its Riverdale facil- ity to replace the present ingot pouring and rolling and narrow hot strip mill facilities. It would use steel produced in Acme's basic oxygen furnace, also at Riverdale in Cook County.

Inland Steel Company has been restructuring to reduce losses and staff. They hope to cut staff by 3,600 to 4,000 workers. Laclede Steel Company is also restructuring. They will close their wire mill in Alton, Illinois, and expand their wire-making facility as well as construct a recovery plant to process hazardous dust in Hammond, Indiana. The Hammond operation is closer to the company's major market. Laclede's mini-mill at Alton will not be affected by the closing. National Steel Corporation will shut down its cold-roll finishing units at their Granite City steel plant. Some employees will be transferred to the Mishawaka plant in Indiana where they are moving their headquarters from Pittsburg, Pennsylvania.

The St. Anne Foundry plant at Kankakee in Kankakee County was destroyed by fire, but the company has indicated that it will rebuild. USX Corporation closed its southeast Chicago South Works steel mill. They are negotiating with a mini-mill operator, which plans to purchase the plant for manufacture of stainless steel. Civic leaders are also evaluating the site for a housing project to relocate people, if a new airport is located at Lake Calumet.

Several companies have announced new plants or facility upgrades. Amsted Industries of Chicago plans to reopen Am Steel Foundries in Granite City. Birmingham Steel Corporation's Illinois Steel Division at Kankakee has been completely upgraded. Laclede Steel has improved its pipe finishing and shipping facility in Vandalia, Fayette County, and its caster mold and electric arc furnace in Alton, Madison County. National Steel, the nation's fourth largest steelmaker, brought its new slab caster online at its Granite City steel plant.

In the United States, pig iron was produced by 15 companies in approximately 60 blast furnaces, of which 42 to 44 were in continuous operation. Five blast furnaces are in Illinois. At the same site, steel-making furnaces used most of the pig iron in liquid form for refining raw steel.

17

Slag (Iron and Steel)

In 1992, Illinois ranked fifth of 28 states in the quantity of iron and steel slag sold or used. Four companies operating eight plants in Clay, Cook, Madison, and Whiteside Counties processed slag from iron and steel furnaces. The slag was used mostly for construction aggregate road- base material, asphaltic concrete, railroad ballast, and fill and also for the manufacture of mineral wool.

Recovered Elemental Sulfur

Illinois ranked seventh nationally of 28 states in quantity and value of recovered elemental sul- fur. Four companies in three counties, Crawford, Madison, and Will, recovered elemental sulfur as a byproduct of their oil refinery operations. Although sales of sulfur increased 12.2% from 239,736 tons in 1991 to 269,062 tons in 1992, its total value decreased 29.7% from $17.5 million in 1991 to $12.3 million in 1992, indicating a precipitous drop in sulfur prices. Sulfur differs from most other major mineral commodities in its primary use as a chemical reagent rather than as a component of a finished product. The largest use is for agriculture, as a component of phosphatic fertilizers.

Exfoliated Vermiculite

Illinois ranked third nationally of 20 states in quantity of exfoliated vermiculite sold in 1992. Exfoliated vermiculite processed from crude vermiculite mined outside the state was produced by three companies in Du Page, La Salle, and Macoupin Counties. Sales increased 17.8% and value, 17.4%, in 1992. The average value per ton decreased slightly (0.4%). In Illinois, exfoli- ated vermiculite has the following uses:

Primary and Secondary Slab Zinc

U.S. refined metal production was up slightly from 1991 and the highest since 1981. Only three companies in the United States operated four primary zinc refineries, including one in Illinois: the Big River Zinc Company at Sauget.

U.S. smelter production was near capacity and the highest since 1981. There were ten secondary smelters processing secondary slab zinc in the United States, including one in Illinois: the Illinois Smelting Company in Cook County.

Although production data for individual states are not available, consumption data indicate that Illinois was the top consumer of slab zinc and accounted for more than 15% of the reported U.S. consumption.

Most of the secondary feed was crude zinc calcine recovered from dust generated by steel- making using electric arc furnaces (EAF). The dust was processed at the Horsehead Resource Development Company (HRD) plants in Illinois, Pennsylvania, and Tennessee. At Alton, Illinois, Laclede Steel Company was constructing a facility that could process 36,000 tons of EAF- generated dust per year. Production was scheduled for early 1992.

Eagle Zinc Company at Hillsboro, Illinois is the only domestic producer of zinc oxide by the American process. This is sold directly for use in animal feed and other agricultural purposes.

PRODUCTS MANUFACTURED FROM MINERALS

MINED IN AND OUT OF STATE

Cement

Production In 1992, portland cement manufacturing in Illinois consumed an estimated 4.0 million tons of raw materials. Raw materials may include cement rock (an argillaceous lime- stone containing calcium, silica, alumina, and magnesia), limestone, clay, shale, sand, fly ash, slag, gypsum, and tripoli. Illinois ranked eighth of 39 states in quantity of portland cement pro- duced. Masonry cement contributed little to the total value of products manufactured, and Illi- nois ranked last of 36 states producing masonry cement. Cement was produced by the Illinois

Cement Company, a subsidiary of Centex Corporation, and Lone Star Industries, both in La Salle County; Dixon-Marquette Cement, a subsidiary of Prairie Materials Sales in Lee County; and Missouri Portland Cement Company, a division of Cementia Oldings AG in Massac County. All four companies produced portland cement, and all except Illinois Cement Company pro- duced masonry cement, although in very small quantities.

Sales of portland cement increased 1.3% in 1992, with the value per ton increasing about 1% from $41.21 in 1991 to $41.61 in 1992 (table 22). Nearly all the cement was delivered by truck in bulk form, although small amounts were shipped by rail and barge.

Consumption Illinois ranked fourth behind California, Texas, and Florida in consumption of cement products in 1992. About 3.3 million tons of portland cement (fig. 15) and 73,452 tons of masonry cement were consumed in Illinois. According to these figures, the use of portland cement decreased by 10.8%, and masonry cement, by 9.8%. Beginning in the late 1970s and 1980s, an increasing portion of the cement consumed in the state was also was being manu- factured in the state.

Clay Products

For up-to-date information about the amount and value of clay products manufactured in Illinois, the Illinois State Geological Survey sends questionnaires every year to all in-state producers.

In 1992, clay products were valued at $54.1 million, 13.6% lower than in 1991. Whiteware and pottery decreased from $36.1 million in 1991 to $34.7 million in 1992. All other clay prod- ucts decreased from $26.5 million in 1991 to $19.4 million in 1992. The Regal China Company at Antioch in Lake County closed on June 30, 1992, after showing no production for the year.

Coke

Production All data on coke production in Illinois have been withheld. U.S. production decreased about 2.6% from 24.0 million tons in 1991 to 23.4 million tons in 1992. U.S. coke breeze production decreased less than 1%.

Consumption and uses Coke is used for pig-iron production, foundry and other industrial purposes, and residential heating. U.S. coke consumption increased 8.9% from 27.5 million tons in 1991 to 30.0 million tons in 1992. The United States imports coke from Japan and smaller amounts from Australia, Canada, and United Kingdom. Coke breeze was used as fuel in steam and agglomerating plants. State-by-state data on coke breeze are no longer available. U.S. breeze distribution increased 9.6% from 2.1 million tons in 1991 to 2.3 million tons in 1992.

Glass

Glass and/or fiberglass is manufactured in Du Page, Lake, La Salle, Logan, McLean, Macon, Madison, Marion, Montgomery, St. Clair, and Will Counties. Production data are not available. Ball Corporation purchased the assets of Kerr Glass Manufacturing Corporaton, which manufac- tures glass containers mainly for the food processing industry. The Kerr manufacturing facility in Plainfield, Will County, was included in the purchase.

Lime

Production Illinois ranked seventh of 33 states in production of lime. The top seven states Missouri, Ohio, Pennsylvania, Alabama, Kentucky, Texas and Illinois accounted for 63% (11.3 million tons) of the total U.S. output. Although Illinois lime data cannot be disclosed, both production and value increased about 1% after decreasing about 10% in 1991. Three plants in Cook County supplied the state's entire output. Two plants owned by Marblehead Lime Com- pany, a division of General Dynamics, produced quicklime and hydrated lime; the Vulcan Materials Company plant produced quicklime. Marblehead Lime Company, with two plants in Illinois and one each in Indiana and Michigan, was the third largest company producing lime in the United States in 1992.

Consumption and uses In 1992, Illinois consumed 546,000 tons of quicklime, 9.5% less than in 1991, and 182,000 tons of hydrated lime, 3.4% more than in the previous year (fig. 16). The steel industry remains the main consumer of lime, which is used as a flux in steel refining to remove impurities. In recent years, since the steel industry has been in a depressed state, con- sumption has been relatively low. Steel output is expected to increase modestly, however, as power plants, municipal water plants, and chemical firms showed an increased use of lime. Lime consumption for flue gas desulfurization is expected to show some growth as a result of the passage of the Clean Air Act Amendments (CAAA) of 1990. The phase I compliance dead- line is January 1, 1995, which means that utility companies have decided on their compliance strategies by this reporting in mid-1994. If the use of lime is a tactic in the compliance strate- gies, the consumption data for 1993 and 1994 should show an increase.

PREUMINARY PRODUCTION DATA: 1993

Minerals Extracted

The total value of minerals mined in 1993 was an estimated $2.1 billion, a decrease of 20.6% from 1992, according to preliminary data (table 23). This decrease reflects the 30% drop in coal production, mainly due to a strike by the United Mine Workers of America (UMWA). Even then, coal continued to be the leading mineral commodity in Illinois and contributed about 56.4% of the total value. The construction aggregates stone, sand and gravel ranked second with 25.4% of the total value, and crude oil came in third with 16.1%.

Fuels

Fossil fuel production was valued at about $1.5 billion in 1993, 26.4% less than in 1992.

Coal The estimated per ton value of coal in 1993 was $27.66, the same as in 1992. Coal production decreased an estimated 30% to 42.2 million tons in 1993 because of the UMWA strike. This drop will put Illinois in sixth place nationally behind Wyoming, Kentucky, West Virginia, Pennsylvania, and Texas.

Consumption of Illinois coal in the United States during the first 9 months of 1993 dropped 26.6% (table 24). Total coal consumed in Illinois in the first 9 months was up slightly (1.1%) after decreasing about 6% in 1992 (table 25). Some electric utility companies turned to stock- piles to make up for deliveries disrupted by the strike and the severe flooding that closed the Mississippi River to barge traffic for about 6 weeks.

The Illinois Coal Development Board (ICDB) broke ground for a coal gasification plant at the Illinois Coal Development Park in Carterville. The plant will test a process to convert Illinois high-sulfur coal into environmentally safe and economically efficient products. The process will also generate liquid byproducts for use in making plastics and gasoline, and another byproduct that will be used to help operate other commercial mild-gas plants.

Crude oil and natural gas Crude oil production in 1993 is estimated to be 19.1 million barrels, a 1.7% decrease from production in 1992 (table 23). Production is estimated to have a value of $17.50 per barrel, making the total worth $334.1 million. Oil price per barrel is estimated to have decreased about 9% from 1 992.

Natural gas production and value are estimated to have decreased more than 22%. The estimated unit value is $2.30 per Mcf in 1993.

Industrial and Construction Materials

The major flooding that occurred in the Mississippi and Illinois River valleys during the summer of 1993 had little impact on Illinois mineral producers. Only a few had to shut down. Those affected most were dependent on barges for transportation.

Illinois continued to rank 16th nationally in the value of nonfuel minerals produced in 1993 and accounted for 2.32% of the nation's total. Preliminary data for 1993 show Illinois still leading the nation in production of fluorspar, industrial sand, and tripoli and ranking second in production of crushed stone. Stone and sand and gravel increased slightly, both in production and value; whereas clays dropped significantly in 1993. The industrial minerals sector is expected to rebound slowly, given relatively low interest rates for housing starts and also the support of the Federal highway construction program.

Metals and Other Minerals

Zinc (sphalerite concentrate) and barite were the only byproducts for which production esti- mates were reported from the Illinois fluorspar mines in 1993. Zinc production was estimated to have decreased 2%, whereas barite was expected to have decreased 75%. Copper and lead were also mined in 1993, but estimates of their production were not available. Production of these metals, byproducts of the fluorspar industry, remained relatively small, adding less than 2% to the state's nonfuel mineral production.

Minerals Processed

Preliminary data for 1993 are not yet available for most of the minerals processed in Illinois. The American Iron and Steel Institute reported that Illinois raw steel production increased to

21

7,948,655 net tons, up 9.7% from 1992. The steel plants are continuing to restructure and upgrade to be more efficient and economical but less expensive to operate as they try to keep pace with foreign competition.

Gains made by the gypsum industry are expected to continue in 1993 as residential con- struction, primarily of single family housing, continues to grow. Industry reports indicate that home repairs and remodeling, including "do-it-yourself" projects, constitute the growth sectors.

Products Manufactured from Minerals

Preliminary figures for 1993 show that production and value of portland cement were approxi- mately the same as they were in 1992. Illinois remains a top consumer of portland cement. Masonry cement production stayed about the same as in 1992; however, its value is expected to decrease. It is expected that lime production and value will increase slightly (less than 1%). As more clay-product plants go out of business, clay production will probably drop.
