THE MINERAL INDUSTRY OF MISSOURI 309 in both years was achieved by three firms: Dundee Cement Co., Harbison-Walker Refractories, division of Dresser Industries, Inc., and Kaiser Aluminum & Chemical Corp. Clay was mined in 22 counties, most ~f which are in east-central Missouri. In addition, mining occurred in one county in the north-central part of the State, two counties adjacent to Kansas City, and two counties in the southeast adjacent to the Mississippi River. The leading counties, in order of decreasing output, were Pike (common clay), Gasconade (kaolin and fire clay), Montgomery (fire ciny), and Audrain (fire clay). Their combined output in 1979 exceeded 55% of the State's total clay production. Common clay and shale were also produced in Boone, Butler, Cape Girardeau, Crawford, Jackson, Jefferson, Livingston, Platte, Ralls, and St. Louis Counties. Fire clay was also mined in Callaway, Franklin, Manes, Monroe, Montgomery, Osage, St. Charles, and Warren Counties. Fuller's earth was mined in Scott County in 1978. About 63% of all the clay mined was common clay and shale, 34% was fire clay and kaolin, and fuller's earth made up the remainder. Fire clay provided approximately 73% of the value of the clay produced in Missouri, followed by 22% from common clay and shale; the remainder came from kaolin and fuller's earth. Fire clay had an average unit value of about $19 per ton in 1979. The unit values of kaolin and common clay and shale were about $17.83 and $2.91 per ton, respectively. Fuller's earth produced in 1978 had a unit value of about $45 per ton. About 75% of the fire clay was used in the manufacture of fire brick, blocks, and shapes. High-aluminum refractories; refractory grogs; refractory mortar and cement; and medical, pharmaceutical, and cosmetic items were other manufactures from fire clay. Aluminum sulfate (alum) was manufactured from kaolin. Face brick and common brick, portland cement, lightweight aggregate for concrete block, and flower pots were manufactured from common clay and shale. Fuller's earth was used in the preparation of oil and grease absorbents and in pesticide carriers and related products. The manufacture of portland cement utilized about 74% of common clay and shale.

Lime.—Led by output from the Ste. Genevieve plant of Mississippi Lime Co., the Nation's most productive such plant in 1979, Missouri's lime production ranked third in the Nation. Output of lime had increased annually from 1975 through 1978, but declined slightly in 1979 to a level about 11.5% greater than in 1975. Annual increases of value in 4 successive years brought the value of produced lime in 1979 to about 73% above the 1975 value. Annual average unit value of lime also increased from about $23.30 per short ton in 1975 to $39.21 per short ton in 1979. About 79% of the product and 73% of the product value was quicklime; the remainder was hydrated lime. Valley Mineral Products Corp. at Bonne Terre produced dolomitic quicklime and refractory dolomite; Ash Grove Cement Co. at Springfield and Mississippi Lime Co. at Ste. Genevieve prepared high-calcium lime. Total shipments of lime from all sources to consumers in Missouri were 229,000 tons in 1978 and 223,000 tons in 1979. The principal uses of lime were in steel manufacturing, in water treatment, and for manufacture of chemicals. Perlite.—J. J. Brouk & Co. in St. Louis and Georgia Pacific Corp. in Cuba expanded perlite in 1979. Production remained essentially unchanged during the 2 years, but the value of the perlite increased as a result of a rise of almost 15% in unit value. The expanded perlite was used in the preparation of plaster and concrete, for low-temperature insulation and cavity fill, as a
