Illinois ranked fourth in production among the nine States that produced fuller's earth in 1979. The material absorbs more water than common clay and was used in oil refining for decolorizing and purifying purposes. Fluorspar.—Although Illinois continued to be the Nation's leading producer, shipments in 1978 and 1979 were the lowest of the decade, except for those of 1975. The decline was attributed to market conditions and foreign imports. Fluorspar was mined in Hardin County by the Hastie Mining Co., Ozark-Mahoning Co., and Allied Chemical Corp. At yearend 1979, Allied ceased operations pending sale of the company's fluorspar holdings. During the 1978-79 period, OzarkMahoning operated the Barnett, Oxford No. 7, Knight, and H. M. mines. The company began sinking the Henson shaft, developed a new vein through a crosscut from the Barnett mine, and completed the Denton shaft. Fluorspar was used by the chemical, glass, ceramic, and steel industries. Gem Stones.—Small quantities of mineral specimens were collected in the southern Illinois fluorspar district by hobbyists and members of lapidary clubs. Gypsum.—National Gypsum Co. imported crude gypsum from Michigan and Canada in 1978 and 1979. The material was calcined at the company's Waukegan plant in Lake County for use in wallboard. Lime.—Both quicklime and hydrated lime were produced by Marblehead Lime Co. at two plants in Cook County. In 1979, Marblehead began construction of a 1,450short-ton-per-day kiln at its South Chicago plant. Vulcan Materials Co., also in Cook County, produced quicklime. Major uses of lime were in. steelmaking, refractories, water purification, and sewage treatment. Peat.—Illinois ranked third in the United States in peat production, contributing about 10% of the national total in 1978 and 1979. After processing by drying, shredding, and screening, the peat was used almost exclusively in agricultural and horticultural applications. Transportation (by truck) added significantly to the cost of peat because of its bulk. Perlite.—Illinois led the Nation in the quantity of expanded perlite produced in 1979. Crude perlite mined outside the State was processed by five companies in Cook, De Kalb, Lake, and Will Counties. Uses were for insulation, horticultural purposes, as construction aggregate, and as a filter aid. Sand and Gravel.—Nationally the State ranked sixth in output in 1978 and again in 1979. In terms of value, sand and gravel continued to be the second leading nonfuel commodity mined in Illinois. In 1979, production was from 62 of the State's 102 counties at over 200 locations. Most of the construction sand and gravel that was mined was used for aggregate, roadbase, and fill. Industrial-quality sand was used mainly for glass manufacturing and for foundry molding and core.
