 THE MINERAL INDUSTRY OF INDIANA 195 W Withheld to avoid disclosing company
proprietary data.' Data may not add to totals shown because of independent
rounding. 
 Perlite.—Imported perlite mined in New Mexico was expanded by
five
companies operating six plants. United States Gypsum Co. operated plants
in Lake and Martin Counties; National Gypsum Co., in Martin County; Grefco,
Inc., in Montgomery County, Chemrock Corp., in Tippecanoe County; and Johns-Manville
Corp., in Madison County. Production during 1978-79 totaled almost 50,000
short tons valued at $5.9 million. Principal uses were for filter aids, fillers,
plaster aggregates, cavity fill, and roof insulation board. 
 Sand and GraveL—Indiana's sand and gravel industry remained stable
in 1978-79. During the biennium, little change occurred in tonnage or in
the number of mining operations, processing plants, and companies. Construction
sand and gravel accounted for most of the production; it was used mainly
for concrete aggregate, roadbase, fill, and asphaltic concrete. 
 Indiana produced a small quantity of 
industrial sand in La Porte, Warren, and Porter Counties. Major uses were
for refractories, silicon carbide manufacture, and foundry molding and core.
Most of Indiana's glassmaking companies imported sand from out of State.
Rail deliveries averaged about 3,000 short tons per day to eight glass manufacturers
in the west-central 5part of the State. 
 Slag.—Indiana ranked third nationally in the production of blast
furnace
slag during 1978-79. Once a major waste problem for the iron and steel industry,
slag currently has a myriad of applications in many phases of construction.
Slag was used as all-purpose construction aggregate, road base material,
bituminous aggregate, railroad ballast, filter media, and for septic tank
absorption beds. 
 Stone.—During both 1978 and 1979, Indiana ranked 15th nationally
in
total stone production, and first in dimension stone output. Of all stone
mined in 1979, lime-
