 THE MINERAL INDUSTRY OF UTAH 7~5 
 
 Pyrites.—Pyrite production (from two operations) more than doubled
the previous years output. The pyrite, shipped to The Anaconda Company, Yerington,
Nev., was used for manufacturing sulfuric acid. 
 
 Salt.—Since no shipments were reported for manufacturing chlorine,
production of salt decreased 6 percent (24,000 tons). Evaporated salt was
produced by five companies—Hardy Salt Co. in Tooele County, Lake Crystal
Salt Co. in Box Elder County, Morton Salt Co. in Salt Lake County, Solar
Salt Co. in Tooele County, and Utah Salt Co. in Tooele County. Rock salt
was produced by two companies—Albert Poulson Salt Co. in Sanpete County
and Redmond Clay & Salt Co. in both Sanpete and Sevier Counties. Only
30 percent of the salt was used in Utah. The output of both evaporated and
rock salt decreased. 
 
 Sand and Gravel.—With the lowest annual production since 1960, sand
and gravel decreased 3 million tons (24 percent) from that of 1966.. The
use of sand and gravel for road construction decreased 2.6 million tons (30
percent) and for building, 900,000 tons (28 percent). Production was from
166 operations in 28 counties. More than half of the commercial production
came from 13 pits, each with more than 100,000 tons annual production; only
7 percent of the commercial production came from 35 pits each with less than
25,000 tons annual production. 
 
 Stone.—The output of stone decreased 18 percent in quantity but only
4 percent in value. Production of crushed mis- 
cellaneous stone and crushed sandstone both decreased substantially. 
 Crushed limestone (97 percent of the total stone production) was used as
a fertilizer filler, flux, mineral food, poultry grit, railroad ballast,
raw material in making cement and lime, and stone sand; in cast stone panels,
refractories, and road construction; and for controlling coal dust in coal
mines, landscaping, and roofing gravel.
