794 MINERALS YEARBOOK, 1967 
 
(11.4 million barrels) and Texas (2.1 million barrels). At yearend, Caribou
Four Corners Oil Co. was completing an expansion to its Woods Cross refinery;
crudeoil capacity was increased to 12,000 barrels per day; a 1,500-barrel-per-day
vacuum unit and a 2,000-barrel-per-day Unicracker-JHC were added. 
 
NONMETALS 
 
 Earite.—No production of barite was reported in Utah during 1967.
Crude barite prepared for use in well drilling by Yuba Minerals & Milling
Co., Salt Lake City, came from four operations in Nevada. 
 
 Cement.—The output of portland cement decreased 13 percent. Ideal
Cement Co. at Devil's Slide in Morgan County was the main producer of cement.
A $3 million modernization program for handling materials throughout its
operation was completed by Portland Cement Company of Utah near Salt Lake
City. 
 On December 31, Potash Company of America and Ideal Cement Co. merged to
form Ideal Basic Industries, Inc. Each company will continue to operate its
own business as a division of Ideal Basic Industries, Inc. 
 
 Clays.—The output of clay increased 6 percent in quantity and decreased
11 percent in value. Production of fire clay and halloysite declined; however,
output of bentonite, fuller's earth, and miscelleneous clays increased. Although
clays were used by many industries, 90 percent of the total output was used
in manufacturing building brick, as a catalyst in oil refining, and as a
raw material for lightweight aggregate. Clays were produced at 19 operations
in nine counties. 
 
 Fluorspar.—Shipments of fluorspar, used entirely at steel mills, increased
42 percent. A new mine was opened in Millard County but the major production
cams from a mine near Spor Mountain in Juab County. 
 
 Gypsum.—The output of gypsum from two operations near Sigurd increased
8 percent. A metallurgical process to remove sulfur from gypsum had been
developed by the Bureau of Mines Metallurgical Research Center in Salt Lake
City which permits recovery of 1 ton of sulfur from 
7 tons of gypsum. Companies with large reserves of low-cost gypsum in Utah
were considering the use of the process to produce sulfur. 
 
 Lime.—Lime production decreased 16 percent (31,000 tons) because less
lime was used in the construction trade, in agriculture, in the refractory
industry, and in the chemical industry. A slight increase in the use of lime
was reported at beet sugar plants. Companies producing lime were The Amalgamated
Sugar Co.; U.S. Lime Division, The Flintkote Co.; Utah Copper Division, Kennecott
Copper Corp.; Lakeside Lime, Inc.; Utah Marblehead Lime Co.; and Utah-Idaho
Sugar Co. Three of these companies produced lime only for use in their own
operations. 
 
 Magnesium Chloride.—A substantial increase in the production of magnesium
chloride from Great Salt Lake, the only production reported in Utah, was
at the Bonneville, Ltd., plant of Kaiser Aluminum & Chemical Corp. 
 
 Perlite.—Production of crude perlite was greatly reduced at the North
Pearl Queen mine of Henry~Schoo Co., the only source of crude perlite in
the State. 
 
 Phosphate Rock.—San Francisco Chemical Co., with mines in Rich and
Uintah Counties, was the only producer of phosphate rock. Output decreased
13 percent, partly because sulfuric acid used to process the ore at the Garfield
plant of Stauffer Chemical Co., Fertilizer Division was no longer available
from Kennecott Copper Corp. 
 
 Potash.—The output of potassium salts increased 27 percent. Production
gains were reported by Texas Gulf Sulphur Co. and'Kaiser Aluminum & Chemical
Corp. 
 A second shaft was sunk at the Cane Creek potash min~ of Texas Gulf Sulphur
Co. The concrete-lined shaft had a cased inside diameter of 4 feet and a
depth of 2,710 feet; the first 300 feet was 8 feet in diameter. A 450-ton-per-day
crystallizer, under construction to recover previously lost fine materials,
was scheduled for completion early in 1968. 
 
 Pumice.—Production of pumice decreased 83 percent. All of the product
from the three producing mines was used as an aggregate in concrete.
