THE MINERAL INDUSTRY OF UTAH

mine of United States Steel Corp. (USS), and the Iron Springs and McCahillThompson
Alluvial: mines of Utah Construction & Mining Co. The Desert Mound mine
led in production. No production was reported from the Duncan mine by CF&I.

 A multimillion dollar addition was begun at the Geneva works of USS to produce
wire-flange beams. Geneva will be the only plant west of Denver producing
this item.

 Lead.—Lead production from 11 mines in seven counties decreased 16
percent. The five largest producing mines in order of rank were the U.S.
and Lark mine of USSR&M Co.; the Burgin mine, Tintic Division, Kennecott
Copper Corp.; the Mayflower mine, Hecla Mining Co.; the United Park City
mines, United Park City Mines Co.; and the Ophir mine, USSR&M Co.; (McFarland
& Hullinger, lessees). An increase in production was reported only from
the Ophir mine. 
 The daily ore production at the Burgin mine exceeded the design rate of
500 tons per day for the first part of the year; caving ground conditions,
however, limited production, and thus the yearly average was 466 tons per
operating day. Plans were announced to increase the daily mining rate to
800 tons in early 1969 and to complete a 500-ton-per-day concentrator in
1968 near the Burgin mine. 
 
 Molybdenum.—Molybdenum sulfide was recovered from the copper ore processed
by Utah Copper and a large portion converted to molybdic oxide in a recently
completed plant. Because of the strike, production was 36 percent below the
1966 level. 
 
 Rhenium.—Production of rhenium was down because of the reduction in
copper mining. Utah Copper was the only producer of rhenium. 
 Selenium.—Selenium, recovered as a byproduct of the electrolytic refining
of copper, was shipped from the Garfield plant of Kennecott Copper; shipments
increased 22 percent. 
 
 Silver.—Mostly because of the strike, production decreased 37 percent.
In order of rank, the four leading companies in silver production were Kennecott
Copper Corp., USSR&M Co., Hecla Mining Co., and United Park City Mines
Co. Total silver production came from 20 mines in 10 counties. In the United
States, only Idaho produced more silver than Utah. 
 
 Uranium.—Although the number of uranium operations decreased from
208 to 117, uranium production increased 5 percent. Emery, Garfield, and
Grand Counties reported decreases; Piute and San Juan Counties reported increases.
The average ore grade remained at 0.26 percent (5.3 pounds per ton). 
 Prospecting for uranium almost reached a record high. Several mining companies
established exploration offices in Monticello; in San Juan County, a total
of 2,070 mining claims was filed during the first 11 days of October. Grand
County also reported increased uranium activity. 
 
 Vanadium. — Vanadium output, recovered from Utah uranium ores at four
locations, increased 33 percent over the 1966 figure. The mill at Grand Junction,
Cob., had a substantial increase in vanadium output from Utah ores. A new
vanadium oxide recovery circuit at the Moab uranium processing mill went
into operation March 7 and contributed to the increased production.
