536 MINERALS YEARBOOK, 1972' Mine stocks as of Dec. 31. 
and provided 53% of total U.S. shipments for the year. The lead and zinc
byproducts of the Illinois fluorspar mines were also important to the operations.
Other producing States were Colorado, Montana, Nevada, Texas, Utah, Arizona,
New Mexico, and Kentucky where byproducts were not significant. By producing
at about the same rate as a year earlier, Colorado maintained its position
as the second largest fluorspar-producing State in the United States. 
 In 1972, the mining industry operated at normal levels. The acid-spar market
soft- 
ened in the last quarter, but the metspar-market remained strong. New mines
opened in Illinois, Texas, and Arizona, but no shipments were reported from
two mines in Arizona, three mines in Utah, or from one mine each in Nevada,
Idaho, and Kentucky. In 1972, 12 companies operated 24 mines in Arizona,
Colorado, Illinois, Kentucky, Montana, New Mexico, Nevada, Texas, and Utah.
Fluorspar ores were concentrated in 15 heavy-media and/or flotation plants.
Employment totaled approximately 1,200 men. Fluorspar shipments were valued
at over $17 million.
