Minerals Yearbook, 1992: Wyoming
Wyoming nonfuel mineral producers reported a 1992 value of production of $951 million, a 2% increase from that of 1991. Gains in the production value of portland cement, bentonite clay, gypsum, soda ash, and crushed stone more than offset declines in the value of common clay, gemstones, Grade-A helium, lime, and construction sand and gravel. Nationally, Wyoming ranked 10th in nonfuel mineral productions value, accounting for about 3% of the U.S. total. Wyoming continued to be the Nation's leading producer of bentonite clay and soda ash, and the second largest producer of total clays and Grade-A helium.
