OSTI ID:6016616
The report has been prepared under a Memorandum of Understanding between the U.S. Bureau of Mines, U.S. Department of the Interior, and the California Department of Conservation, Division of Mines and Geology, for collecting information on all nonfuel minerals. California ranked second among the States, after Arizona, in the value of nonfuel minerals produced in 1991, accounting for almost 10% of the U.S. total. The value of the commodities produced during the year decreased about 9% to $2.5 billion, following last year's 4% decline. California was the sole producer of boron and tungsten and led all States in the production of asbestos, portland cement, diatomite, calcined gypsum, rare-earth concentrates, and construction sand and gravel. It was second in natural calcium chloride, gold, magnesium compounds, pumice, industrial sand and gravel, and soda ash.
