ARIZONA—1990 73THE MINERAL INDUSTRY OF ARIZONA This chapter has been prepared under a Memorandum of Understanding between the Bureau of Mines, U.S. Department of the Interior, and the Arizona Department of Mines and Mineral Resources for collecting information on all nonfuel minerals. By Michael N. Greeley' and Leroy E. Kissinger2 Arizona mines led the United States in the production of nonfuel minerals in 1990. The total value of output, nearly $3. 1 billion, increased about 1 % over that of the previous year. The State led the Nation in copper production and was also among the top producers of gem stones, lime, molybdenum, rhenium, sand and gravel, silver, and sulfuric acid. Nearly onequarter of the value of all metals produced in the United States in 1990 was attributed to the mines of Arizona. In terms of value, therefore, the State I was the country's leading producer of ~ metals. Metal output valued at $2. 82 billion I I represented more than 92 % of all nonfuel - mineral production in the State. - ~ Industrial mineral production for the year was $243 million or about 8 % of the total ~ mineral value in Arizona. ~ TRENDS AND - DEVELOPMEMS The mineral industry of Arizona exhibited a mixed character in 1990. A slight increase in the total value of nonfuel mineral production was primarily due to increased output of the two metals: copper and gold. Unit prices of essentially all the metals produced in the State declined substantially. The value of industrial mineral production during the year fell markedly to almost 16% less than that of 1989. Although some gains in output were registered, chiefly in gypsum and lime, most commodities produced for the construction industry such as aggregates, common clays, and sand and gravel TABLE 1 NONFUEL MINERAL PRODUCTION IN ARIZONA1 Mineral 1988 1989 1990 .
