Industrial Minerals Of Nevada

Nevada is especially well endowed with industrial minerals, both in the number of ore deposits and the diversity of commodities. More than 600 significant industrial mineral deposits, containing 22 principal commodities, are present, in the State. The materials produced in Nevada in 1978 had a value of approximately 113 million dollars, and additional processing of some of them (e.g. gypsum into wallboard, limestone and clay into cement) added considerable more value. Table 1 shows the value of Nevada's industrial mineral production in 1978. Nevada currently supplies 85 percent of the country's barite producing 1.6 million tonnes (1.8 million short tons) valued at 30 million dollars in 1978. Nevada is second in diatomite production and contributes one-third of total lithium produced. Other industrial minerals being produced include clays, fluorspar, gypsum, lightweight aggregates, limestone and dolomite, magnesite and brucite, perlite, salt, sand and gravel, and silica. In general, Nevada produces high-value industrial minerals which are not consumed within the State, but rather, are shipped out of State. In contrast, most more populous states produce larger tonnages of lower value industrial minerals which are consumed chiefly within that state.
