Minerals Yearbook, 1993: Aluminum, Bauxite, and Alumina

摘要

Domestic primary aluminum production decreased significantly in 1993 to itslowest level in 6 years. Thirteen companies operated twenty-two primary aluminum reduction plants and 1 plant remained temporarily closed. Montana, Oregon, and Washington accounted for 34% of the production; Kentucky, North Carolina, South Carolina, and Tennessee, 22%; and other States, 44%. The value of primary metal produced domestically in 1993 was estimated at $4.3 billion. In response to rising world inventories and depressed prices, more than one-half of the domestic primary aluminum smelters announced temporary shutdowns in production capacity during the year.
