The United States remained highly dependent on foreign sources of bauxite in 1990. Almost all of the relatively small domestic mine output was used for nonmetallurgical products, including abrasives, chemicals, proppants, and refractories. Domestic production of bauxite for the year was projected to have been 26 pct less than in 1989. This significant reduction was attributed partly to the permanent closure of the last remaining bauxite mining operation in Arkansas during the second quarter of 1990. In recent years, bauxite has been produced primarily from surface mines in Arkansas, Alabama, and Georgia, with only the latter two states producing and processing refractory-grade product. In 1990, the refractory-grade bauxite mine production from Alabama and Georgia was estimated to have declined by approximately 16 pct, and imports continued to dominate the U.S. market.
