Bauxite mining in the United States Wikipedia
Bauxite is the only commercial ore of aluminium, and 96 percent of bauxite consumed in the US is used to produce aluminum (metallurgical grade). However, since 1981, none of the bauxite mined in the US was used to make metallic aluminium. US bauxite is instead used for abrasives, high-temperature refractory materials, and as a high-strength proppant for hydraulic fracturing of oil and gas wells.
