Bauxite recoveries in modern washing plants is in the range of 60–80%, however, in some of the plants, the recovery is found to be as low as 50%, as they use simple vibrating screens in place of hydro-cyclones. The quality of input bauxite, particularly silica content and targeted washed bauxite quality, dictate the washed ore recovery.
Bauxite mining in the United States
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 ...
