Bauxite mining in the jarrah forest of southwestern Australia occurs on land subject to multiple use. Techniques for the reestablishment of a variety of ground covers based on native and introduced species have therefore been developed. Shallow mining of stered ore bodies 2 to 100 ha in area allows close integration of rehabilitation with mining.

DRY BENEFICIATION OF BAUXITE MINERALS USING A TRIBO ...

Bauxite mining of both metallurgical and nonmetallurgical grade ores is analogous to the mining of other industrial minerals. Normally, the beneficiation or treatment of bauxite is limited to crushing, sieving, washing, and drying of the crude ore [3]. Flotation has been employed for the upgrading of certain lowgrade bauxite ores, however it has not proven highly selective at rejecting ...
