Todays alumina and bauxite producer is constantly challenged to improve safety, profitability, efficiency, and product quality while helping to sustain the surrounding environmental resources. water plays a critical role in virtually all mining and mineral processing activities.
Bauxite beds are blasted loose and dug up with power shovel or dragline, and the ore is transported by truck, rail, or conveyor belt to a processing plant, where it is crushed for easier handling. refining plants are located near mine sites, if possible, since transportation is a major item in bauxite costs.

Mined bauxite ore is refined into alumina, through what is known as the bayer process. the bayer process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process.
The bauxite residue is safely stored, in ways which meet industry best practice and required safety standards. one technique used for bauxite residue storage in australia is dry stacking, which involves depositing and drying the residue in thin layers to a high density, thus making it very stable and unlikely to flow in the event of a ...
