MINERAL PROCESSING TECHNOLOGIES IN THE BAUXITE AND ALUMINA INDUSTRY

Buntenbach S

The Bauxite and Alumina Industry is facing some important challenges to improve the process chain for the production of aluminium. The process chain has to be improved from the bauxite mining and processing up to the refinery and smelter process.

Up-to-date technologies of mineral processing, like

Washing and Elutriation
Separation of Fines
Gravity Separation
Magnetic Separation

are able to contribute to the beneficiation of ROM (Run of Mine) Bauxite to increase the Al2O3 content of the ore, the Al203/ SiO2 ratio, or even the content of Fe+.
