Bauxite Geoscience Australia

Dec 31, 2016  In most commercial operations, alumina is extracted (refined) from bauxite by a wet chemical caustic leach process known as the Bayer process. The alumina is then smelted using the energy-intensive Hall-Heroult process to produce aluminium metal by electrolytic reduction in a molten bath of natural or synthetic cryolite (NaAlF 6 ).

Adopting the process of washing bauxite in the beneficiation plant can reduce caustic soda consumption and equipment and piping scale in the alumina refinery (OPEX), and consequently the payback for the beneficiation plant can be less than 3 (three) years.

Mining and Refining – Process

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.
