Bauxite | Geoscience Australia

31.12.2016· 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). Australia is the world's largest producer of bauxite

Extraction Process of Aluminium from Bauxite Ore

11.04.2016· Bauxite is the general name given to the hydrated oxides of aluminum. It contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum
