Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small ...

Extraction Process of Aluminium from Bauxite Ore

Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum. It contains varying amounts of ...

Aluminium life cycle

11-3-2019· Using the Bayer process, alumina (aluminium oxide) is extracted from bauxite in a refinery. The alumina is then used to produce the primary metal at a ratio of 2:1 (2 tonnes of alumina = 1 tonne of aluminium). 3. Primary production. The aluminium atom in alumina is bonded to oxygen and needs to be broken by electrolysis to produce aluminium metal.
