Bauxite - Wikipedia
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the worlds 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 ...
Aluminium life cycle
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.
