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,Bauxite: The principal ore of aluminum. - Geology,In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of aluminum hydroxide, Al(OH) 3. The aluminum hydroxide is then calcined to form alumina, Al 2 O 3. Aluminum is smelted from the alumina using the Hall-Heroult Process.List of alumina refineries - Wikipedia,Bauxite and Alumina, United States Geological Survey; Hydro Aluminium, (2004).
