Aluminium Ore: Extraction of Aluminium

Dressing or concentration of the bauxite ore– Bauxite is generally found as an impure form of aluminium oxide. The process which gives the ore such a physical form so that the gauge can be easily removed from it, is called dressing of the ore. It is done by hand – picking, grinding etc. Bauxite ore generally contains ferric oxide and silica as impurities. Dressing of bauxite ore is done by ...

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) 4) and small ...
