The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

metal on Earth, but it is expensive, largely because of the amount of electricity used in the extraction process. Aluminium ore. is called bauxite (Al 2 O 3).
To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash. This mixture is placed into a digester, where it is heated under steam pressure. Caustic soda is added, which dissolves the alumina from the ore. The other impurities are left as solids. After this, a filter separates the solids from the solution.
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 ...
