Typical deposits range in thickness from 3 to 15 m. The majority of the bauxite can be mined and processed without beneficiation (further treatment of the ore to concentrate the minerals), but the ore in the north of Brazil and in Vietnam has a high clay content and has to be washed before processing.

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

The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue. The aluminate solution is then decomposed producing Al (OH)3

Processing of Bauxite Ore. Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite. From here, the ore is digested in a heated, pressurized vessel at temperatures
