Bauxite an overview ScienceDirect Topics

Bauxite is an aluminium ore and is recognised as one of the main sources of aluminium. It typically contains different minerals such as boehmite (γ-AlO(OH)), gibbsite (Al(OH) 3 ) and diaspore (α-AlO(OH)) mixed with the kaolinite, goethite, hematite, and minor amounts of anatase (TiO 2 ) and ilmenite (FeTiO 3 or FeO.TiO 2 ) ( Liu et al., 2011 ).

Bauxite an overview ScienceDirect Topics

Bauxite is used in chemical industry, refractory brocks, abrasive, cement, steel, and petroleum. Lateritic bauxite is often used as a building material. The calcined bauxite, produced by sintering of high-alumina in rotary, round or shaft kilns at high temperature, is used as an anti-skid road aggregate which is used in selected areas to prevent road accidents.
