The name bauxite is applied to earthy deposits and rock principally composed of one or more hydrated aluminum oxide mineral species. Bauxite contains a large number of impurities such as silica, iron and titanium oxides, and various other elements mostly in minor or trace amounts.
There are four basic grades of bauxite- Chemical grade- (55-58% min. pure), Abrasive grade- (55% min. pure), Refractory grade- (59-61% min. pure) and Metallurgical grade- (50-55% min. pure). Bauxites are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical and refractory.
