Bauxite is an impure form of alumina aluminium oxide. Bauxite ore contains impurities like ferric oxide and silica. Bauxite ore is crushed and pulverized first. The impurities like ferric oxide are removed by magnetic separation. The bauxite ore is then concentrated by Hall's process. The steps involved in bauxite ore are as follows:
