    Hydraulic WashingMagnetic SeparationFroth Flotation ProcessLeachingBayer ProcessThe leaching of aluminium from its core bauxite on an industrial scale is known as the Bayer process. This process will give us the end product of Alumina (aluminium oxide) from bauxite. The other impurities of silica, titanium oxide and varies other oxides will separate. The first step is to heat the bauxite ore to temperatures of 200°c along with a sodium hydroxide solution. This will convert the aluminium oxide to a solution of sodium aluminate. The silica will dissolve itself in the process. The chemical equation is Al2
