Bauxite ore contains sufficiently high levels of aluminium oxides and suitably low levels of iron oxide (Fe 2 O 3) and silica (SiO 2) to be economically mineable. The amount of reactive silica is particularly important as this form of silica consumes the caustic soda needed to make alumina, thus low reactive silica is desirable. The first step in producing aluminum is mining its ore bauxite. Bauxite occur in tropical and sub tropical areas.Bauxite is the most important ore of aluminum which contains 30 to 54 % of alumina, with the symbol Al2O3, the rest is the silica, iron oxides, titanium, and other impurities in trace amount.
