Bauxite is the most important ore of aluminum which contains only 30–54% alumina, Al2O3; the rest is a mixture of silica, various iron oxides, and titanium dioxide along with trace amounts of zinc, phosphorous, nickel, vanadium etc., as indicated earlier.

Bauxite deposits are formed chiefly by weathering of aluminous rock; some have been transported to their present locations, but most are residual accumulations from which most other constituents of the parent rock, other than alumina, have been leached.

The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. The most common aluminum-bearing minerals in bauxite are gibbsite (AlOH3), boehmite (AlO(OH)), and diaspore (AlO(OH)).

Definition of ore grade and classification of the bauxite products depends on their overall chemistry, therefore resource models of the bauxite deposits need to accurately reproduce the vertical profiles of Al 2 O 3 and SiO 2. This is usually achieved by applying a special unfolding algorithm, referred to as the 'equal thickness unfolding ...
