Bauxite ore is a mixture of hydrated aluminium oxides and compounds of other elements such as iron. The aluminium compounds in the bauxite may be present as gibbsite 2(Al(OH)3), böhmite (γ AlO(OH)) or diaspore (α AlO(OH)); the different forms of the aluminium component and the impurities dictate the extraction conditions.

Bauxite is either pale pink, orange, or reddish rock, which often contains rounded concretionary masses of aluminum hydroxides and iron (hydr)oxides. These are known as pisoliths. They resemble ooids, but are generally less regular in shape, although their genesis is similar — there is a nucleus around which mineral matter started to accumulate.
