Raw Bauxite. Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al (OH)3, Boehmite g-AlO (OH) and ...

view moreAn experimental study of a sample of low-quality bauxites showed a significant differentiation in the chemical composition of the separated granulometric fractions of the base bauxite. It is shown that additional changes in the composition of fractions occur in the process of dry and wet grinding of bauxite.
