Bauxite/aluminous soil nature : including Gibbsite Shek, a diaspore, a water boehmite, hematite, kaolinite, opal and other minerals mix, composition changed greatly. General bauxite containing Al2O340.0% -75.0%, which often contain trace gallium. Usually in dense block, Wilson, the oolitic and earthy as collectivities. The color compositions which, usually white, gray, restless, yellow-green, pink, brown, etc.. Matt. Hardness 1-3. Density 2-3. Gibbsite from which (gibbsite), also known as the aluminum water of oxygen stone components for the Al (OH) 3, monoclinic, usually Species Flake collectivity; A Diaspor (diaspore; Empholite) also known as hard water with aluminum components α - AIO (OH), the regular - Fe, Mn, rhomboidal, sustained Species Flake collectivities hardness (6-7); a water boehmite (boehmite), also known as the mixing aluminum components γ - AlO (OH), the rhomboidal appearing Aphanitic block or colloidal. Bauxite mentioned can be used to manufacture refractories and aluminum, alumina cement, artificial corundum and various aluminum compounds.
