What is Bauxite? Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large scale aluminium production. Although aluminium is the most abundant metallic element in the earths crust constituting about 8%, it usually occurs in clays, soil and rocks that cannot be utilized for its extraction.

Bauxite is the primary source for aluminum (Al). Ores in this group include aluminum hydroxides, gibbsite, boehmite and diaspore. It is not just the concentration of aluminum that is important for bauxite mining, but also the identification of penalty elements such as iron oxide that may also make overall compositional analysis more challenging.
Bauxite, rock largely composed of a mixture of hydrous aluminum oxides.Bauxite is the principal ore of aluminum.. Bauxites vary physically according to the origin and geologic history of their deposits some deposits are soft, easily crushed, and structureless some are hard, dense, and pisolitic, or pealike still others are porous but strong or are stratified or largely pseudomorphic after ...
The bauxite mines in the Darling Range have the worlds lowest grade bauxite ore mined on a commercial scale (around 27-30% Al 2 O 3). Despite the low grade, the mines accounted for 23% of global alumina production. JORC-compliant bauxite resources also occur in New South Wales and Tasmania but these are small (25 Mt).
