Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium. The principal minerals in bauxite are gibbsite (Al 2 O 3 .3H 2 O), boehmite (Al 2 O 3 .H 2 O) and diaspore, which has the same composition as boehmite, but is denser and harder. Australia is the world's largest producer of ...
