Bauxite Mining Processing. Bauxite is the principal ore of alumina Al2O3, which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30 of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden.
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 worlds largest producer of ...
