Mining and Refining Bauxite Residue Management

It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 30%), titanium dioxide (2 15%), silicon oxide (5 20%) and undissolved alumina (0 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.

Alumina Refining The Australian Aluminium Council

Aluminium does not occur as a metal but must first be refined from bauxite into alumina. Approximately two tonnes of alumina are required to produce one tonne of aluminium. Australia is the second largest producer of alumina in the world, with around 15 per cent of global production from six alumina refineries.

Bauxite Geoscience Australia

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 bauxite

Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small
