  • FACT SHEET #2 Bauxite

    Primary aluminium is made from an ore called bauxite, which is refined to make alumina before being smelted to make aluminium. It takes 4-6 tonnes of bauxite (depending on the quality) to make ~2 tonnes of alumina, which then makes 1 tonne of aluminium. Australia is the world's largest producer of bauxite.

  • Aluminum Ore

    Bauxite is an aluminium ore and is recognised as one of the main sources of aluminium. It typically contains different minerals such as boehmite (γ-AlO (OH)), gibbsite (Al (OH) 3) and diaspore (α-AlO (OH)) mixed with the kaolinite, goethite, hematite, and minor amounts of anatase (TiO 2) and ilmenite (FeTiO 3 or FeO.TiO 2) ( Liu et al., 2011 ).

    The ultimate product of calcination is the most stable phase of alumina, corundum or -alumina. This is, however, not desirable for smelting, because -alumina is slow to dissolve in the bath (refer to Section 24). For the formation of Smelting Grade Alumina (SGA), calcination is carried out at around 950°C.
