Alumina Refining The Australian Aluminium Council

The bauxite residue is safely stored, in ways which meet industry best practice and required safety standards. One technique used for bauxite residue storage in Australia is “dry stacking’”, which involves depositing and drying the residue in thin layers to a high density, thus making it very stable and unlikely to flow in the event of a

How Aluminium is Made The Australian Aluminium Council

Bauxite Mining. Bauxite is the primary ore from which aluminium metal is extracted. Australia has the second largest reserves of bauxite in the world and is currently the world’s largest producer (102 Mt in 2019). Once the bauxite is mined from the surface, the land is rehabilitated.

Mining and Refining – Process - World Aluminium

Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.
