How Aluminium is Made

The Process


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 (96 Mt in 2018). Once the bauxite is mined from the surface, the land is rehabilitated.

Alumina Refining

Alumina refineries process bauxite ore to produce alumina, which is then used to extract aluminium metal. Australia is the second largest producer of alumina in the world (20.3 Mt in 2018).

Aluminium Smelting

Aluminium smelters use an electrolytic process to extract aluminium metal from alumina.
Australia is currently the sixth largest producer of primary aluminium (1.58 Mt in 2018).
