of bauxite being shipped from Weipa. Why mine bauxite? The mining process is the first step in the production of aluminium. Bauxite ore is found in a layer up to four metres deep in the form of small red pebbles called pisolites. Bauxite is processed into a white powder called alumina, which is then processed at smelters into aluminium.

Bauxite is an aluminium ore found in deposits around the world. Once the ore is mined out of the ground, the red bauxite rock is crushed and dissolved into a white alumina powder, using what is known as the Bayer process. This alumina powder is then smelted into aluminium metal. Australia is the world's largest producers of bauxite.
