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

Mining and Refining Process

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.

Bauxite South32

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.
