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 …

Bauxite is transported from the mines by rail to Kwinana and by overland conveyor to Pinjarra. The close proximity of mine to refinery lowers operational costs. Bauxite from Huntly is low in alumina grade and low in reactive silica. This results in low consumption of caustic soda, which further reduces production costs.


After the bauxite is mined, it is crushed onsite, before being transported on one of the world's longest overland conveyor systems for 50 kilometres, to the company's alumina refinery, which is situated 15 kilometres from the town of Collie.

Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent-30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is bauxite.


Bauxite was first discovered by a French chemist, P. Berthier, in 1821 while investigating specimens found near Les Baux in southern France. The rock name bauxite was not used until many years later. The development of the Bayer Process for the extraction of alumina from bauxite and the Hall process for the reduction of the alumina to metallic

Metallurgical Bauxite: The metallurgical Bauxite is used for aluminium production. Metallurgical bauxites are sub-divided into two basic types based on the processing methods that must be applied to them at the alumina refinery stage, namely: (i) low temperature gibbsite (tri-hydrate or tropical bauxite) & (ii) high-temperature boehmite (monohydrate or European bauxite).
