Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.

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 5 (OH) 4) and small

Bauxite is collected from the ground in an open-pit mining operation. It doesn’t sit very deeply in the earth’s crust, so some energy can be saved on drilling. However, to recover all the aluminum in an area, swaths of land must be bull-dozed to reveal the dirt and ore underneath. Once collected, the bauxite ore has to be refined

The IAI was established in 1972 primarily to collect and publish statistical data – and this remains one of our major functions. IAI membership represents over 60% of global bauxite, alumina and aluminium production. 75% of all the aluminium ever produced is still in productive use, having been through countless loops of its lifecycle.

The EC also concludes that European demand for both primary aluminium and bauxite will increase by 2050 and indicates the risk of destabilization generated by Chinese appetite in these markets. Despite a 12-fold increase in its mining production since 1995, China now absorbs two-thirds of global bauxite imports (OECD, 2019).
