Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived.
Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the socalled "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.

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.
