Bauxite

Bauxite

Bauxite is the most important aluminium ore. It consists largely of the minerals gibbsite Al(OH) 3, boehmite γAlO(OH), and diaspore αAlO(OH), together with the iron oxides goethite and hematite, the clay mineral kaolinite and small amounts of anatase TiO was named after the village Les BauxdeProvence in southern France, where it was first discovered in 1821 by geologist Pierre Berthier.

Chapter 2. Production and Processing of Aluminum

Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining loions 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.
