Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world& 39;s main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. In 1821 the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France.
