Histalu: Aluminium Production: From Bauxite to Alumina
Bauxite contains 40-60% hydrated aluminium oxide mixed with silica and iron oxide. It is the latter that gives bauxite its characteristic red colour. The name "bauxite" comes from the village of Les Baux-de-Provence in Bouches-du-Rhône (France), where the mineralogist Pierre Berthier first analysed the ore in 1821.
