Get Price· The normal production route taken is to refine the bauxite to aluminium oxide, or alumina [Al2O3], which is a white, crystalline powder. This powder is then smelted to form aluminium metal. As a general rule, four tonnes of dried bauxite is required to produce two tonnes of alumina, which in turn provides one tonne of primary aluminium metal.
