WhatsAppGet PriceGet A QuoteThe 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.
WhatsAppGet PriceGet A QuoteALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
