  • mining waste generated from aluminium production grid

    The production of aluminium involves three main stages:mining bauxite ore,refining bauxite to alumina (Al2O3), and then smelting alumina to produce aluminium. Bauxite comes from open mines mainly located in tropical and subtropical regions. On average it takes 4 to 5 tonnes of bauxite to produce 2 tonnes of alumina, yielding 1 tonne of aluminium

  • aluminium production process

    ALUMINA PRODUCTION.Bauxiteis 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
