Aluminium production process

ALUMINA 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

ore
