Aluminium production process

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. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud.
