Aluminium production process

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. The sodium aluminate solution is stirred in precipitators for several days, eventually pure alumina or Al 2 O 3 settles at the bottom

Aluminum | Minerals Eduion Coalition

Aluminum is the most abundant metal element in the Earth’s crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.
