Aluminum Smelting Furnaces and Processing of Bauxite Ore ...
· The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed .
What Are Bauxite Tailings Or Red Mud?
· Bauxite tailings are produced during the Bayer Process which is the most commonly used method of refining bauxite to aluminum oxide. Estimates indied that roughly 95% of the aluminum oxide produced in the world was made through the Bayer Process. After the bauxite ore is extracted from mines, it is taken to a plant where it is refined.

Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O .
