How aluminium is produced

Bauxite Mining. The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium …

Extraction Process of Aluminium from Bauxite Ore

2016-4-11 · Aluminum is the most abundant metal in the earth''s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.. Bauxite is the general name given to the hydrated oxides of aluminum.
