    Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived. The respective processes take place in an alumina refinery and aluminium smelter, which may or may not be integrated.

    Extraction Process of Aluminium from Bauxite Ore

    Aluminum is the most abundant metal in the earths 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.

    In the bauxite refining process, the aluminumbearing minerals in bauxite are converted in a multiplestep process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line hightemperature rotary kilns and metallurgical furnaces.
