The Global Aluminium Industry 40 years from 1972

Today, the global aluminium industry has only a bare resemblance to what it was in the early 1970s. The most important structural changes are the geographical relocation of bauxite, alumina and aluminium production centres; shifts in the degree of concentration and integration; the emergence of new consuming regions, the development of new end-use

aluminium (US: aluminum)

The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite - another aluminium compound. The aluminium oxide has too high a melting point to electrolyse on its own. Aluminium ore. The usual aluminium ore is bauxite. Bauxite is essentially an impure aluminium oxide.

Extraction Process of Aluminium from Bauxite Ore

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.
