Aluminium life cycle - Norsk Hydro

Using the Bayer process, alumina (aluminium oxide) is extracted from bauxite in a refinery. The alumina is then used to produce the primary metal at a ratio of 2:1 (2 tonnes of alumina = 1 tonne of aluminium). 3. Primary production. The aluminium atom in alumina is bonded to oxygen and needs to be broken by electrolysis to produce aluminium metal.
