Aluminum Extraction
Bauxite, the main ore of aluminium, is converted to aluminium oxide (alumina) via the Bayer Process. The alumina is then converted to aluminium metal using electrolytic cells and the Hall–Heroult process. Since the HallHeroult electrolytic process requires an enormous amount of energy, most of the aluminium extraction plants are loed where energy is cheaper. .
