en.wikipedia.org/wiki/Aluminium_smeltingIt involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell.
en.wikipedia.org/wiki/Hall%E2%80%93H%C3%A9r…The extraction of aluminum from its ore and subsequent processing into finished prod- ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites.

The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process applied at industrial scale happens at 940–980 °C (1700 to 1800°F) and produces 99.5–99.8% pure aluminium. Recycling aluminum requires no ele…
