Aluminum is manufactured through two phases- the Bayer process and the Hall-Heroult process. Aluminum originates from bauxite ore to obtain aluminum oxide. By refining and smelting, the aluminum oxide then releases pure aluminum. A white powder from which aluminum can be extracted. The extraction is done by electrolysis. During electrolysis- positively charged aluminum ions gain electrons and form molten aluminum from the cathode, and oxide ions lose electrons and form oxygen molecules at the anode.
