When it is melted the Al3+ and O 2- ions are free to move and conduct electricity. Electrolysis of  Apr 9, 2016 Aluminium is extracted from pure aluminium oxide by electrolysis: Aluminium's ore is bauxite, which is purified to give aluminium oxide It has a  The reaction between the two elements in an electrolytic cell is a reduction- oxidation -- or redox -- reaction.

/**/ At the cathode: Here the aluminium ions receive electrons to become atoms again: At the anode: The oxide ions lose electrons to become oxygen molecules, O2: Uses of aluminium: 1. 1821 – Lithium was discovered by the English chemist William Thomas Brande, who obtained it by electrolysis of lithium oxide. 1834 – Michael Faraday published his two laws of electrolysis , provided a mathematical explanation for them, and introduced terminology such as electrode, electrolyte, anode, cathode, anion, and cation. The bauxite is purified to yield a white powder, aluminium oxide, from which aluminium can be extracted. The extraction is done by electrolysis. But first the aluminium oxide must be made molten so that electricity can pass through it.
