20/02/2020 The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted.The extraction is done by electrolysis. positively charged aluminium ions gain electrons from the cathode, and form molten aluminium. oxide ions lose electrons at the anode, and form oxygen molecules.

GCSE CHEMISTRY Extraction of Aluminium Electrolysis

Extraction of Metals. Extraction of Aluminium. Aluminium ore is called bauxite. Bauxite contains aluminium oxide, water, iron oxide and other impurities. The purified dry ore, called alumina, is aluminium oxide Al 2 O 3. The alumina must be molten for electrolysis to work, since the ions are not free to move in the solid state. Unfortunately, alumina has a high melting point (2040 °C) and
