WebAn electrical current is run through the mixture, causing the carbon from the carbon anode to attach to the oxygen component in the alumina, yielding aluminum and carbon dioxide: 2 Al2O3 + 3 C > 4 Al + 3 CO2. This process takes place at temperatures between 940-980º C and yields an aluminum of high purity.
