The Transformation of Bauxite to Aluminum (and the Products in Between)
An 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.
