Extraction of Aluminium from Bauxite
Extraction of Aluminium from Bauxite. Aluminium is a reactive metal, above carbon in the reactivity series. Its main ore, is bauxite, which contains aluminium oxide. Aluminium is higher in the reactivity series than carbon, so it cannot be extracted by reduction using carbon. Instead, aluminium is extracted by electrolysis.

Extraction of Metals
Reduction with carbon normally involves heating the metal oxide in the presence of the carbon, which is often used in the form of coal. Most metals are only found as compounds because the metal has reacted with other elements in the past. Because of this, the metal has to be extracted from the ore (rock) where the metal compound is found.
