Bauxite

Bauxite is an ore which contains iron, titanium and gallium compounds in addition to aluminium silicates. The chemical bonds cannot be separated from each other by simple melting. Because the aluminium cannot be melted out, the unwanted substances are separated out chemically with caustic soda. The silicate is then burnt, forming aluminium oxide.
