Aluminum comprises approximately 8% of the earth's crust, making it second only to silicon (27.7%). Iron is third at about 5%. Metallic aluminum is not found in nature; it occurs in the form of hydrated oxides or silicates (clays). The principal ore from which aluminum is extracted is called bauxite after the town of Les Baux in southern France
