How Aluminum is Produced

Aluminium is the third most abundant element in the Earth's crust, but does not occur as a metal naturally. The first step in producing aluminium is mining its ore – bauxite.Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits located in Europe.
