Aluminium is a light metal used for making a large number of things we see and use every day. They range from Aeroplanes to soft drink cans. Aluminium is the most common metal found in the Earth's soil.
Bauxite
The first step in the production of Aluminium is to mine the ore, which is called Bauxite. Bauxite is formed by the natural weathering of sedimentary rocks which contain a high proportion of Aluminium- bearing minerals.
