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.
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.
Aluminium is the most abundant material in the Earth's crust and the third most Abundant in all of the Elements after Oxygen and silicon.
The Bauxite is found in a layer of three to four metres deep on average, beneath about half a metre of topsoil.

In the electrical sector aluminium is used In the form of wire, normally reinforced with steel to form cables.
The Economic and environmental benefits of Aluminium
Aluminium is a metal which can easily and economically recycled, by melting it down and casting new products.
Recycled aluminium is known as secondary aluminium. Recycling aluminium uses only 5% of the energy needed...
