Extraction of Aluminium
Extraction of Aluminium. Aluminium has a lower density than other common metals, about one-third that of steel. When exposed to air, it forms a protective layer of oxide on the surface due to its high affinity for oxygen. Aluminium resembles silver in appearance, both in colour and in its ability to reflect light.
