In fact, it is the most abundant metal on the earth’s crust. However, it is rarely found in its pure form naturally. The chief source of aluminium is bauxite ore, which was discovered in 1821 by P. Berthier. He found a hard, reddish, clay-like material (one that contained 52% aluminium oxide) near the village of Les Baux in southern France. Berthier named it bauxite after the village.

Years later in 1886, Charles Martin Hall made a discovery in Ohio. At the same time, metallurgist Paul Louis Toussaint Héroult made the same discovery in Gentilly. Both men dissolved aluminium oxide in molten Cryolite and extracted the aluminium through electrolysis. This came to be known as the Hall-Héroult electrolytic method and was economically viable too.
