Bauxite

The total process yield is about 25%: 1 tonne of aluminum is produced by 4.1 tonnes of bauxite. Bauxite extraction levels were 140 million tonnes in 2002, therefore the metal production from primary ore was about 35 million tonnes in the same year. The consumption in Europe in 2002 was 10.2 tonnes, 35% of which came from recycled aluminum.
