Bauxite - Wikipedia

Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.


Ore Concentration The lead-rich ore, with a typical concentration range of 3-8% lead, must first be separated from other material (the gangue). The principle of using flowing water to wash away the lighter gangue particles, leaving the denser ore behind, has also been used since ancient times (e.g. Laurium, Greece, 5th century BC. Healy, 1978,
