Bauxite

It is also known as aluminium ore and usually obtained from open cast mines. Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. Approximately 70% to 80% of the world's dry bauxite production is processed first into alumina, and then into aluminium by electrolysis as of

Case Study: Conversion of Bauxite Ore to Aluminum Metal

Bauxite Ore Processing. Aluminum is found in varying amounts in nature as aluminosilicates (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 3.xH 2 O, known as bauxite. The bauxite is purified by the Bayer Process.

Industrial Minerals

Bauxite is the primary source of aluminium metal, and about 85% of bauxite mined is processed via the Bayer Process to make alumina trihydrate (ATH), then smelter grade alumina (SGA) from which aluminium metal is derived. The respective processes take place in an alumina refinery and aluminium smelter, which may or may not be integrated.
