How aluminium is produced

The aluminium production process is much more complex and requires huge amounts of electricity. For this reason, aluminium smelters are always built in the vicinity of power energy sources, usually hydroelectric power plants that don't contaminate the environment. But let's start at the beginning.

Aluminum processing - Ores Britannica

Bauxite beds are blasted loose and dug up with power shovel or dragline, and the ore is transported by truck, rail, or conveyor belt to a processing plant, where it is crushed for easier handling. Refining plants are located near mine sites, if possible, since transportation is a major item in bauxite costs.

Alumina Refining The Aluminum Association

Alumina is the common name given to aluminum oxide (Al 2 O 3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process. This process is ...

12.1 Primary Aluminum Production

Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum. The refining and reducing processes are seldom ...
