How aluminium is produced

Bauxite Mining. The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium

Chapter 2. Production and Processing of Aluminum

1999-5-7 · The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.
