aluminium production process

How aluminium is produced

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 oxide is broken down into its components using

Production process - European Aluminium

Alumina production. Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called “bauxite residue”, followed by a calcination step which removes the water content in the hydroxide.

Chapter 2. Production and Processing of Aluminum

Throughout the world, primary aluminum is still produced by the electrolysis of alu-mina in molten fluoride salt. This is, in essence, the process that Hall and Héroult in-vented, and which is named after them, but its efficiency has been significantly improved over the years. The electrolysis plant—the aluminum smelter—needs large amounts of
