Aluminum production plants typically use the Hall-Héroult process, which involves extracting aluminum from its oxide, alumina. The process involves the following steps:

Bauxite ore is first mined and then processed into alumina through the Bayer process.

The alumina is then smelted using the Hall-Héroult process, which involves passing a large electrical current through a molten mixture of alumina and cryolite (a type of fluoride mineral).

The electrical current causes the aluminum ions to be reduced and deposited onto a cathode, while oxygen is released at the anode.

The aluminum that is deposited onto the cathode is then extracted and processed further into products such as ingots, billets, or rolls.

Aluminum production plants also typically use a variety of other equipment and processes, including crushers, conveyors, grinders, digesters, and casting machines.
