What is the extraction process of Aluminium?

Aluminum is extracted from aluminum oxide by a process called electrolysis. First of all, aluminum oxide needs to be in molten form to extract the aluminum ions. The steel case, used in electrolysis, is coated by graphite. The positive anodes are also made of graphite but are immersed in the molten cryolite solution.

Aluminum Extraction - an overview ScienceDirect Topics

In the electrolytic extraction of aluminium, the anodic process is the discharge (or oxidation) of the oxide ion, O 2−. The net process is the decomposition of the feed alumina, Al 2 O 3, into aluminium metal and oxygen, which in turn reacts with the carbon (anode) to produce CO 2 at elevated working temperatures (e.g. 900 °C). The process ...
