Aluminium smelting - Wikipedia
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.
Aluminum processing - Smelting, Refining, Alloying | Britannica
The smelting process is continuous. Additional alumina is added to the bath periodically to replace that consumed by reduction. Heat generated by the electric current maintains the bath in a molten condition so that fresh alumina dissolves. Periodically, molten aluminum is siphoned off.

Aluminum processing, preparation of the ore for use in various products. In addition to its low density, many of the applications of aluminum and its alloys are based on its high electrical and thermal conductivity, high reflectivity, and resistance …
Hall–Héroult process - Wikipedia
The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell.

Aluminum smelting consists of extracting bauxite through a two-step process. Learn about the smelting process and the benefit of establishing a network.
Smelting - Wikipedia
Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc.
Production of Aluminum: The Hall-Héroult Process
Step 3: Smelting into aluminum An electrolytic reduction process known as smelting dissolves the alumina in a cryolite bath inside carbon-lined cells, or pots. A powerful electric current, which is passed through the bath, separates aluminum metal …
