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.
The Aluminum Smelting Process Explained | HARBOR
Aluminum smelting consists of extracting bauxite through a two-step process. Learn about the smelting process and the benefit of establishing a network.
Aluminum processing - Smelting, Refining, Alloying | Britannica
In a modern smelter, alumina is dissolved in reduction pots—deep, rectangular steel shells lined with carbon—that are filled with a molten electrolyte consisting mostly of a compound of sodium, aluminum, and fluorine called cryolite.
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.
What Is Aluminum Smelting? - Clinton Aluminum
The process by which the aluminum is extracted from bauxite is known as smelting. What Is The Bayer Process? The process of converting bauxite to pure aluminum typically involves two distinct steps.

Aluminum processing | History, Mining, Refining, & Facts
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 …
Production of Aluminum: The Hall-Héroult Process
A powerful electric current, which is passed through the bath, separates aluminum metal from the chemical solution and the metal is siphoned off. Smelting is the industrial-scale version of the process developed in 1886 by Charles Martin Hall in his woodshed laboratory.
