How is aluminum smelted

An aluminium smelter consists of a large number of cells (pots) in which the electrolysis takes place. A typical smelter contains anywhere from 300 to 720 pots, each of which produces about a ton of aluminium a day, though the largest proposed smelters are up to five times that capacity. Meer weergeven 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 Meer weergeven The Hall-Héroult electrolysis process is the major production route for primary aluminium. An electrolytic cell is made of a steel shell … Meer weergeven Electrolyte: The electrolyte is a molten bath of cryolite (Na3AlF6) and dissolved alumina.
