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 This is an electrolytic process, How an Aluminum Smelter is Made - The Aluminum Smelting ,An aluminum smelter includes the potroom, one or more large buildings housing the electrolysis cells, plus a series of other sub-plants that: produces the rodded anodes for the cells, produces compressed air, delivers the alumina to the cells, treats the fluoride gases escaping from the crust, rectifies the alternate current to produce a suitable low voltage high amperage direct current for process flow aluminium smelting plant - educationcare,The Aluminum Smelting Process and Innovative Alternative May 8, 2014 AN ALUMINUM PRODUCTION PLANT (SMELTER) Figure 3 shows a flow sheet of the industrial aluminum production process
