Increasing Aluminum production purity in reduction cells

Aluminium is extracted from alumina through an electrolytic reduction process . The purity of raw materials are crucial and effective on purity of reduction cells. The main raw material for aluminium production is as follow:Alumina, anode, cryolite , aluminium fluoride , additives and modifiers .Typically the purity of aluminium production in reduction cells in aluminium metal, the impurity of Fe 0.09% and Si 0.04% is visible.By performing simple equation we can see the impurity of metal is higher than raw material impurity in the process.As result ,the impurities from other sources are most effective in the quality of the metal.This article is studied the ways of impurities in pot and the ways of controlling them.
