Aluminum refining The crude aluminum electrowinned by the crude-Elu method is mixed with impurities such as silicon, iron, and titanium from the molten bath material and the electrode ash. The upper limit of the purity is only about 99.8%. Therefore, if higher purity is required, copper is added to aluminum to make a low melting point, high density alloy anode with 33% Cu, which has a higher density electrolyte than pure aluminum, and an upper cathode. Between the electrolysis, precipitation of fine aluminum. This is a three-layer molten salt electrolysis refining method. This method can also be used when aluminum is recycled from aluminum scrap.
