The process for removing impurities, in particular for removing sodium chloride from aluminum melts, employs reactive chlorine which is introduced into the melt and then passes with the melt through a filter bed. Aluminum chloride formed by the reaction of the chlorine with the melt is chemisorbed on the chloride or group of alkali or alkali earth chlorides in the filter and the sodium in solution in the melt is in turn chemisorbed on the aluminum chloride thus reducing the sodium content of the melt. |
