Abstract

The process for the electrochemical separation of metal mixtures and metal alloys comprises the steps of dissolving the starting material in an elecrolyte, substituting the metals dissolved in the electrolytic solution in succession in accordance with their electrochemical potential by electrochemically less noble metals in each case and depositing them. The electrolytic solution containing the dissolved metals is passed continuously through several cells, connected to each other, in which the electrolytic solution is brought into contact with said less noble metals. Several of the metals dissolved can be substituted simultaneously by one or more electrochemically less noble metals. Metals that are deposited simultaneously together are separated electrolytically from each other, and metals which have again gone into solution are again substituted outside the electrolysis cells by said less noble metals and deposited.
