The earlier temperature ion-exchange separation of copper and zinc with temperature variations on Amberlite IRC-718 iminodiacetic resin was physicochemically described. Contrary to conventional double temperature ion-exchange separation methods, the temperature dependence of ion-exchange selectivity was not found to be a main driving force of the process. Separation of the two metals is controlled by formation of HSO{sub 4}{sup {minus}} complexes in the surrounding solution.
