| Abstract: |
| Lix 84 was used to separate copper, nickel and cobalt from ammoniacal leach liquor of ocean polymetallic nodules. Copper and nickel wer co extracted by Lix 84 leaving cobalt in theraffinate. The selective stripping of nickel and copper with a precise control concentration of acid solution produced solutions rich in these metals while regenerating the solvent for re use. This technique has an advantage in easy operation because of only one solvent bein g used. It can be used intreating ocean polymetallic nodules and other complex ores containing copper, nickel and cobalt. |
