| Abstract: | A purification process for cobalt electrolyte has been proposed. In this process Fe, Zn and Mn were re-moved by P204, Cu and Ni were removed by HA - PE206. The bench-scale test and pilot test were carriedout in several centrifugal contactors. The refined cobalt chloride liquor met a criterion of l# cobaltelectrolyte (Co - 100g/L),Fe<0.001g/L, Zn<0.001g/L, Cu<0.0003g/L and Ni<0.03g/L) and 1# cobalt productwas obtained. |
