Abstract: The present invention relates generally to a method of extracting cobalt and other impurity metals from a concentrated nickel sulphate solution by a solvent extraction process whereby a cationic solvent extractant is separately pre-equilibrated with a portion of a purified nickel sulphate solution in such a manner that it is loaded with nickel without precipitating insoluble nickel double salts. The nickel loaded extracted is then transferred to an impure cobalt nickel solution where the cobalt and certain other impurity metals exchange with nickel leaving a purified concentrated nickel sulphate solution suitable for hydrogen reduction or electrowinning. The cobalt loaded extractant is stripped with dilute sulphuric acid before being recycled while an aqueous cobalt stripped solution is further processed to recover cobalt.

Abstract: The present invention relates generally to a two step solvent extraction circuit to remove impurity metals of zinc and cobalt selectively from a valuable metal of nickel. In order to selectively extract zinc there must be sufficient separation between zinc and cobalt in the cyanex 272 system. Similarly for cobalt and nickel, the separation factor must be of sufficient magnitude to obtain a pure nickel product. The process for the solvent extraction of impurity metals is operated at a temperature exceeding 60° C. being the maximum temperature at which solvent extraction circuits conventionally operate.
