METODO PARA LA SEPARCION DE NIQUEL-COBALTO
A method is provided for separating nickel and cobalt from a cobalt-nickel precipitate, the cobalt being in the cobaltic state. The method comprises dissolving the precipitate in an ammonium sulfate solution containing NH3, acidifying the solution to a pH of about 1.5 to 3.0 and then cooling the sol...

| description | A method is provided for separating nickel and cobalt from a cobalt-nickel precipitate, the cobalt being in the cobaltic state. The method comprises dissolving the precipitate in an ammonium sulfate solution containing NH3, acidifying the solution to a pH of about 1.5 to 3.0 and then cooling the solution to produce a nickel-ammonium sulfate precipitate highly enriched in nickel. The precipitate is separated from the solution and the solution passed through an ion exchange column selective to the removal of nickel, the solution remaining containing said cobalt substantially free of nickel, the cobalt solution being then sent to cobalt recovery. |
