| Abstract: | In a raw nickel hydroxide produced some nickel ore,there are many impurities,such as iron,calcium,magnesium,silicon,copper,zinc,cobalt,etc.After leaching using ammonia,nickel,copper,zinc and cobalt go into solution as metal-complexes.Nickel can be separated from other impurities by solvent extraction using ammonia extractant-striping using sulphuric acid,nickel solution meets with electrodeposition demands can be obtained. |
