Method of recovering nickel

A by recovering nickel from a by-product of the electrolytic nickel production process with chlorine leaching, it is possible to reduce the nickel remaining in the products, capable of realizing further simultaneously simplified cementation step Nickel to provide a method of recovery. A nickel recovery step S60, in the nickel recovery process S70 and nickel recovery step S80, S ° slurry is a by-product of the electrolytic nickel production process with chlorine leaching from the residue Fureka and chlorine leach residue, chlorine 80g / L~390g / L and with an aqueous solution containing copper 30 g / to 70 g / L, respectively to recover the nickel. .FIELD 1
