See full text

A nickel recovery process capable of decreasing nickel remaining in a byproduct by recovering nickel from the byproduct of electrolytic nickel manufacturing process by chlorine-leaching, and also, capable of simplifying a cementation step simultaneously, is provided. In a nickel recovery step S60, a nickel recovery step S70 and a nickel recovery step S80, nickel is recovered in each step from S0 slurry, residue flaker and chlorine-leached residue, which are byproducts of electrolytic nickel manufacturing process by chlorine-leaching, by using an aqueous solution containing 80 g/L to 390 g/L of chlorine and 30 g/L to 70 g/L of copper.
