Abstract

Provided is a method with which it is possible, when causing a sulfuration reaction to occur from a sulfuric acid acidic solution containing at least nickel through use of a sulfuration agent and generating a nickel sulfide, to suitably control the grain size of the generated sulfide while maintaining high reaction efficiency. The sulfuration treatment method according to the present invention comprises supplying a sulfuric acid acidic solution that contains nickel to a reactor, adding hydrogen sulfide gas to the sulfuric acid acidic solution, and generating nickel sulfide, wherein unreacted gas among the hydrogen sulfide gas added to the sulfuric acid acidic solution is recovered, sodium hydroxide is added to the recovered hydrogen sulfide gas, sodium hydrosulfide is generated, and the resulting solution of sodium hydrosulfide is added to sulfuric acid acidic solution. At this time, when the sodium hydrosulfide solution is added, the grain size of the generated nickel sulfide is set to 50 æm or higher by 50 pcnt particle size (D50) by controlling the amount of sodium hydrosulfide solution added to the reactor to which the sulfuric acid acidic solution is supplied.
