When the flow rate and/or the temperature of the post-neutralization solution circulated reaches a predetermined value, a sulfurization treatment is applied to the post-neutralization solution in the dezincification reaction tank to form zinc-sulfide-containing mother liquor for nickel recovery and adjust the switching valve.
