Abstract

This invention describes a method for producing nickel sulfate solution consisting of a leaching step where nickel cathode is soaked in sulfuric acid under high temperature and high pressure to produce the leaching solution, a neutralization step which neutralizes the leaching solution produced in the leaching step to produce the neutralized solution, and a filtration step which filters the neutralized solution produced in the neutralization step to produce the filtrate.
