Manufacturing Method of Highly Purified Nickel Sulfate from the raw materials of Nickel Cobalt and Manganese Mixed Sulfide Precipitation

摘要

The present invention relates to a method for manufacturing nickel sulfate used for a secondary battery cathode material, industrial electrolytic nickel plating, electroless nickel plating, and the like, and more specifically, nickel containing calcium and cobalt under a continuous process including a recycling process. And extracting more than 97% of nickel components from manganese mixed sulfide raw materials, minimizing the use of organic solvents and discharging wastewater, as well as additionally recovering cobalt, zinc, manganese components and producing high purity sodium sulfate. It relates to a method for producing as high a purity nickel sulfate as possible.
