Document Type and Number:
WIPO Patent Application WO/2023/128042
Kind Code:
A1
Abstract:
The present invention relates to a hydrometallurgical method for recovering nickel sulfate. More specifically, the hydrometallurgical method for recovering nickel sulfate uses source material containing nickel (Ni), cobalt (Co), and manganese (Mn) to extract an aqueous nickel sulfate solution of high purity using a hydrometallurgical process, and the effectiveness of the process is increased by preventing impurities in the form of salt from precipitating during the solvent extraction process by using nickel hydroxide rather than sodium hydroxide or sodium carbonate as the neutralizing agent.
