Separation and Recovery of Cobalt and Nickel from Sulfuric Acid Leach Liquor of Zinc Smelting Residue with Acidic Extractants

Rare metals have become indispensable for the production of parts such as batteries, motors, and semiconductors, which are important achieving high functionality in products advanced industries decarbonized society xEV (electric vehicles) AI / IoT. As spread is promoted toward a society, demand in-vehicle lithium-ion batteries expected to increase significantly. Therefore, cobalt used positive electrode material nickel, cobalt, lithium manganese, etc. In future, competition resources intensify with developed emerging countries, it will even more build supply chain secure stable supply. building chain, improve recovery rate nickel by recovering from unused improving smelting process.
