| Abstract Scope |
Nickel is widely used in stainless steel and alloys for its corrosion resistance and thermal conductivity. Additionally, as demand for high nickel increases to expand battery capacity, the importance of nickel is steadily increasing. Consequently, research on securing nickel raw materials by utilizing the recovery of nickel from primary and secondary resources. This study aimed to recover nickel efficiently via intermediates and nickel sludge. To maximize the leaching efficiency under atmospheric pressure, the physical and chemical properties of the material were controlled through a calcination process and an electrochemical pulverization process. Furthermore, the removal rates of impurities in the pregnant leach solution (PLS) were confirmed through precipitation and solvent extraction processes. This research contributes to the sustainable supply of nickel by enabling efficient and environmentally friendly nickel separation compared to existing processes and developing various metal recovery technologies. |
