and power. About 50% of the current worldwide production of nickel is derived from sulfide ores while the balance of new nickel is derived from lateritic sources [1, 2]. Primary new nickel production... of the electrolyte, lower cathodic nickel and anodic chloride overpotential, higher solubility and higher activity coefficient [10]. Main production facilities of nickel from sulfide-chloride electrolyte use......

solution 1 Introduction Nickel is an important nonferrous metal which is widely used in stainless steel, electroplating, etc [1-2]. Nowadays, nickel is mostly produced form sulfide ores. Because of the immoderately exploitation, the high grade ore, especially sulfide ore is exhausted gradually. The sulfide ore’s insufficient makes the utilization of nickel oxide ore urgent, especially the low grade oxide......
