摘　　要：本文通过对电炉高镍锍提取工艺流程及铜镍互含指标进行研究与应用,利用二期II系统单独处理电炉高镍锍、降低球磨机处理矿量以及调整浮选加药量等措施,稳定了生产流程,降低了铜镍互含指标,实现了电炉高镍锍的及时变现,为镍电解生产提供了质量合格的生产原料。According to the research and application of the extraction process of high nickel matte in electric furnace and the mutual inclusion index of copper and nickel,this article proposes a method to optimize process and index of nickel matte in electric furnace:respectively high nickel matte,reduce the ore processing amount of ball mill,and adjust flotation dosage,thus the production process can be stabilized and the mutual inclusion index of copper and nickel can also be reduced,which realizes rapid extraction of pure nickel and provides eligible material for producing electrolytic nickel.
