高镍毓缓冷技术试验研究及应用

Research and Application of Slow Cooling Technology Used in High Nickel Matte

大型冶炼企业以硫化镍矿为原料,提取其中的有价金属,火法冶炼是非常关键环节,直接影响金属回收率和经济性,高镍作为冶炼中间产品,含有价金属达到70%~75%,主要金属种类包含镍、铜、钴、贵金属等,开展缓冷技术研究对高镍内硫镍矿、辉铜矿、合金颗粒粒度长大具有非常重要作用,对于后续浮选分离经济性有着直观的影响。因此,对高镍开展缓冷技术研究,对于提高企业生产经营过程中金属回收率提升等具有非常积极的意义。

In large smelting enterprises,nickel sulfide ore is used as raw material to extract valuable metals.Fire smelting is a very key link,which directly affects metal recovery and economic type.High nickel matte,as an intermediate product,contains valuable metals up to 70%~75%,the main metal types include nickel,copper,cobalt and precious metals.The research of slow coling technology plays an important role in high nickel matte sulfide,chalcocite,and the grain size growth of alloy particles,and has a direct effect on economy of the subsequent flotation separation.Therefore,the research on slow cooling technology used in high nickel matte has a very positive significance for improving metal recovery in production and operation.
