摘　　要：刚果(金)某矿山的硫化铜精矿中,铜矿物主要以辉铜矿形式存在。冶金试验证明,该硫化铜精矿采用火法冶炼工艺,只需要一道吹炼工序,即可直接完成铜、渣分离,产出粗铜产品,工艺流程短,铜直收率为93.05%,炉渣中的铜可以通过渣选工艺回收,熔剂率为19%,燃料率为11%;硫化铜精矿焙烧后转化成氧化矿,再进行湿法冶炼,铜浸出率为99.37%,浸出液不需要萃取提纯,直接电积生产高纯阴极铜产品;硫化铜精矿采用氧压浸出方案,直接通过湿法冶炼生产阴极铜产品,铜浸出率为98.53%。In the sulfide copper concentrate of a mine in the Congo(Kinshasa),copper minerals mainly exist in the form of chalcocite.Metallurgical experiments have shown that the copper sulfide concentrate can be directly separated from slag using pyrometallurgical process,with only one blowing process,producing crude copper products,and the process flow is short,with a copper yield of 93.05%,copper in the slag can be recovered through slag selection process,with a flux rate of 19%and a fuel rate of 11%;copper sulfide concentrate is converted into oxidized ore after roasting,and then subjected to hydrometallurgy,and the copper leaching rate is 99.37%,and the leaching solution does not require extraction and purification,high purity cathode copper products are directly produced by electrodeposition;copper sulfide concentrate adopts an oxygen pressure leaching scheme to directly produce cathode copper products through wet smelting,with a copper leaching rate of 98.53%.
