高品位硫化铜精矿冶炼工艺方案探讨

Discussion on Smelting Process of High Grade Copper Sulphide Concentrate

以辉铜矿为主的高品位硫化铜精矿铜金属品位高,硫和铁含量低,该类精矿采用湿法冶炼可以直接产出质量较高的阴极铜,但需要增加焙烧工序,工艺流程长,硫回收难度大;采用火法冶炼生产粗铜,工艺流程短,投资和运行成本低,但需要购买硫铁矿或黄铜矿配料。

High grade copper sulfide concentrate with high copper metal grade and low iron content, can be produced by wet process,and the cathode copper with high quality can be produced directly, but it needs to increase the roasting process, the process is long, sulfur recovery is difficult. The production of crude copper smelting by pyrometallurgical process, with short process, low investment and operating costs, but it needs to buy chalcopyrite pyrite or ingredients.
