摘　　要：通过对该复杂混合型铜矿的试验研究,确定处理该矿石的合理工艺流程.研究表明,以CaO作为黄铁矿抑制剂,Na2S为氧化铜矿活化剂,戊黄药为捕收剂,730A为起泡剂,采用一粗二精一扫的混合浮选流程,可获得产率为4.94%的Cu精矿,精矿含Cu 13.28%,含Pb 5.87%,含Ag 407 g/t;回收率Cu为82.51%,Pb为55.77%,Ag为79.98%,为该矿的开发利用提供了技术依据.Through the test study on the complex mixed copper mine,the reasonable technological process was determined.The results showed that CaO was used as pyrite inhibitor,Na2S as oxidizing copper ore activator,amyl xanthate as collector,and 730A as foaming agent,by adopting the mixed flotation process of one roughing,two cleaning and one scavenging,he Cu concentrate with a yield of 4.94%,Cu 13.28%,Pb 5.87% and Ag 407 g/t could be obtained.The recovery rates of Cu,Pb and Ag were 82.51%,55.77% and 79.98% respectively,which provided a technical basis for the development and utilization of the mine.
