Abstract: Taking a foreign carbon bearing copper sulfide ore as the research object, the technological mineralogy of the ore sample is studied, and the mineral processing research is carried out by using efficient copper collector AP.The study investigates the effects of process factors such as grinding fineness, types of reagents, dosage of reagents, and pH on the mineral processing index.The results show that for the raw ore containing 1.21% copper and 1.29% S, first stage grinding fineness reaches -0.074 mm 65%.The copper flotation process adopts the process of “one-stage roughing, one-stage scavenging, and three-stage cleaning”.Qualified copper concentrate is obtained through closed-circuit test, with a copper content of 25.20% and a recovery rate of 92.26%.The results indicate that the collector AP has strong collection ability and good selectivity for the studied ore samples.
