摘　　要：云南迪庆有色金属有限责任公司普朗铜矿属多金属超大斑岩型铜矿,工艺矿物学分析结果表明,普朗铜矿浮选尾矿矿样中铜矿物主要富集在+0.074 mm粒级以及-0.025 mm粒级,其中+0.074 mm粒级主要为含铜连生体。采用大型高效浮选机技术对普朗铜矿浮选尾矿再选进行试验研究,结果表明,HIF-680浮选机的浮选精矿经再磨后返回到主流程粗选作业的指标较好,粗选回收率提高了1.25个百分点,且再磨的最佳磨矿细度为-0.074 mm占比77.64%。依托于大型高效浮选机技术的尾矿再选工程,提高了资源利用率,为选厂创造可观的经济效益。Pulang Copper Mine of Yunnan Diqing Nonferrous Metals Co.,Ltd.is the multi-metal super large porphyry copper mine.The results of process mineralogy analysis show that the copper minerals mainly lost in the+0.074 mm and-0.025 mm fractions,and the+0.074 mm fraction is mainly cop-per-containing intergrowth.The large-scale high-efficiency flotation machine technology was used to study the re-concentration of flotation tailings in Pulang copper mine.The results show that the best results was achieved by returning the concentrate of HIF-680 flotation machine to rougher in main flow after regrind-ing.The rougher recovery increased by 1.25 percentage points,and the optimum grinding fineness of re-grinding was-0.074 mm accounting for 77.64%.The tailings reconcentration project based on large-scale high-efficiency flotation machine technology improves the utilization rate of resources and creates considerable economic benefits for the plant.
