摘　　要：为了提高广西某高品位铅锑锌多金属硫化矿铅锑浮选指标,通过浮选试验研究开发出了新型抑制剂TF和组合捕收剂FG+HB,铅锑浮选闭路试验获得了铅锑精矿中铅品位为26.34%,锑品位为25.86%,铅回收率为94.03%,锑回收率为93.34%的良好指标,较现生产工艺指标铅、锑回收率分别提高了7.56个百分点和7.39个百分点。To increase lead-antimony flotation indexes of a high grade lead-antimony-zinc polymetal- lic sulphide ore in Guangxi, new depressant TF and combined collectors FG ＋ HB were developed through flotation experimental study, good indexes of lead grade 26.34% and recovery rate 94.03% , antimony grade 25.86% and recovery rate 93.34% in lead-antimony concentrate were obtained in lead-antimony flotation closed circuit test, recovery rate of lead and antimony has increased 7.56% and 7.39% com- pared with current production index.
