摘　　要：为实现云南普洱含金低品位锑矿资源的高效回收,研究了该矿的矿石性质和金、锑综合回收工艺。原矿中金、锑品位分别为2.48 g/t、0.24%,其中锑主要以辉锑矿的形式存在,金主要嵌布于硫化矿物中。通过一粗二扫二精一分离的浮选工艺流程,可获得锑金精矿和金精矿两个产品,合计金总回收率75.20%、锑总回收率85.18%,实现了含金低品位锑矿的综合回收。To realize efficient recovery of gold-bearing low-grade antimony ore resources in Pu'er city,Yunnan province,the raw ore properties and the comprehensive recovery process of gold and antimony were investigated.The raw ore contains gold at 2.48 g/t and antimony at 0.24%.The antimony mainly occurs as stibnite,and gold mainly embedded in sulfides.Two products of antimony-gold concentrate and gold concentrate were obtained through the process of one roughing,two scavenging,two cleaning and one separation.The total recovery rates of gold and antimony are 75.20%and 85.18%,respectively.The comprehensive recovery of gold and antimony was realized.
