摘　　要：研究了某尾矿的工艺矿物学性质及回收铁精矿、硫精矿的工艺流程。通过采用螺旋溜槽预富集-磨矿-弱磁选-强磁选-浮选硫-反浮选硅工艺回收铁精矿、硫精矿,获得的铁精矿TFe62.58%、回收率32.63%,硫精矿S品位37.57%。The properties of process mineralogy of the tailings and recovery technological process of iron concentrate and sulfur concentrate were studied. An iron concentrate grading of 62.58% Fe and recovery of 32.63% and sulfur concentrate grading of 37.57% S can be obtained by intensity magnetic separation- high intensity magnetic the process of preconcentration by sprial chute, grinding- low separation -sulfur flotation -silicon reverse flotation.
