摘　　要：江西尖峰坡锡石多金属硫化矿具有锡石结晶粒度细及硫化矿可浮性差异小等特点,采用“优先脱硫浮锌—浮选尾矿重选选锡”的工艺流程进行选别,在原矿品位Zn 0.87%,Sn 0.70%的情况下,获得了锌品位44.56%、回收率69.10%的锌精矿,锡品位54.38%、回收率53.03%的高品位锡精矿及锡品位6.54%、回收率1.25%的低品位锡精矿,锡总回收率为54.28%,锌和锡均得到有效回收.According to the study of processing mineralogy, the processes of selective flotation for sulfide, then gravity concentration for cassiterite from the flotation tailings are put forward. Under the condition of Sn and Zn are 0. 87% and 0. 70% respectively in crude ores, the Zn concentration is got which the content of Zn is 44.56%, the recovery of Zn is 69.10%; the high quality Sn concentration is got which the content of Sn is 54.38%, the recovery of Sn is 53.03%, the low quality Sn concentration is got which the content of Sn is 6.54%, the recovery of Sn is 1.25 %. Zn and Sn are recovered effectively.
