某选锌尾矿中硫矿物的回收试验

某浮锌尾矿中硫含量为10.13%，主要硫化物为磁黄铁矿和黄铁矿。采用磁-浮联合流程进行了硫回收试验研究，通过1粗1精弱磁选和1粗1精1扫浮选可获得硫品位为35.59%、回收率为64.82%的磁选硫精矿和硫品位为31.09%、回收率为23.42%的浮选硫精矿，综合硫精矿硫品位为34.27%、回收率为88.24%。

Experimental Study of Sulfur Recovery from a Separated Zn Tailing

The sulfur content of a Zinc flotation tailings is 10.13%,the main sulfide is pyrrhotine and pyrite.The test research used magnetic separation-flotation joint flowsheet for sulfur recovery,by one rough and one cleaning floatation low intensity magnetic separation,got magnetic separation sulfur concentrate with S grade of 35.59%,recovery of 64.82% and flotation sulfur concentrate with S grade of 31.09%,recovery of 23.42%,merging the sulfur concentrate,the S grade is 34.27%,recovery is 88.24%.
