| 摘 要： | 为提高某锌、铁多金属硫化矿的选别指标,对该矿进行了选矿试验研究,探索出了"部分浮硫—锌硫混浮—粗精矿再磨选锌—混浮尾矿选铁"的选矿工艺流程,使锌精矿品位和回收率分别提高了8%、19%左右,铁精矿中硫含量由0.6%以上降到了0.23%,铁回收率提高了15%左右。

| Abstract: | In order to increase separation index of a Zn-Fe polymetallic sulphide ore,an experimental research on mineral processing technology was conducted.The technological flowsheet of "partially sulphur flotation-bulk flotation of zinc and sulphur-regrinding of rough concentrate and zinc flotation-iron flotation from the tailings of bulk flotation" was developed.The grade of concentrate and recovery is increased about 8% and 19% respectively.The sulphur content in the iron concentrate decreased from more than 0.6% to 0.23%,and the recovery of iron is increased by 15%. |

| Keywords: | Polymetallic sulphide ore Partially sulphur flotation Sulphur-removal of iron concentrate Regrinding of rough concentrate |
