广东某含铁钨矿选矿试验

Mineral Processing Experiment of an Iron-containing Tungsten Ore of Guangdong

对以白钨矿和磁铁矿为主的广东某含铁钨矿,采用优先脱硫—弱磁选选铁—常温浮选白钨的原则流程进行了选矿工艺研究。结果表明,采用1粗1扫脱硫、1粗1精弱磁选选铁、1粗3扫5精浮选选钨流程处理该矿石,最终获得了铁品位为64.72%、回收率为58.72%的铁精矿,WO3品位为56.38%、回收率为86.45%的钨精矿,硫品位为25.54%、回收率为71.13%的硫精矿。

For a iron-containing tungsten ore of Guangdong with main content of scheelite and magnetite, mineral pro- cessing with the flow-sheet of preferential sulfur removal-iron concentration by low intensity magnetic separation-tungsten concentration by flotation at normal temperature is investigated. The resuhs show that iron concentrate with Fe grade of 64. 72% and the recovery of 58.72% ,Tungsten concentrate with WO3 grade of 56. 38% and recovery of 86.45% , Sulfur Concentrate with S grade of 25.54%, and recovery of 71.13% were obtained by the flow-sheet of one roughing-one scaven- ging for sulfur removal, one roughing-one cleaning for iron concentration by low intensity magnetic separation, one roughing- three scavenging-five cleaning for Tungsten concentration by flotation.
