广东某含铁钨矿选矿试验

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。

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

For a iron-containing tungsten ore of Guangdong with main content of scheelite and magnetite，mineral processing 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 results 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 scavenging 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.
