摘要: 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。

Abstract: 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.

Key words: Scheelite, Magnetite, Sulfur removal, Normal temperature flotation
