| 摘 要： | 对澳大利亚某铜尾矿进行了选矿试验研究，采用浮选—磁选联合工艺流程，综合回收尾矿中的硫、铁元素。试验结果表明:采用新型XT-01作为硫铁矿捕收剂，可获得硫品位为49.80%、回收率为92.58%的硫精矿；浮硫尾矿采用湿式弱磁选机磁选，获得了铁品位为64.11%、全铁回收率为45.91%的铁精矿，实现了铜尾矿中硫、铁的综合回收。

| Abstract: | Detailed beneficiation test research was conducted on a copper tailings from Australia, and then a combined flowsheet of flotation-magnetic separation was adopted for comprehensive recovery of sulfur and iron in tailings. The result showed that new-type XT-01 as the collector for pyrite, a sulfur concentrate with the sulfur grade of 49.80% and recovery of 92.58% can be obtained. After flotation, the magnetic separation test which used wet low intensity magnetic separator has been done on flotation tailings, an iron concentrate with the iron grade of 64.11% and the total iron recovery of 45.91% was obtained. Comprehensive recovery and utilization of sulfur and iron in copper tailings was realized. |
