某金锑钨尾矿中金和钨的浮选回收试验

Experimental Study on Comprehensive Recovery of Gold and Tungsten from a Certain Tailing of Gold,Antimony and Tungsten

针对某矿业公司金锑钨选厂重选—浮选联合流程产生的尾矿进行了再选回收金、钨矿物的试验研究。试验根据生产尾矿性质,采用金、钨依次优先浮选工艺流程,通过闭路试验,获得了含金14.10 g/t,金回收率为的50.36%金精矿和含钨1.22%,钨回收率为49.61%的钨粗精矿。金精矿可直接作为产品,钨粗精矿可返回现场流程作进一步的处理。试验结果为现场综合利用尾矿资源提供了依据。

The experimental study on gold and tungsten recovery from the a certain tailing of gold,antimony and tungsten which was treated by the combined flow-sheet of gravity separation and flotation is carried out.According to the tailing s characteristic,the selective flotation flow-sheet with the closed circuit is adopted.Then,the gold concentrate of 14.10 g/t with gold recovery of 50.36% and Tungsten coarse concentrate of 1.22% with Tungsten recovery of 49.61% are obtained respectively.The gold concentrate can be used as products directly and Tungsten coarse concentrate should be sent to the on-site process for retreatment. This result can provide a foundation for comprehensive on-site utilization of tailings resources.
