某金锑钨尾矿中金和钨的浮选回收试验

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。

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

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.
