锡铁山铅锌矿浮选尾矿再选试验研究

Experimental Study on Re-beneficiation of Pb-Zn Ore Flotation Tailings of Xitieshan

含黄铁矿15.59%,金0.29 g/t、银8.28 g/t的锡铁山铅锌矿浮选尾矿具有综合回收利用价值。尾矿再选试验研究表明,在磨矿细度为-0.074 mm占70%,经过一次粗选,可获得含硫42.73%、回收率86.56%,含金1.01 g/t、回收率85.85%,含银31.91 g/t、回收率82.59%的混合粗精矿。该研究对资源综合利用具有较大的理论和现实意义。

The pyrite grade 15.59%,gold grade 0.29 g/t and silver grade 8.28 g/t of lead-zinc flotation tailings of Xitieshan has comprehensive recycling value.Experimental study on re-beneficiation of tailings showed that the sulfur grade 42.73% and the recovery of 86.56%,gold grade 1.01 g/t and the recovery of 85.85% and silver grade 31.91 g/t and the recovery of 82.59% could be obtained with the grinding fineness of -0.074 mm accounted for 70% by only one roughing.This study has great theoretical and practical significance for the comprehensive utilization of resources.
