摘　　要：对陕西大西沟某铁品位15.70%的选铁尾矿开展了有价组分综合回收试验研究,采用浮选铜硫、强磁选提铁、焙烧选铁、摇床重选-浮选提取重晶石和云母工艺,获得了TFe品位60.17%(S含量0.11%)、TFe回收率66.74%的铁精矿,S品位47.86%、回收率66.58%的硫精矿,Cu品位19.79%、回收率31.24%的铜精矿,BaSO_(4)品位86.96%、回收率9.15%的重晶石粗精矿和K_(2)O品位6.66%、回收率6.63%的云母精矿,实现了尾矿分质综合利用。Experimental studies on comprehensive recovery of valuable resources in iron-dressing tailings with TFe grade of 15.70%were conducted by adopting processes consisting of Cu-S bulk flotation,high intensity magnetic separation to reclaim Fe minerals,roasting reduction of Fe minerals,and shaking table gravity separation and flotation separation to recover barite and mica.As a result,the experiment produced an iron concentrate with TFe grade of 60.17%,S content of 0.11%and iron recovery of 66.74%,a sulfur concentrate grading of 47.86%S at 66.58%recovery,a copper concentrate grading 19.79%Cu at 31.24%recovery,a barite rough concentrate with BaSO_(4)content of 86.96%and recovery of 9.15%,and a mica concentrate with K_(2)O content of 6.66%and recovery of 6.63%,respectively.In this way,comprehensive utilization of tailings can thus be realized.
