摘　　要：针对双龙镍蛇纹石矿进行Ni浮选综合回收试验研究,蛇纹石矿磨矿易泥化,影响Ni浮选指标,通过试验对比表明浮选前需脱泥。探讨摇床脱泥工艺条件,确定了摇床粗选-粗选中矿再选-摇床混合精矿浮选工艺流程。然后通过磨矿细度、浮选药剂制度调整,最终获得了精矿Ni品位8.20%,Ni回收率14.09%的综合利用优良指标。Research on the comprehensive recovery of Ni of Shuang Long nickle serpentine ore was carried on. But serpentine ores produce a large number of fine mud after grinding so that flotation indexes of Ni are seriously affected. Desliming is necessary before flotation through comparison test. By Discussing table desliming conditions,the process of table roughing-reelection of middlings-mixed concentrate flotation process is determined. By adjusting grinding fineness and flotation reagent system,good index is obtained andthe concentrate grade of Ni is 8. 20% and the recovery rate of Ni is 14. 09%.
