Experimental study on optimization of flotation reagents for ilmenite froman iron dressing tailing in Panxi area

  • 摘要: 针对攀西某选铁尾矿进行了钛铁矿浮选药剂优化试验研究,其TiO2品位为16.6%,主要矿物为钛铁矿、钛磁铁矿、辉石、橄榄石,次要矿物为斜长石、绿泥石。经过捕收剂、抑制剂、硫酸等药剂优化试验,利用硫酸+EMA+MOH,通过磁选除铁-浮选脱硫+一粗一扫五次精选选钛流程,闭路试验可以获得钛精矿产率25.18%,TiO2品位46.48%,回收率71.31%的良好指标,为攀西矿区选铁尾矿中钛铁矿的回收提供技术参考。
