铁精矿选矿指标

  将选铁的一段磁尾和二段磁尾合并作为选钛物料,分别进行了强磁-重选流程、强磁-浮选流程的试验,在重选和浮选前均采用强磁选别工艺,抛弃了大量的尾矿,使后续作业的物料大幅度地减少。强磁选的选别指标为(对选钛物料):强磁精矿产率为42.03%,TFe品位为22.44%,含TiO2—27.53%,回收率TFe60.78%、TiO2为83.07%。对强磁精矿采用跳汰机精选,获得产品指标:

  通过对比可见,强磁精矿通过跳汰机选别,能够获得TiO2—48%以上的钛精矿,但作业回收率仅能达到65%±,若用于生产,其回收率将会更低;而浮选获得的钛精矿不仅品位较高,且作业回收率达到89%±,高出跳汰机选别时24%。所以,针对百草钒钛磁铁矿的性质,钛铁矿采用强磁选-粗粒再磨-浮选工艺流程是非常有效的选矿方法
