  重晶石密度为4.3~4.7g/cm³,石英密度为2.5~3.0g/cm³,二者的密度差异较大,从而进行重选试验,目的是通过跳汰重选回收重晶石矿,减少重晶石对浮选的危害,改变浮选的操作性,提高浮选指标。因此,考察采用重选—浮选联合的浮选工艺流程。

  根据该矿石的磨矿细度曲线,确定磨矿细度为-200目、55%,磨矿浓度60%,磨矿后矿浆用跳汰机进行试验,查看含重晶石矿石的产率和品位。跳汰机中矿为含重晶石矿,通过跳汰选出的含重晶石矿中金品位只有0.5g/t,接近浮选尾矿品位;硫酸钡的含量达到85.6%,回收也接近60%。通过重选可 以很好的分离重晶石,可以起到降低浮选压力,提高浮选效率的作用,并且可以回收重晶石。
