从河北某铁尾矿中回收二氧化钛的工艺研究

Experimental study on recovery of kronos from iron-separation tailings

摘要: 针对河北某磁铁矿尾矿中有用矿物TiO₂品位为7.18%,造成钛资源浪费的情况,采用强磁选-摇床选别的联合流程,最终可以获得产率为23.07%、品位为27.31%、回收率为87.75%的较高品位钛精矿,以及产率为76.93%、品位为1.14%、回收率为12.25%的合格尾矿。

Abstract: It is determined through analysing the feature of tailings of Hebei iron stone,which contains TiO₂ 7.18%,adopting"high intensity magnetic separation-shaking table concentration.The results show that the concentrate with a TiO₂ grade of 27.31%,recovery 87.75% and productivity 23.07% and the tailing with a TiO₂ grade of 1.14%,recovery12.25% and productivity 76.93%.
