对云南某低品位钛铁矿进行了选矿试验研究，采用弱磁与强磁相结合的方案进行抛尾，可抛掉TiO2品位为1．18％、产率为81．11％的尾矿，获得TiO2品位为12．38％、TiO2回收率为64．50％的抛尾精矿；抛尾精矿采用高梯度磁选预选获得 TiO2品位为22．29％、对原矿回收率为57．16％的强磁选精矿；以MOH为钛铁矿捕收剂，采用一粗三扫三精浮选流程对高梯度磁选精矿进行浮选，最终可获得TiO2品位为45．46％、TiO2总回收率为49．31％的钛铁矿精矿。

In the experimental study on beneficiation of a low?grade ilmenite from Yunnan, a combined process consisting of low intensity magnetic separation ( LIMS) and high intensity magnetic separation ( HIMS) was introduced for tailings discarding. A concentrate approaching 12. 38% TiO2 grade at 64. 50% recovery can be recovered after discarding tailings grading 1.18% TiO2 with yield of 81.11%. Then, such concentrate was subjected to HGMS, yielding a concentrate at 22. 29% TiO2 grade at 57. 16% recovery. Using MOH as ilmenite collector, a flotation flowsheet consisting of one stage of roughing, three stages of cleaning and three stages of scavenging was introduced to beneficiate the HGMS concentrate, leading to an ilmenite concentrate approaching 45.46% TiO2 grade at a total 49.31% recovery.
