摘　　要：为了综合回收攀枝花低品位钒钛磁铁矿石,对其进行了详细的试验研究。结果表明,采用干式抛尾与阶段磨矿、阶段选别的选矿工艺流程,可获得产率13.65%、TFe品位54.14%、回收率40.56%的合格铁精矿,选铁尾矿采用粗细分选工艺流程可获得产率10.80%、Ti O2品位47.08%、回收率63%的合格钛精矿。For comprehensive recovery and utilization of low grade vanadium titanium magnetite ore, detailed experimental research were carried out. When using the beneficiation process com-bined with dry discarding of tailings, stage grinding and stage separation, the qualified iron concen-trate with a yield of 13. 65% ,TFe grade of 54. 14% and recovery rate of 40. 56% can be got. The process of coarse and fine separation was used in magnetic separation of rougher tailings, and the eligible titanium concentrate with a yield of 10. 80%, TiO2 grade of 47. 08% and recovery rate of 63% can be obtained.
