摘　　要：为查明四川攀西某钒钛磁铁矿床中-深部矿石中有用矿物的赋存状态,采用化学分析、电子探针、X射线衍射、MLA和光学显微镜等手段进行了矿石主要化学成分、矿物组成、粒度和嵌布特征以及铁、钛赋存状态的研究。结果表明:矿石中铁主要赋存于钛磁铁矿中,钛主要赋存于钛铁矿中。矿石中铁的理论回收率为65%左右;钛的理论回收率为68%左右。研究结果对某钒钛磁铁矿床中-深部矿石的选冶研究具有重要指导意义,也对红格矿田乃至攀西地区基性-超基性钒钛磁铁矿矿石工艺矿物学研究具有重要启示。The main chemical constituents, mineral composition, mineral composition particle size, embedding characteristics and the occurrence of iron and titanium of the ore were studied by means of chemical analysis, electron probe, X-ray diffraction, MLA and optical microscope in order to ascertain the occurrence status of useful minerals in Middle - deep Ore body of a V-Ti magnetite deposit, Panxi area, Sichuan Province. The results show that iron is mainly present in titanium magnetite, and titanium is mainly present in ilmenite. The theoretical recovery of iron in the ore is about 65%; the theoretical recovery of titanium is about 68%. The results of this study are of great significance to the selection for the V-Ti magnetite deposit, and it is also of great significance for the treatment of this type of ore in the Hongge ore field and Panxi area.
