针对某铁矿选厂尾矿中镜铁矿粗细嵌布不均的特点，采用重选?磁选?浮选和重选?磁选?重选工艺流程分别进行选别，分别获得了铁精矿产率22．26％、铁品位65．86％、铁回收率71．76％与铁精矿产率20．44％、铁品位66．13％、铁回收率66．16％的良好试验指标。研究成果不仅为该尾矿资源的开发利用提供了技术支撑，而且对同类二次资源的高效开发具有重要的指导和借鉴意义。

According to the characteristics of uneven size distribution of specularite particles in the tailings from some iron ore concentrator, experimental studies were performed by two flowsheets respectively. Results showed that a combined process of gravity separation?magnetic separation?flotation produced an iron concentrate approaching 65. 86%Fe grade at 71. 76% recovery with a yield of 22. 26%, and another process of gravity separation?magnetic separation?gravity separation led to an iron concentrate approaching 66.13% Fe grade at 66.16% recovery with a yield of 20.44%. This study can provide a technical reference and guidance not only for the exploitation of such kind of tailings, but also for the efficient utilization of secondary resources of this kind.
