摘要
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 separationgravity 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.
