摘　　要：在磁性矿物资源的开发利用过程中,弱磁性矿物一直占据着巨大比重。因弱磁性矿物相对难选,对分选技术要求较高,与弱磁性矿物磁选相关的设备、工艺和理论的研究也在持续不断的更新。本文凝炼了弱磁性矿物磁选过程中采用的设备、工艺和理论的研究现状,并展望了未来弱磁性矿物磁选的发展方向,以期对弱磁性矿物高效率分选提供基础指导。In the development and utilization of magnetic mineral resources,weak magnetic mineral always occupies a large proportion.Because weakly magnetic minerals are relatively difficult to be selected and have high requirements for separation technology,the research on equipment,technology and theory related to magnetic separation of weakly magnetic minerals is constantly updated.In this paper,the equipment,technology and theory used in magnetic separation of weak magnetic minerals are condensed,and the development direction of magnetic separation of weak magnetic minerals in the future is prospected,so as to provide basic guidance for efficient separation of weak magnetic minerals.
