摘　　要：研究了青海省某微细粒磁铁矿的矿石特点,试验研究的结果表明,采用阶段磨矿-阶段弱磁选-阴离子反浮选的选矿工艺流程,可使铁精矿品位达到62.82%、回收率为59.84%,为开发利用该地区的铁矿资源提供了依据,具有较好的经济效益和社会效益。Based on the study of the properties of a micro-grained dissemination magnetite ore in Qinghai province and the analysis and comparison of experiments, the experimental research of the beneficiation flowsheet was made, namely the flowsheet consisting of staged grinding and low intensity magnetic separation and anionic reverse flotation, which obtained concentrates having 62. 82%grade and 59.84% recovery. And provided the basis of development and use of the iron ore resources in this region which have a better economic and social benefits.
