Aimed at the complex and micro-fine specularite ore,comparison tests of high-intensity magnetic separation, gravity separation and flotation were performed. The results show that when the combined technological flowsheet of high-intensity magnetic separation-desliming-Anionic reverse flotation is selected,the mineral processing index is satisfactory (the yield of the iron concentrate as 40.84% ,the grade as 60.63% and the total recovery as 62.50% ). Hie technological research can provide a reference for the similar complex and refractory hematite ore.%针对某复杂微细粒镜铁矿进行了强磁、重选、浮选等多种选矿工艺方案对比试验,结果表明,采用强磁-脱泥-阴离子反浮选联合流程,可获得比较满意的选矿技术指标(铁精矿产率40.84％、品位60.63％、总回收率62.50％),对开发类似复杂难选镜铁矿具有一定的参考、借鉴作用.
