摘　　要：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。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%）.The technological research can provide a reference for the similar complex and refractory hematite ore.
