摘　　要：河南某铁矿主要含磁铁矿和镜铁矿,针对该铁矿磁铁矿嵌布粒度较粗、镜铁矿嵌布粒度较细的矿石性质,采用永磁筒式磁选机回收磁铁矿,SSS-I高梯度磁选机回收镜铁矿.在原矿铁品位为27%时,采用阶段磨矿阶段磁选工艺,获得铁精矿品位64.22%、回收率75.0%的指标.An iron mineral in Henan province,China mainly contains magnetite and specularite. Due to the disseminated grain size of magnetite is relative coarse and specularite is fine,recovering magnetite by the separation of permanent drum magnetic separator and recovering specularite by SSS-I high gradient mag- netic separator were used. When the ore is with grade of Fe being 27%, the grade of iron concentrate 64.22% with recovery of 75.0% is obtained by the stage grinding and stage magnetic separation technology.
