摘　　要：文章在对现再磨老系统精矿分析的基础上,通过试验室及工业分流试验研究,确定对外购铁精矿采用"磨矿—弱磁选—电磁螺旋柱—细筛—细磨—弱磁选"工艺流程可实现再磨铁精矿品位达到69%的目标。The paper analyses the concentrate from the old regrinding system,introduces the results of test in lab and industrial trail,then points out that the grade of the purchased concentrate can reach 69%after being treated by grinding-weak magnetic separation-electromagnetic spiral column-fine screening-fine grinding-weak magnetic separation.

关 键 词：电磁螺旋柱 细筛 再磨再选
