摘　　要：针对山西某区域铁精矿,分别采用单一弱磁选、阳离子反浮选和阴离子反浮选进行对比试验,最终确定采用单一弱磁选方法(磨矿+一粗一精)即可获得优质产品。在磨矿细度为-0.074 mm 90%的条件下,成功获得了产率95.03%、铁品位71.88%、回收率98.89%的超纯铁精矿。该流程工艺简单,操作方便,为该区域铁精矿进一步深加工提供了参考依据。For a certain iron ore concentrate in a certain area of Shanxi, a single weak magnetic separation, cationic reverse flotation and anion reverse flotation were used for comparative tests.. It is finally confirmed that a single weak magnetic separation method （ grinding＋one coarse one fine） can obtain high quality products.Under the condition of grinding fineness of 90 % -0.074 mm, ultra-pure iron concentrate with a yield of 95.03%, an iron grade of 71.88% and a recovery of 98.89% was successfully achieved. The process is simple in process and convenient in operation, and provides a reference for further deep processing of iron ore concentrate in the region.
