摘　　要：针对某铁矿山尾矿开展了矿石性质研究,并探索采用磁选方法从该尾矿中回收含铁矿物的可行性。物相分析结果表明,该尾矿中磁铁矿含量约为40%,且磁铁矿解离度约97%。在铁尾矿中铁品位为19.87%的情况下,无需磨矿,经过一次粗选即可获得铁品位68.96%、回收率39.40%的选别指标。Based on the study on ore properties ol tailings from an iron m ine,the feasibility ol recovering ferrous minerals therein by magnetic separation method was discussed.The mineral composition and mineralogical analysis indicated that,magnetite,with a liberation rate of 97%,accounted for about 4 0%of ferrous minerals in the tailings.It is found that iron tailings with Fe grade at 19.87%going through one roughing process without grinding can result in 39.40%Fe recovery to a concentrate grading 68.96%Fe.
