摘　　要：在攀枝花铁精矿性质研究的基础上,进行了细磨深选、粗细粒级分别分选、复合力场分选(包括新型提铁降杂磁选机磁选、磁选柱分选、磁场筛分选)等试验研究,结果表明,无论采用何种磁选工艺,均可有效提高攀枝花铁精矿品位2个百分点以上,且能保证回收率在97%以上。对不同磁选工艺的特点分析,可对攀枝花铁精矿提铁降杂实践提供参考。Based on the properties of Panzhihua iron concentrate, the technologies of fine - grinding and deep - processing, separation based on size fractions, separation based on multiple foree fields （ including JCTN RCG - DDC permanent magnetic separator, magnetic separation column and mag- netic field selden） were carried out. The reesults show that, regardless of the magnetic separation process, Panzhihua iron concentrate grade can be improved by more than 2 prorcenrage points and the recoveries were above 97%. The analysis of the characteristics of different magnetic separation technology can provide refefence for the practice of improving iron content while decreasing impurities for Panzhihua iron concentrate.
