摘　　要：通过对山东省沂南铜井金矿尾矿工艺矿物学研究,尾矿中可利用的矿物为磁铁矿、石榴子石。根据矿物性质不同,采用弱磁选铁,强磁选石榴子石,重选提纯的选矿工艺,最终获得铁精矿和石榴子石精矿。为提高尾矿资源综合利用率提供理论依据,对促进矿山的可持续发展有重要意义。Through mineralogical research on the copper well tailings of Yi'nan gold deposit in Shandong province,it was found that the minerals available in the tailings are magnetite and garnet.According to different mineral properties,a beneficiation process of weak magnetic separation of iron,strong magnetic separation of garnet,and gravity separation and purification is adopted to ultimately obtain iron concentrate and garnet concentrate.It will provide theoretical basis for improving the comprehensive utilization rate of tailings resources.It is of great significance for promoting the sustainable development of mines.
