摘　　要：本文以青海某低品位铁矿为研究对象,对其进行了详细的工艺矿物学研究,并根据原矿性质特点进行选矿试验研究。在原矿全铁含量为33.35%,磨矿细度-0.076mm 63.7%,磁场强度为0.18 T条件下,采用一步磁选即可获得全铁含量为69.60%,回收率为88.63%的铁精矿。A low grade iron ore from Qinghai province was taken for beneficiation study in this paper. Detailed process mineralogy research and mineral processing experiments have been carried out. Under the condition of 33.35% total iron content,-0. 076 mm 63.7% grinding fineness and 1800GS magnetic field strength,iron concentrate with total iron content of 69.60% and iron recovery of 88.63% can be obtained using one-step magnetic sepa- ration.
