摘　　要：对内蒙古地区某低品位石墨矿石进行选矿试验研究,在确定最佳粗选条件的基础上,采用5次再磨6次精选进行开路试验、闭路试验,最终使石墨固定碳含量由3.51%提高到90.47%,回收率达70.56%。A beneficiation test of a refractory graphite ore from Inner Mongolia area was studied. On the basic of the best primary grinding fineness, an open and closed trial was conducted by five-times-regrinding and six-times-cleaning. Finally, the graphite concentrate of fixed carbon grading increased from 3.51% to 90.47% and the recovery of graphite was 70.65%.
