摘　　要：对四川广元地区含隐晶质难选石墨矿进行选矿试验研究,在确定最佳粗选条件和粗精矿再磨细度的基础上,采用5次再磨6次精选进行开路、闭路试验,最终使石墨固定碳含量从28.29%提高到83.80%,回收率达90.17%。A beneficiation test of refractory graphite with aphanocrystalline from Guangyuan area in Sichun was studied.On the basis of the best roughing conditions and primary concentrate regrinding,an open and closed trial was conducted by five-times-grinding and six-times-cleaning,and eventually fixed carbon content of the graphite increased from 28.74% to 83.80% and the recovery rate of graphite was 90.17%.
