摘　　要：　　简述了隐晶质石墨高纯化基本原理。根据矿样原料性质,采用改进的火法—湿法提纯工艺对某地隐晶质石墨进行了试验研究,并确定了最佳工艺参数。研究结果表明,改进的火法—湿法提纯法可将固定碳含量为 84. 18%的隐晶质石墨提纯至固定碳含量达 99. 25%的产品。The basic principles of highly purification for the aphanitic graphite are briefly discussed in this article. According to the characteristics of raw materials,an improved combined pyro-hydro technology is selected for purification of the aphanitic graphite,and the optimal technological parameters are determined. Research results show that the improved pyro-hydro purifying method can increase fixed carbon content of the aphanitic graphite from 84.18% to 99.25%.
