摘　　要：对目前国内外石墨提纯的常用方法进行了评述。采用高温熔融法对隐晶质(土状)石墨进行了研究并确定了最佳工艺条件。结果表明,高温熔融法可使固定碳85.60%的隐晶质石墨提纯至97.86%左右。The authors reviewed purification methods of graphite used in China and abroad. In this study, aphanitic graphite ore was purified in a melting process at high temperature and the optimum conditions were ascertained. The results show that the content of C in the aphanitic graphite can be raised to 97.86% by the method.
