| Abstract: | This paper introduces the principles and methods of preparing of high purity graphite, which contains the flotation process, the acid-base method, the hydrofluoric acid method, the chlorination roasting method, and the high - temperature method; Besides, the advantages and disadvantages of these methods were compared and the research developments on preparation of high purity graphite were summarized in the recent years. In order to produce a comprehensive performance excellent, costeffective high- purity graphite products, much more attention should be focused on raw material nature, process characteristic, equipment investment, production energy consumption as well as environmental governance. |
