摘要/Abstract

摘要： 详细介绍了目前国内外石墨提纯的各种方法，主要有浮选法、碱酸法、氢氟酸法、氯化焙烧法和高温提纯法，系统地阐述了它们的基本原理、工艺条件、研究进展以及在实际生产中的应用情况，在进行了各种方法的优缺点对比之后，得出经过改进的碱酸法仍不失为工业提纯石墨的最好方法。

关键词: 石墨提纯, 浮选法, 碱酸法, 氢氟酸法, 氯化焙烧法, 高温提纯法

Abstract: A detailed description is given on various methods for graphite purification at home and abroad，mainly including flotation，alkali-acid method，hydrofluoric acid washing approach，chloridizing roasting and purification in high temperature.Based on the systematic exposition of their basic principles，progress conditions，research progresses and practical applications，the comparison of the merits and demerits of these methods have led to a conclusion，which is that the alkali-acid method could still be considered as the best way in graphite purification after being improved.

Key words: Graphite Purification, Flotation, Alkali-acid method, Hydrofluoric acid washing approach, Chloridizing roasting, Purification in high temperature
