摘　　要：以某地鳞片石墨浮选精矿为原料,研究了碱量、酸量、焙烧温度、煅烧时间等工艺参数对提纯效果的影响。结果表明:加碱焙烧碱酸法可使固定碳含量为89.69%的石墨精矿提纯至固定碳含量为95.86%的产品。In this study,graphite concentrate was purified by alkaline-acid method.The effects of the amount of alkaline and acid,calcination temperature and time on purifying effect were investigated.The result shows that the content of carbon in the alkaline-acid method can be reised from 89.69%to 95.86%by this method.
