采用立式搅拌磨机对鳞片石墨进行了磨矿研究，得出最佳条件为：采用Φ6 mm纳米陶瓷球为磨矿介质，磨机转速100 r／min，磨矿时间4 min，磨矿浓度30％。按此条件下进行4段再磨、4次浮选的闭路试验流程，可获得石墨品位为92．58％、回收率为94?71％、精矿中＋0．15 mm粒级含量为56．12％的良好指标。

Vertical agitating mill was employed to study the grinding performance of flake graphite, and therewith, mill speed, grinding time and grinding density were optimized as 100 r/min, 4 min and 30%, respectively, while Φ6 mm nanostructured ceramic ball was chosen as the grinding medium. Under the above optimal conditions, a closed?circuit flowsheet consisting of four?stage regrinding and four?stage flotation resulted in a concentrate with 92.58% graphite grade at 94.71% recovery and 56.12% in +0.15 mm fraction.
