摘　　要：为提高煤系高岭岩的回收率,采用浮沉实验、ICP-AES和XRD衍射光谱分析等方法研究了煤系高岭岩在不同密度级煤矸石中的分布规律。在此基础上用锥段为复锥的重介旋流重选柱对其进行了分选,探索了低悬浮液密度下从煤矸石中回收煤系高岭岩的重介分选条件。In order to enhance the recovery of coal-bearing kaolinite, methods such as float-and-sink analysis, ICP-AES analysis and X-ray diffraction spectrum analysis were employed to investigate the distribution of coal-bearing hard kaolin indifferent-density coal gangue. On the basis of chemical analysis and mineral analysis, dense medium separation of coal gangue was performed in a cyclone with complex cone, through the separation in different suspension density, the suitable condition of coalbearing kaolinite enrichment was explored.
