| 摘 要： | 对五种不同煤阶的煤样在25℃的条件下以苯和四氯化碳的混合液为重液进行重介离心浮沉分选,每个煤样从1.320g/cm3到1.459g/cm3分为五个密度级。根据浮沉试验结果绘制了可选性曲线,分析得出了煤的可选难易程度与煤阶无关,而与煤本身的性质有关。

| Abstract: | coals with different ranks were separated respectively into five density grades ranging from 1.320g/cm3 to 1.459g/cm3 in heavy media (C6H6-CCl4) at 25°C using centrifugal float-sink separation technique. The separation efficiency of each coal differed significantly. The washability curves were drawn according to the result of float-sink test. The conclusion is that the washability has no relation with coal rank,but depends on the coal properties. |

| Keywords: | coal float-sink separation washability curve quantitative efficiency |
