| Abstract: | The main problems existing in the coal float-and-sink analysis are introduced in this paper,such as the difficulty of being moisten for raw coal and the abnormal phenomena that ash yield in lower density coal is higher than that in higher density coal.And the reasons are analyzed and the corresponding solutions are proposed. |
