Abstract
The elution behavior of inorganic matters from SS013, SS015, SS020, SS027, SS029 and SS045 was investigated. In particular, the amount of elution and time course were estimated by using ion chromatography. The time course of elution indicates that soluble minerals on the surface of coal was rapidly eluted within 5 minutes. The elution rate from SS027 was higher than those from SS020 or SS029. The amount of soluble minerals determines elution rate. We concluded that there was little relation between the amount of elution and ash content.
