Mineral matter in coal can reflect the geochemical characteristics of coal and has a great influence on coal processing and utilization. Some of the trace elements in coal may result in pollution to the environment, or the mineral matter in coal may indeed be a mineral resource. Therefore, the study of mineral matter in coal is very important. 2.
