The Mineral Matter Characteristics of Some Chinese Coals

LiuXinbing(Department of Coal Preparation and Utilization,CUMT)  
The mineral matter has been separated from 18 coal samples with a low temperature asher,and analyzed by means of X-ray diffraction method.Based on the results of chemical analysis of the coal ash, with reference to the standard composition of minerals the content of various mineral phases in the coal ash has been determined.Furthermore,this paper summarizes the mineral matter characteristics of the coal samples and discusses the relationship between the composition of mineral matter in coal and its depositional environment
