Mineralogy and geochemistry of the Palaeogene low-rank coal from the Baise Coalfield, Guangxi Province, China

Some previous studies have investigated the enrichment origin of Sb and Cs in coal, but strong supportive evidence for the sources of the two elements in coal is still absent. The main aims of this study were to provide a better understanding of the geochemical and mineralogical characteristics of the Palaeogene No. 5 Coal from the Zhoujing coal mine, Baise Coalfield, Guangxi Province, southwestern China. The No. 5 Coal has a low rank (0.44%...
