Relationship between major inorganic elements and minerals in coals from the Ashibetsu district, Ishikari Coal Field, Japan

Information from both mineralogical and elemental analyses of coal is important for coal utilization technologies such as combustion, gasification, liquefaction, and coking, as well as for environmental considerations. The analyses have often been carried out separately. However, a combination of both analyses would bring more fruitful results than separate analyses concerning the nature of the mineral matter in coal. Two methods of coal sample collection for both analyses are available: collection of various kinds of coal samples on rank from different locations and collection of coal samples from different coal seams at the same location. The former method provides a wide range of information on coal mineral phases and elements and the latter provides precise specification of coal mineralogical and elemental characteristics. The goal of this study was to explore the relationships between major inorganic elements and mineral-phases in coals by analyzing samples from different coal seams in the Ashibetsu district, Ishikari coal field, Japan. The geochemical implications of mineral abundances were previously reported.
