Abstract: Part 1 of the present work introduced and evaluated a new approach for the combined chemical and mineral classification of the inorganic matter in coal. The benefit of this new classification approach is the use of significant correlations and actual element associations, and well defined and genetically described mineral classes and species in coal. Some potential applications of the chemically and mineralogically categorized coal types and subtypes are discussed in the present part 2. The results show that various applications and technological problems of coal such as correlation of different coals, prospecting and recovery of valuable compounds, coal preparation, as well as prediction of combustion residues, slagging, abrasion, corrosion, and combustion performance are related directly or indirectly to specific mineral and chemical coal types and subtypes. Furthermore, some environmental risks and health concerns of coal use, namely acid-mine drainage, water-soluble trace elements, volatilization of hazardous elements, and certain diseases also may be connected with specific mineral and chemical coal types and subtypes. A concept of ¿self-cleaning fuels¿ is also introduced and developed herein based on mineral coal types. The application of these classifications is proposed to both the scientific and industrial community.
