Initial new findings show significant features of coal microstructure and are related to understanding the process of coal formation and consolidation. These can be exploited to offer improvements in sulfur removal. As pyrite (Fes,) constitutes the major source of sulfur in coal, a description of the occurrence of pyrite in the coal in terms of size, morphology, and distribution is developed utilizing information from combined SEM-ED X- ray analysis. The interrelation of macerals· (coal constituents) and inorganic phases is characterized, and on the basis of the identification of useful features of the ultrafine structure of the various coal constituents, these may be related to the development and application of innovative comminution and beneficiation techniques.
