Abstract
During the combustion of fossil fuels, sulfur oxide compounds are formed and released to the atmosphere. If it were feasible to physically remove pyrite from coal in significant quantities, the amount of sulfur oxide produced from coal firing could be reduced. The objective of the work was twofold; first, to extend the washability data to finer sizes of coal, and second, to evaluate coal cleaning methods and techniques for removing pyritic sulfur from the fine-sized coal. From previous work with pyrite removal from finely sized coal, two size consists were of interest in the washability studies: The 30 mesh x 0 size; and Each coal's 'as fired,' or p.c. grind. During evaluation of the pyrite liberation and removal characteristics of seventy different utility coals when pulverized to a topsize of 30 mesh and to the coal's p.c. grind, an extensive quantity of information has been generated. The results of the coal cleaning tests with the concentrating table were, in general, excellent. A wide range in sulfur reduction was obtained in the Majac air classification tests. (Author)
