With the issuance of this report, all tasks and primary objectives of the contract have been addressed and completed, with the exception of the final report preparation, which is currently on-going. This study has attempted to examine that which complicates all phases of coal utilization, i.e., the contained minerals within the coal and the effect of coal cleaning on their distribution. Three nationally important and regionally different bituminous coals - the Pittsburgh seam, the Pocahontas No. 3 seam, and the Illinois No. 6 seam - have been studied during the course of the work, and a discussion of the final data acquisition, some of the findings, and data revisions are presented in this document. Primary emphasis was on the mineral distributions and their concurrent actions. To study this, mineral washability diagrams, mineral separabilities and other data graphics were prepared to assist in interpreting the relationships. As part of the finalization of data acquisition, a complete petrographic analysis of macerals and submacerals for the Illinois No. 6 coal was also performed. Methods and data presentation used are similar to that previously employed to allow comparisons of these three sets of coal samples.
