Samples of feed coal, clean coal product, and refuse from three commercial coal preparation plants have been processed to yield samples for chemical and mineralogical analysis, physically characterized using screens and float-sink gravity separations, and submitted for extensive chemical analyses. Data collected from this work is being reported as it is available. This report presents a variety of data collected during characterization of the Pocahontas No. 3 sample (southern West Virginia) collected at the District Seven Preparation plant. Calcomp plots of washability data, the screen analysis of the raw coal, a large part of the chemical data obtained from the screen and gravity fractions, and the washability analysis itself are presented. Further characterization of the Pittsburgh sample included correlations between maceral groups, macerals, and mineral matter in head and float-sink fractions. Qualitative mineral distribution trends were also identified for head samples from the Pittsburgh and Pocahontas No. 3 seams using IR. Additional work performed on equipment in the pilot-scale preparation plant to optimize jigging capability is discussed.
