WASHABILITY EXAMINATIONS OF CORE SAMPLES OF SAN JUAN BASIN COALS, NEW MEXICO AND COLORADO
This report describes the washability characteristics of 18 coal samples taken from 11 drill hole cores from the San Juan Basin area of New Mexico and Colorado. The ash content of these coals could generally be substantially reduced by removing the heavy impurities. The coals were characteristically low in sulfur content; only one sample contained more than 1 percent sulfur after removing the sink 1.50 specific gravity material. The coals ranged in rank from subituminous C to high volatile C; 11 of the samples were subituminous A. Many of these core samples came from areas where very little fieldwork has been done; consequently, an outgrowth of this work has been an increase in known coal reserves of the San Juan Basin area.
