Washability examinations of core samples of San Juan Basin Coals, New Mexico and Colorado.
NTIS: PB 209 008, 1972; :1-26
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 subbituminous c to high volatile c; 11 of the samples were subbituminous a.
