Washability Examinations of Wyoming Coals.
NTIS: PB 201 898 :47 pages
This Bureau of Mines report describes the washability characteristics of 14 coalbed samples collected in Wyoming. Such data is needed to evaluate the quality of the coals of the west where most of our low-sulfur-content coal reserves are found. Of the 14 samples included in this report 13 had a total sulfur content of 1.1 percent or less. All of the samples contained low percentages of ash or could be readily washed to a desirable ash level with minimal loss of yield. The coals ranged in rank from high-volatile b bituminous to subbituminous c, although 10 of the samples were high-volatile c bituminous. The coalbeds varied in thickness from 4.5 To an unknown thickness greater than 67.5 Feet.
