Characterization and evaluation of washability of Alaskan coals - phase iii, selected seams from the northern Alaska, Nulato, Eagle, Nenana, Broad Pass, Kenai, Beluga, and Chignik coal fieldsThis report is a result of the third part of a continuing study to obtain washability date for Alaskan coals, to supplement the efforts of the U.S. Department of Energy in their ongoing studies on washability of U.S. coals. Washability characteristics were determined for fifteen coal samples from the Northern Alaska, Nulato, Eagle, Nenana, Broad Pass, Kenai, Beluga and Chignik coal fields. The raw coals were crushed to 1-1/2 inches, 2/8 inch and 14 mesh topsizes, and float-sink separations were made at 1.30, 1.40 and 1.70 specific gravities.
