Characterization and Evaluation of Washability of Alaskan Coals: Selected Seams from the Northern Alaska, Nulato, Eagle, Nenana, Broad Pass, Kenai, Beluga, and Chignik Coal Fields. Final Technical Report for Phase III, March 1979-

摘要

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, 3/8 inch and 14 mesh topsizes, and float-sink separations were made at 1.30, 1.40 and 1.60 specific gravities. The results are given as follows: original percent ash, final percent ash and percent yield; in some cases the original and final percent sulfur content are given. The coals were mostly subbituminous and bituminous. (ERA citation 08:019616)
