Characterization and Evaluation of Washability of Alaskan Coal: Selected Seams from Northern Alaska, Chicago Creek, Unalakleet, Nenana, Matanuska, Beluga, Yentna, and Herendeen Bay Coal Fields. Final Technical Report for Phase IV,

摘要

Washability characteristics were determined for fifteen coal samples from the Northern Alaska, Chicago Creek, Unalakleet, Nenana, Matanuska, Beluga, Yentna and Herendeen Bay coal fields. The raw coal was crushed to 1 1/2 inches, 3/8 inch and 14 mesh top sizes, 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 yields given. The coals were mostly subbituminous and bituminous. (ERA citation 08:019615)
