Research continued on this program to relate beneficiation characteristics of ultra-fine coals to the mineral-matter liberation and bulk properties of the coals. Washability tests are reported here which quantify mineral-matter liberation during ultra-fine grinding of Pittsburgh, Pocahontas No. 3, Sunnyside, Anderson and Beulah-Zap coals. The first three are bituminous coals from Pennsylvania, West Virginia and Utah, respectively, and the last two are a subbituminous coal from the Powder River area of Wyoming and a lignite coal from North Dakota. 4 refs., 5 tabs.
