dc.description.abstractTwo samples of low-volatile bituminous coal from Bering River Coal Field were sized to 0.525" x 3, 3 x 6, 6 x 10, 10 x 20, and 20 x 35 mesh and their washability characteristics studied at specific gravities ranging from 1.29 to 1.55. The results showed that the coals can be up-graded to an ash content as low as 2% with conventional cyclone heavy media process. A product containing less than 1% ash can be obtained from these coals with surprisingly high yields, ranging from 50 to 95% depending on the ash content desired in the washed coal, and the characteristics of the raw coal. The experimental work proves the technical feasibility of preparation of the coal form metallurgical use and as low ash carbon raw material. Further Pilot Plant testing would be required in the fields of preparation and utilization in order to design the final plant for ascertaining the economic feasibility.en_US
