The Effect of Particle Size on Treating Fine Waste Generated in the Coal Preparation Plant.
Paper in Internatl Conf on Environmental Issues and Management of Waste in Energy and Minerals :8 pages
The Bureau of Mines has investigated dewatering techniques for fine coal refuse in both laboratory and field tests. Data indicate that present technology now being used in the industry will have difficulty in achieving high solids content and low polymer dosage for ultrafine waste expected from new coal-cleaning technologies. Experimental data are presented to show that dewatering of fine refuse will be difficult. The factors pertaining to these problems as well as recommendations for future research needs are discussed.
