Surface magnetic enhancement for coal cleaning. Quarterly technical progress report no. 11, August 1, 1990--October 31, 1990
The fundamental chemistry for selective adsorption of magnetizing reagent on coal-associated minerals to enhance the magnetic susceptibilities of minerals have been established in Phase I study. The application of the results to study the feasibility for coal cleaning has been completed in the Phase II study. The most effective approach to clean Illinois No. 6, Ohio Lower Kittanning, and West Virginia Pocahontas coals using the magnetizing method has been determined. Phase III study is in progress during this quarter. Experimental work includes the determination of various separation parameters, including the separator and matrix selection, magnetic reagent dosage, particle size, magnetic field intensity, and retention time.
