How to Remove Sulphur from Coal

Reducing the inorganic sulfur in coal to tolerable limits by physical beneficiation, including flotation, as now practiced, still is relatively inefficient and has not kept pace with the more sophisticated physical beneficiation approaches employed by the nonfuel minerals industry in general. As one phase of a broad program conducted by the Mineral Resources Institute on the sampling and
