During the past year, progress was made in the development and improvement of several promising methods for the desulfurization and recovery of fine-size coal. The methods include froth flotation, selective oil agglomeration, pelletization, and a unique chemical desulfurization process based on leaching the fine coal with a hot dilute solution of sodium carbonate containing dissolved oxygen under pressure. The latter is a form of wet oxidation process which converts both organic and inorganic sulfur into soluble sulfates. Progress in the various methods is described.
