Coal cleaning wastes are ground, granulated and sintered to form vitreous, impervious pellets capable of disposal without dusting, leaching or smoldering. The process utilizes the energy inherently present in the wastes. Fly ash and flue gas desulfurization sludge can be blended with the cleaning wastes for codisposal. Characterization and grinding of the wastes, the formation and testing of green granules for strength and durability, the design and operation of a fixed bed, batch sintering furnace, and preliminary evaluation of the sintered granules are discussed.
