Coal cleaning wastes are ground, granulated and sintered to form vitreous, impervious granules capable of disposal without dusting, leaching or smoldering. The process utilizes the energy inherently present in the wastes. Characterization and grinding of the wastes, the formation and testing of green granules for strength and durability, the firing of the granules in a large tube furnace to approximate sintering in a traveling grate furnace, and evaluation of the sintered granules by means of standard leaching and freeze-thaw tests are discussed. 10 refs., 6 figs., 6 tabs.
