Solid waste from coal cleaning poses a significant environmental problem. In this work, the waste is stabilized by aggregation and sintering to form impervious, vitreous granules. The result is an inexpensive method for eliminating dusting, leaching, and smoldering at waste disposal sites. The process utilizes the fuel and sintering materials inherently present in the waste which, in this study, came from the River King Coal Preparation Plant, in Freeburg, IL where the coal and waste are similar to those from Iowa mines. Characterization and grinding of the waste, the formation and testing of green pellets for strength and durability, the design and operation of a fixed bed sintering furnace, and preliminary evaluation of the sintered granules formed are discussed.
