The highly alkaline residue from the fluidized-bed combustion (FBC) of coal may be an environmentally acceptable material for use in neutralizing acid produced by the oxidation of pyrite in coal slurry solids (CSS). Previous research indicated that FBC residues in mixtures with pyrite-rich CSS neutralized the acid produced by or attenuated the oxidation of pyrite in CSS. In the present research we intend to collect cores of unconsolidation material and sample pore gases from a reclaimed coal slurry impoundment. The data gathered will provide background information necessary for the development of a predictive computer model of the generation and migration of acid in a reclaimed coal slurry impoundment. The conceptual model for the oxidation of pyrite at near-neutral conditions has been revised. The model is being built around the method of Morel and Hering (1993) and Westall (1986).
