Three tasks are being conducted in this research project. All are related to understanding the chemistry and mineralogy of the co- disposal of fluidized bed combustion (FBC) wastes with coal slurry solid (CSS) from a coal preparation plant. During coal cleaning, pyrite and other heavy minerals and rock materials are rejected from the coal and discharged in an aqueous slurry to an impoundment. Soluble components and acid-base reaction products from mixtures of fluidized bed combustion (FBC) wastes and coal slurry solids (CSS) are being extracted in aqueous solution in a series of batch experiments. These experiments are being conducted in order to provide information on the solution chemistry associated with the mixtures over an extended time. Large volumes of extracts from three mixtures of FBC waste and CSS are being prepared for use in experiments to ascertain the adsorption/desorption reactions that occur between components of the extracts and three commonly occurring Illinois soils. A computer program that simulates the effects of pyrite oxidation and acid neutralization in a spoil heap is being corrected and improved.
