The use of recovered waste coal fines represents an innovation to the more traditional approach of producing CWSFs from freshly mined coal. The concept of recovering these coal fines is attractive from an economic and environmental viewpoint. The use of coal pond fines as a CWSF feedstock has the potential to generate a new market for a material that is currently discarded as waste and to provide possible savings in fuel costs. In the same way that fluidized bed combustion technology has recovered fuel from bituminous and anthracite coarse refuse deposits, CWSF technology may enable the fuel contained in waste fines to be utilized.This study will evaluate four sites representing a variety of characteristics (i.e., age, active status, source of material, and composition). Site samples will be evaluated as to their cleanability and washability.
