520 $a A process for removal of heavy metals from municipal solid waste (MSW) incinerator fly ash was studied on a laboratory scale. The process is characterized by the formation of volatile chlorides of heavy metals during thermal treatment at temperatures from 600 $\ sp\circ $\ sp\circ $\ sb2 $ was found to be a more selective chlorinating agent compared to Cl $\ sb2 $ for volatilizing the above heavy metals from a complex matrix such as fly ash. A linear relationship between the efficiencies of volatilization of the partially recovered metals and their standard free-energy changes for the chlorination reactions was indicated. Many of these chlorination reactions were found to be of first order. X-ray powder diffraction was used to identify various chemical compounds to confirm specific reaction mechanisms and to characterize the volatile matter and the heat-treated/untreated fly ash. The reason for the unexpected leachability of Cr and Al from the treated ash residue was investigated and resolved. The applicability of the results to other residues was determined. The techniques developed for the MSW fly ash were applied to a steel dust waste with success for removal of zinc and lead contaminants.
