A new method to characterize the complex mineralogy of ultimate wastes
- CRPG-CNRS, Vandoeuvre-les-Nancy (France)
Ultimate wastes, resulting from the incineration of municipal solid wastes, contain high amounts of toxic elements that require stabilization before storage. However, whatever the stabilization processed involved, characterization of their crystal chemistry is essential. In this paper, the authors present a method which allows the determination of the mineralogy of ultimate wastes in detail. They present here an example of results from an ultimate waste, resulting from electrofiltration of fumes. This method is based on grain size and density separations coupled with X-ray diffraction, ICP-ES, ICP-MS, wet chemical methods and electron microprobe analyses. Despite the complexity of this waste, they show that it is possible, not only to determine its mineralogy, but also to give the modal proportions of each phase, and to provide some insights into the crystal chemistry of the main pollutants of this ultimate waste product.
