ABSTRACT:
A process for stabilizing a substantially inorganic substrate comprises treating the substrate with sulfur at a temperature above the melting point of sulfur thus converting the substrate into a solid, inert product which resists the leaching of metals, metal ions, and other inorganic ions originally present in the substrate. Organic compounds contained in the substantially inorganic substrate are simultaneously converted to an inert carbon-sulfur polymer.
