  • Stabilization of heavy metals in ash
    Patent number: 5649895
    Abstract: This invention relates to a process for stabilizing heavy metals in ash. The steps of the process include: (a) preparing an aqueous slurry of ash and water; (b) decreasing the pH of the aqueous slurry to less than about 5.0 in the presence of an iron salt; (c) treating the aqueous slurry with (1) an organo sulfur containing compound, (2) an alkaline extract of peat moss, and (3) an alkaline earth metal containing compound.
