(NL1009412-C2)   NOVELTY - Metal-containing waste including organic material is pyrometallurgically processed in furnace chamber by blowing reducing gas at high velocity onto its molten surface. Steam and/or oxygen-rich gas are also injected parallel to the surface of the smelt.    USE - For extracting metals, such as zinc, cadmium, lead, and tin, from pyrolyzed waste material or material such as sewage sludge.    ADVANTAGE - The process is able to effect complete combustion of the carbon floating on the surface of the smelt and any other organic material. The fuel gas discharged from the furnace still has considerable calorific value and contains volatilized metals or metal compounds which can be removed. Only slags of inorganic materials will remain in the furnace for tapping off right at the bottom of it.
