Abstract
Glass and metal are recovered separately by melting from the solid residues produced in a refuse incineration plant, particularly from slag. The melting is effected in two zones. In the first, top melting zone the oxidic constituents of the residues are converted into a glass melt. In the second, bottom melting zone the metallic constituents of the residues are converted at a higher temperature into a metal melt. The two melts are recovered separately.
