ABSTRACT:
A garbage incinerator is provided with a system for collecting the grate ash, the boiler ash and the fly ash resulting from the incineration and the collected residue is fed to a melting furnace from which the metal and metal compounds are recovered in the form of a metal-enriched melt and a slag which can be granulated and used in highway construction or the like since it is completely glassy. The metal-enriched melt can also be treated to recover metals therefrom.
