<p>In a process for the separation of copper and heavy metals from incinerated garbage residue and slag, the residue and slag from garbage incineration or pyrolysis is heated to over 650 DEG C under reducing conditions together with substances containing chlorine or chlorides, such as flue gas cleaning residues, CaCl2 from the soda production, cooking salt, organic solvents or electroplating sludge containing chlorine, whereupon Cu-chlorides and volatile heavy metal chlorides, such as PbCl2 or ZnCl2, are drawn off in the gas phase.</p> |
