<p>The method of melting oxidic slags and combustion residues with a minimum content of 3 % by weight of metallized components, such as iron and/or carbon carriers, is carried out in a shaft furnace (1) that is directly heated via burners (4) by means of fossil fuels. The molten slag bath (13) is transferred to a hearth furnace (16) directly connected to the shaft furnace (1); here, metals such as copper are separated by sedimentation under thermal dissociation, and withdrawn separately through a bottom outlet (19). The fully oxidized slag passes through a separate outlet (20) into a downstream slagtreatment reactor.</p> |
