Summary: | A method for obtaining non-ferrous metals, in particular black and/or raw copper, from scrap containing organic matter, comprises the following steps: i) providing a melting reactor, wherein the melting reactor includes a melting region, a combustion region and a pyrolysis region; ii) supplying the melting reactor with a mixture comprising the scrap such that it first passes through the pyrolysis region and the combustion region before it reaches the melting region, and is at least partially pre-pyrolyzed and/or combusted, such that an energy-containing gas stream is formed; iii) transferring the energy-containing gas stream into a thermal post-combustion chamber, in which the energy-containing gas stream is completely combusted and thermal energy released during combustion is carried off via an energy recovery unit; and iv) melting the scrap containing organic matter at least part of which has been pre-pyrolized and/or combusted. |
