Summary:The present invention relates to a method for obtaining non-ferrous metals, more particularly black and/or raw copper, from scrap containing organic matter (8), comprising the steps: i) providing a melting reactor (2), the melting reactor (2) being configured such that it has at least one melting region (5), a combustion region (6) and a pyrolysis region (7), ii) supplying the melting reactor (2) with a mixture comprising the scrap containing organic matter (8) such that said scrap containing organic matter first passes through the pyrolysis region (7) and the combustion region (6) before it reaches the melting region (5) and is at l;east partially pre-pyrolised and/or combusted such that an energy-containing gas stream (9) is formed, iii) transferring the energy-containing gas stream (9) into a thermal post-combustion chamber (3), in which the energy-containing gas stream (9) is completely combusted and the thermal energy released during combustion is carried off via an energy recovery unit (11), and iv) melting the scrap containing organic matter (8) at least part of which has been pre-pyrolised and/or combusted.
