Abstract: A method for obtaining metals of the 8th to 14th groups, in particular raw copper, comprises the following steps: i) providing and melting down a mixed feed comprising electronic waste in a smelting reactor, so that a first melt with a first metallic phase and a first slag phase is formed; ii) separating out the first slag phase from the smelting reactor; iii) refining the remaining first metallic phase by means of an oxygen-containing gas, possibly with the addition of copper-containing residual materials, so that a second, copper-enriched slag phase is formed; iv) possibly separating off the second slag phase and repeating the step; v) separating off the refined first metallic phase from the smelting reactor; and vi) adding a further mixed feed comprising electronic waste to the remaining second, copper-enriched slag phase and repeating process steps i) to vi).

Abstract: The present disclosure relates to a method for the pyrometallurgical smelting of metal-containing raw materials, waste materials and/or secondary waste materials (M), wherein these are fed in shredded form to a smelting unit (1) which includes a smelting zone (6), a main reaction zone (7) and a secondary reaction zone (8) and are smelted in the presence of an oxidizing, reducing and/or inert gas and/or gas mixture (G), such that a liquid melt phase (9), a liquid slag phase (10) and a gas phase are formed. The oxidizing, reducing and/or inert gas and/or gas mixture (G) is supplied in compressed form via at least one injector (11) and is expanded adiabatically within the smelting unit (1) and is then injected as adiabatically expanded gas and/or gas mixture into the liquid slag phase (10).

Abstract: 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.
