A method for separating a waste material , the waste material comprising at least one metal and at least one organic material , comprising the steps: - provisioning a separated fraction of the waste material , which separated fraction is isolated from the waste material in the course of a mechanical preparation operation and which comprises the at least one metal and the at least one organic material , which separated fraction essentially comprises briquettes produced from the waste material , and optionally a coarse fraction of the waste material or a coarse fraction of another waste material and which separated fraction has a calorific value of 5 MJ/kg to 30 MJ/kg and a copper content of 0.1 wt% to 20 wt%, - continuous or discontinuous charging of a reactor with the separated fraction , - introducing gas containing oxygen into the reactor as an oxidant and combusting the separated fraction in an incomplete combustion process, - melting the separated fraction into at least one liquid slag phase and into at least one liquid metal-containing phase using the thermal energy generated during the combustion of the separated fraction , - pouring off the at least one slag phase and/or the at least one metal-containing phase from the reactor , - conducting at least one portion of an incompletely combusted flue gas out of the reactor , conducting the at least one portion of the incompletely combusted flue gas into a thermal post-combustion plant and post-combusting the at least one portion of the incompletely combusted flue gas . - provisioning a separated fraction of the waste material , which separated fraction is isolated from the waste material in the course of a mechanical preparation operation and which comprises the at least one metal and the at least one organic material , which separated fraction essentially comprises briquettes produced from the waste material , and optionally a coarse fraction of the waste material or a coarse fraction of another waste material and which separated fraction has a calorific value of 5 MJ/kg to 30 MJ/kg and a copper content of 0.1 wt% to 20 wt%, which separated fraction is isolated from the waste material in the course of a mechanical preparation operation and which comprises the at least one metal and the at least one organic material , which separated fraction essentially comprises briquettes produced from the waste material , and optionally a coarse fraction of the waste material or a coarse fraction of another waste material and which separated fraction has a calorific value of 5 MJ/kg to 30 MJ/kg and a copper content of 0.1 wt% to 20 wt%, - continuous or discontinuous charging of a reactor with the separated fraction , - introducing gas containing oxygen into the reactor as an oxidant and combusting the separated fraction in an incomplete combustion process, - melting the separated fraction into at least one liquid slag phase and into at least one liquid metal-containing phase using the thermal energy generated during the combustion of the separated fraction , - pouring off the at least one slag phase and/or the at least one metal-containing phase from the reactor , - conducting at least one portion of an incompletely combusted flue gas out of the reactor , conducting the at least one portion of the incompletely combusted flue gas into a thermal post-combustion plant and post-combusting the at least one portion of the incompletely combusted flue gas . <EOS>
