1. A method for separating a waste material, the waste material comprising at least one metal and at least one organic material, the method 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 maximum copper content of 0.1 wt % to 20 wt %,
charging of a reactor with the separated fraction,
introducing gas containing oxygen into the reactor as an oxidant and combusting the separated fraction in a combustion process,
melting the separated fraction into at least one liquid slag phase and into at least one liquid metal-containing phase using a 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, and
conducting at least one portion of a combusted flue gas out of the reactor, conducting the at least one portion of the combusted flue gas into a thermal post-combustion plant and post-combusting the at least one portion of the combusted flue gas.
