Abstract: A process for the production and/or treatment of at least one metal in a reactor includes discharging a waste gas stream via a waste gas conduit and after-treating the waste gas stream by supplying a cooling gas and/or a cooling gas mixture. The after-treating includes injecting the cooling gas and/or cooling gas mixture into the waste gas conduit on a side of the waste gas conduit facing the reactor, at a high velocity and substantially tangentially with respect to a main flow direction of the waste gas. A volume of the cooling gas and/or the cooling gas mixture injected into the waste gas conduit is adjusted so as to reduce a mixing temperature below a melting temperature of the molten particles and/or a condensation temperature of the vaporous constituents of the waste gas stream.
