A process for recycling hot dust from a gasifier or melt-down gasifier by means of a hot gas cyclone separator integrated into a pipe system is described, together with the associated apparatus. The hot dust from the hot gas cyclone separator is supplied by means of a lock system to a burner in order to overcome the pressure difference between the hot gas cyclone separator and the melt-down gasifier. By means of the lock system the dust is supplied from a lower pressure zone to a higher pressure zone. The dust to be recycled comprises coke or a mixture of coke and iron particles.
