The invention is concerned with a process for removing heavy metals and/or heavy metal compounds from the filter dust of refuse incinerators, flue gas dust precipitators and gas-cleaning units, in which the filter dust is heated in a reaction vessel at least up to the vaporisation temperature of the heavy metals and/or heavy metal compounds which are to be removed, the vaporised heavy metals and/or heavy metal compounds are then quenched in a cooler and converted to a liquid or solid state, and removed. The process of the invention is characterized in that before the vaporization of the heavy metals and/or heavy metal compounds to be removed, superfine dust particles with a particle size smaller than 5µm are separated in a cold state from the filter dust by mechanical, hydraulic or pneumatic means or by filtration, and the remaining filter dust fraction is fed to the reaction vessel.
