PROCESS AND APPARATUS FOR SEPARATING METAL FROM FLUE DUST

摘要

Process and device for removing metal (m) from flue dust (f). The flue dust (f) is introduced into a solution (L) containing a chelating agent (c) and the metal chelate ions formed from the metal in the solution (L) are removed from the solution. This is achieved using an electrolytic cell on whose cathode the elemental metal (m) is deposited. The flue dust (f) can be flue dust (f) from the flue gas (r) of a low-temperature combustor (40).
