ABSTRACT:
A process for the purification of flue gases by wet methods in which the inert part of the flue gases are separated from acidic pollutants by leaching with the acidic agents of the washing liquid to which recovered flue dust has been added. The leached toxic pollutants are then extracted from the washing liquid by appropriate treatment of the discharge of the recycling circuit.
