ABSTRACT:
The invention concerns a means for separating molten particles from the exhaust gases of metallurgical furnaces and for returning them to the furnace space (3). As taught by the invention, a molten dust cyclone has been provided substantially within the furnace space (3) or in its immediate vicinity, this cyclone comprising a vertical cylindrical chamber (4), a passage (8) leading from the furnace space (3) tangentially to chamber (4), an exit aperture (5) in the upper part of the chamber for removing the gas and a tap aperture (6) in the lower part of the chamber for returning to the furnace space (3) the solid and molten material that has separated from the gas.
The invention furthermore concerns a way recover lead from the exhaust gases of a metallurgical furnace by regulating the oxygen partial pressure in the exhaust gases to be in the range of about 10.sup.-16 to 10.sup.-10 atmospheres at temperature 1250.degree.-1450.degree. K. and by subjecting the exhaust gases immediately to centrifugal separation to the purpose of separating lead fog droplets from the gas to the purpose of returning the molten lead to the furnace.
