ABSTRACT:
Process of treating filter dust (3) of the type produced in aluminium recycling processes in a recycling system for recycling the metal (1) of salt slag recycling (2), including at least a pyrolysis step (31) in which the filter dust (30) enter a rotating auger where it is heated to a temperature of not less than 500° C. and not more than 600° C.; and in which the organic and toxic substances breakdown in this heating and part of the carbon and other combustibles burn in the controlled presence of air, this air being mixed with the dust by the movement of the rotating auger (310); in which organic materials are oxidized due to the oxygen provided; and in which the solid result of the pyrolysis step (31) is added to the general salt slag recycling process (2).
