Abstract:
A method for treating fly ash from incineration plants having at least one combustion chamber includes precipitating fly ash in a dust separator, and treating the fly ash using a gaseous reducing agent at a temperature between 600 and 700° C. so as to selectively convert a metal sulfate into at least one of a sulfide and a metallic form of the metal sulfate.
