A method of and an apparatus for the desulfurization of the flue gases from a fossil fuel power plant. A particulate absorbent is contacted with the flue gases in a dry desulfurization step, particulates being then separated from the flue gas and being utilized in part as a secondary absorbent in a subsequent scrubbing of the flue gas. The sludge from the wet scrubbing is combined with the remainder of the dried particles from the separator to form a settable composition.
