A two step method of converting ferrous chloride from a pickling liquor to produce hydrochloric acid and ferric sulfate is disclosed. The ferrous chloride is first mixed with sulfuric acid to produce ferrous sulfate and HCl. The HCl is carried to an absorbtion tower where most of the HCl is collected and the remainder is returned to the reactor.
