Abstract

The invention concerns a combined method for purifying fume contaminated by hydrogen chloride and heavy metals, rendering inert the heavy metals and upgrading the hydrogen chloride, which consists in: subjecting the fume (6) to a treatment, by dry or semi-humid process, with a basic reagent (8) comprising a soda compound; collecting from said treatment a solid residue (13) containing the heavy metals; dispersing the solid residue and a hydraulic binder (18) in water (20) to form an aqueous broth (21); and extracting from the broth the solid mass (28) which is eliminated, and an aqueous solution (29).
