Abstract
Process for improving the chlorinating calcination of roasting residues of fine-grained pyrites with non-ferrous metal contents, characterized in that during the treatment of roasting residues in pure eddies, roasting pyrites roasting residues, "EGR" powders, etc., in compartment furnaces, in one or more of the middle compartments of the furnace are additionally added and distributed, fine-grained substances that cause the release, for example, flotation pyrites, powdered pyrites or pyrrhotine, or either mixtures of these, alone or mixed with sodium chloride.
