Procedure to remove the arsenic and antimony from the residues of the calcination of sulfidic iron minerals, especially pyrite residues and for the chlorifying recovery of the non-ferrous metals contained in these residues, characterized in that the calcination residues are treated at higher temperatures at 500º, preferably at about 700 to 900º, with such halogenic compounds which simultaneously act as weak reducing agents that do not appreciably attack the iron oxide in the calcination residues.
