Improvements in the procedure to obtain di-oxisulforous gases by stepped testing of materials containing roasted sulfur and arsenic in swirling layers, obtaining roasting residues practically free of arsenic, object of the main patent, being characterized by the oxygen necessary for the The feed is fed to the different swirling layers in the form of fresh gas separately and independently from each other and the roasting gas formed in the first swirling layer is evacuated separately from the test gas which is formed in at least the next swirling layer which it is further characterized by the fact that during the roasting of pyrites, the oxygenated gases, especially air, and pyrites are fed to the first swirling layer in such a proportion that a roasting gas with a content of approximately 20% by volume of dioxide is obtained. sulphide and a previous test material that in addition to the gangue is Compose of ferrosulfide or ferrosulfide and iron disulphide.
