Process for ferruginous sulphide calcining, essentially characterized in that it is subjected to a process of calcination of the sulfide mineral with a free oxygen containing gas and separating the slag from the calcination gas, carrying out the calcination operation at a suitable temperature and with an adequate volume of free oxygen, containing gas that the slag, will be presented, in whole or in part, as magnetite, subliming an appropriate amount of sulfur and after the separation of the slag, without simultaneously condense the sulfur, increasing the partial pressure of oxygen in the hot calcination gas, complete combustión of the sulfur in said calcining gas in the absence of the slag being effected.
