Abstract
Procedure for the treatment of sulphurous iron minerals to obtain sulfur oxides and metal sulphates under the reaction of sulfur dioxide and oxygen in circuit characterized by the sulfur dioxide previously heated to more than 500º used as reaction gas and graduated to a content of oxygen between 2 and 8% volumetric reacts on the material regulating the reaction in the furnace by the temperature and composition of the gases introduced and not exceeding the material concretion temperature.
