Abstract
A process for roasting pyrite in phases, taking advantage of the distillation phase and the processes that take place outside the roasting process, such as obtaining steam, the heat produced in the roasting phase, as well as that produced in the combustion of the sulfur vapor from the distillation phase, characterized in that the combustion of the sulfur vapor from the distillation phase is carried out by the residual oxygen contained in the hot roasting gas and in special chambers, while the The distillation phase is fed with the heat necessary for the expulsion of the distillable sulfur part of the pyrite, by heating by irradiation from said chambers.
