Process for producing sulfur dioxide gas, free of sulfur and sulfur trioxide, from pyrite, which comprises establishing and maintaining a fluidized bed of finely divided pyrite particles in a roasting zone, passing through it a gas carrying free oxygen, at fluidization rate, reacting the particles with said oxygen at roasting temperature to give a gas containing sulfur and sulfur dioxide; discharge from the bed of toasted particles containing a minimum of 2% by weight of sulfur in the form of sulfur, supplying oxygen to the gas to convert free sulfur into sulfur dioxide and prevent over-oxidation of the gases to sulfur trioxide while maintaining traces of compounds dragged iron, as a buffer, in the gases.
