Abstract
A process for roasting sulphurous minerals, preferably pyrite, in floor furnaces, characterized in that the gas mixture flowing through the furnace is extracted approximately in the center of the furnace, at a point where the reaction I 2 FeS2 + 2 O2 = 2 FeS + 2 SO2 has just finished, being conducted, together with the exhaust gas from the top floor of the furnace, to a steam boiler, while the gas leaving said steam boiler, returns a partial current to the floor of the furnace that is located above the lower outlet of the gas, air being supplied from the outside to the same floor.
