Abstract
A process for roasting sulphurous minerals, for example, pyrite or blende, in a floor furnace, characterized in that the roasting gases formed in the floor furnace are extracted from one or more of the higher floors, being driven to a steam boiler, because part of the roasting gases, once cooled in the steam boiler, are returned directly to one or more floors of the floor furnace; because the other leg of the roasting gas is derived and used, for example, for the production of sulfuric acid, and because through the rotating hollow shaft of the floor furnace, as well as through the rake arms attached to the hollow shaft, air is conducted, which penetrates the roasting chamber through openings in the arms.
