Abstract
Process for the production of metals from finely ground oxidic or sulfuric minerals, essentially characterized in that their concentration is determined by flotation and other products concentrated by endothermic system, inside an electrically heated reactor at the appropriate temperature, the reactor having a height related to the surface of the horizontal cross-section of the furnace chamber, with at least one vertical vertex without support walls remaining inside said chamber, with high-speed reaction gas being injected through at least two nozzles arranged inside the chamber of the furnace and directed tangentially with respect to a theoretical horizontal circle loading the finely divided mineral in the aforementioned vertex.
