<p>In a process for implementing reducing pyrometallurgical processes with oxyde ores, concentrates, intermediate products or metallic intermediate products by means of strongly reducing gases or oxygen-containing gases for producing and refining a molten metal, the reducing gas is injected at a speed greater than 100 m/s and less than 300 m/s through at least three nozzles onto the surface of a charge located in a cylindrical axial cavity of a furnace. The ascending gas, which has a high CO and H2 content, is deviated at the point of impact and burnt again in the cylindrical cavity of the oven by the air injected into the latter according to a secant.</p> |
