A PROCESS FOR CONTINOUSLY PRODUCING A POWDERED METAL SELECTED FROM THE GROUP CONSISTING OF URANIUM AND THORIUM, COMPRISING CONTINOUSLY FEEDING A COMPRESSED POWDERED MIXTURE OF AN OXIDE OF SAID METAL AND A METALLIC REDUCING AGENT IN AN INERT ATMOSPHERE SUCCESSIVELY THROUGH A COOLING ZONE, THROUGH A ZONE HEATED TO AT LEAST 500*C. TO CAUSE SAID OXIDE TO BE REDUCED TO SAID POWDERED METAL, AND THEN THROUGH A SECOND COOLING ZONE, THE RATE OF FEEDING OF SAID COMPRESSED MIXTURE BEING REGULATED SO THAT SAID MIXTURE REMAINS IN SAID HEATING ZONE FOR A TIME SUFFICIENT TO EFFECT COMPLETE REDUCTION OF SAID METAL OXIDE.
