A PROCESS FOR THE ELECTROLYTIC PRODUCTION OF A PURE AND DUCTILE MULTIVALENT METAL OF THE GROUP CONSISTING OF TITANIUM, ZIRCONIUM, HAFNIUM, THORIUM AND URANIUM, COMPRISING PASSING AN ELECTROLYZING CURRENT THROUGH AT LEAST ONE COMPARTMENT OF AN ELECTROLYTIC CELL BETWEEN A LIQUID ALLOY ELECTRODE AS CATHODE AND A SOLID ANODE IMMERSED IN A MOLTEN ELECTROLYTE CONTAINING AT LEAST ONE OXIDE OF SAID MULTIVALENT METAL IN A FUSED SOLVENT HAVING CATIONS MORE ELECTROPOSITVE THAN THOSE OF SAID MULTIVALENT METAL WITH RESPECT TO OXYGEN AND HALOGENS, SAID LIQUID ALLOY ELECTRODE CONTAINING SAID MULTIVALENT METAL AND A SOLVENT OF AT LEAST ONE OF THE GROUP OF METALS LESS ELECTROPOSITIVE THAN SAID MULTIVALENT METAL WITH RESPECT TO HALOGENS, THEREBY DISCHARGING OXYGEN AT SAID ANODE AND DEPOSITING SAID MULTIVALENT METAL IN SAID LIQUID ALLOY CATHODE, SIMULTANEOUSLY PASSING AN ELECTROLYZING CURRENT THROUGH ANOTHER COMPARTMENT OF SAID ELECTROLYTIC CELL BETWEEN SAID COMMON LIQUID ALLOY ELECTRODE AS ANODE AND A SOLID CATHODE IMMERSED IN A FUSED ELECTROLYTE CONTAINING AT LEAST ONE HALIDE OF SAID MULTIVALENT METAL AS A SOLUTE IN A SOLVENT
