THE METHOD OF RECOVERING TITANIUM IN THE FORM OF A HIGH-PURITY METALLIC PRODUCT FROM CRUDE TITANIUM-BEARING MATERIAL WHICH COMPRISES CONTACTING A GASEOUS PRODUCT COMPRISING TITANIUM TETRAIODIDE AND TITANIUM TRIIODIDE WITH A HEATER REFRACTORY SURFACE MAINTAINED AT A TEMPERATURE IN THE RANGE 1100* C. TO 1700* C. TO EFFECT DISSOCIATION OF THE TITANIUM TETRAIODIDE AND THE TITANIUM TRIIODIDE WITH THE PRODUCTION AND DEPOSITION OF METALLIC TITANIUM ON THE REFRACTORY SURFACE AND THE PRODUCTION OF A GASEOUS PRODUCT COMPRISING ELEMENTAL IODINE, REACTING THE ELEMENTAL IODINE THUS PRODUCED WITH TITANIUM CARBIDE AT A TEMPERATURE OF ABOUT 1100* C. TO FORM A GASEOUS PRODUCT CONTAINING TITANIUM TETRAIODIDE, REACTING THE TITANIUM TETRAIODIDE THUS PRODUCED WITH METALLIC TITANIUM AT A TEMPERATUR IN THE RANGE 600* C. TO 1100* C. TO CONVERT A PORTION OF THE TITANIUM TETRAIODIDE TO TITANIUM TRIIODIDE, AND PASSING THE REGENERATED TITANIUM TETRAIODIDE AND TITANIUM TRIIODIDE IN CONTACT WITH THE REFRACTORY SURFACE OF THE PRODUCTION AND DEPOSITION OF ADDITIONAL METALLIC TITANIUM.
