THE PROCESS OF REMOVING TITANIUN AS TITANIUM TETRACHLORIDE FROM ILMENITE ORE WHICH COMPRISES HEATING THE ORE TO A TEMPERATURE ABOVE 1250 DEGREES C. BUT BELOW 1500 DEGREES C., SEPARATELY HEATING CHLORINE TO A TEMPERATURE ABOVE 1250 DEGREES C. BUT BELOW 1500 DEGREES C. THEN BRINGING THE CHLORINE AND ORE TOGETHER IN A REACTION CHAMBER AND MAINTAINING THE TEMPERATURE THEREOF DURING REACTION IN THE RANGE BETWEEN 1250 DEGREES C. AND 1500 DEGREES C. AND DRAWING OFF THE GASEOUS PRODUCTS OF REACTION FROM THE SOLID RESIDUE WHILE THE RESIDUE IS WITHIN SAID TEMPERATURE RANGE, THEREBY SELECTIVELY REMOVING THE TITANIUM COMPONENT OF THE ORE AS TITANIUM TETRACHLORIDE IN THE EFFLUENT STATE FROM THE SOLID RESIDUE AND LEAVING THE IRON COMPONENT OF THE ORE UNCHLORINATED IN THE SOLID RESIDUE UNTIL THE DRAWN OFF GASEOUS PRODUCTS CONTAINING THE TITANIUM TETRACHLORIDE ARE SEPARATED FROM THE SOLID RESIDUE.
