THE METHOD OF PRODUCING A FLUOTITANATE OF THE GROUP CONSISTING OF SODIUM, POTASSIUM AND AMMONIUM FLUOTITANATES FROM A FERRIC IRON-CONTAINING TITANIUM ORE WHICH COMPRISES HEATING THE ORE AT A TEMPERATURE OF AT LEAST ABOUT 1000*C. WITH AN AMOUNT OF A REDUCING AGENT SUFFICIENT TO REDUCE SUBSTANTIALLY ALL OF THE IRON COMPONENT OF THE ORE TO THE FERROUS STATE, COMMINUTING THE THUS-REDUCED ORE, ADDING TO THE COMMINUTED REDUCED ORE A SOURCE OF COMBINED FLUORINE FROM AT LEAST ONE OF THE FOLLOWING: ALKALI METAL FLUORIDES, ALKALI METAL FLUOSILICATES, AND MIXTURES OF ALKALI METAL FLUORIDES AND ALKALINE EARTH FLUORIDES, ADDING TO THE ORE-FLUORINE SALT MIXTURE SULFURIC ACID IN THE PROPORTION OF ONE MOLE OF ACID FOR EACH MOLE OF FETIO3 WHEN THE FLUORINE IS PROVIDED BY AN ALKALI METAL FLUOSILICATE AND IN THE PORPORTION OF ONE MOLE OF ACID FOR EACH MOLE OF FERROUS OXIDE AND ONE MOLE OF ACID FOR EACH MOLE OF TITANIA IN THE REDUCED ORE WHEN THE FLUORINE IS PROVIDED AS A FLUORIDE, REACTING THE THUS-REDUCED ORE WITH THE ADDED FLUORINE AND ADDED ACID, AND RECOVERING THE RESULTING DOUBLE FLUORIDE OF TITANIUM AND SAID ALKALI METAL.
