Independent Claim
134 words
THE METHOD OF MAKING A MATERIAL SELECTED FROM THE GROUP COMPRISING DRY ALKALI METAL CHLOROTITANATES AND AMMONIUM CHLOROTITANATE FROM TITANIUM-BEARING MATERIALS COMPRISING THE STEPS OF: MIXING SAID MATERIAL WITH AN ACID SELECTED FROM THE GROUP CONSISTING OF SULFURIC AND A MIXTURE OF HYDROCHLORIC AND SULFURIC TO FORM A TITANIUM SOLUTION; SEPARATING SAID TITANIUM SOLUTION FROM THE UNDISSOLVED MATERIALS THEREIN; TREATING SAID TITANIUM SOLUTION WITH HYDROGEN CHLORIDE GAS; ADDING A MATERIAL SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL CHLORIDES AND AMMONIUM CHLORIDE WHEREBY A MATERIAL SELECTED FROM THE CLASS CONSISTING OF ALKALI METAL CHLOROTITANATE AND AMMONIUM CHLOROTITANATE IS PRECIPITATED; SEPARATING SAID PRECIPITATED CHLOROTITANATE FROM THE SUPERNATANT SOLUTION AND DRYING SAID CHLOROTITANATE TO LESS THAN 0.03% MOISTURE RETENTION BY PASSING HYDROGEN CHLORIDE GAS THERETHROUGH WHILE MAINTAINING SAID CHLOROTITANATE AT A TEMPERATURE 20* TO 300* CENTIGRADE.
