EFFECT OF BORIC ACID ON THE EXTRACTION OF BASTNASITE LEACHING LIQUOR BY CYANEX 923

  

Abstract: The effect of boric acid on the extraction of bastnasite leaching liquor by Cyanex 923 was studied. Boric acid wasnt extracted alone by Cyanex 923 and didnt influence the cerium(IV) extraction. But it can enhance the extraction of hydrofluoric acid evidently and came into organic phase in form of (HF)(H3BO3).(Cyanex 923).
