Abstract

PURPOSE:To obtain the titled substance, by extracting Nb and Ta from a mixed solution containing metal impurities such as Na and Ta, subjecting Nb and Tb to back extraction with water, removing Ta with an adsorbent, adding KOH or HF to give Nb sediment, dissolving the Nb sediment in an acid and treating the solution with an alcohol. CONSTITUTION:A mixed solution of hydrofluoric acid and sulfuric acid containing metal impurities such as Nb and Ta is brought into contact with an organic solvent such as ketone diluted with a petroleum hydrocarbon to extract Nb and Ta, which are subjected to back extraction with water, Ta is removed with an adsorbent, KOH and KF are added to an aqueous solution containing Nb to give sediment containing Nb, K<+> and F<->. Then the sediment is dissolved in an acid to give a solution, which is adjusted to proper pH, is brought into contact with an oxygen-containing solvent, Nb ion is extracted as a halogenated metal complex water is removed, an alcohol and then a NH3 gas are added to the organic solvent from which water is removed to give the aimed substance and to regenerate the oxygen-containing organic solvent. In this method, expensive metal Nb is not used as a starting raw material.
