Separating Hafnium from Zirconium. Solvent Extraction with Tributyl Phosphate
Journal Article
·
· Industrial and Engineering Chemistry
A schematic flow diagram of a possible Zr process is illustrated. Zircon sand, treated with caustic, is converted into aqueous Zr(NO₃)₄ solution and extracted with tributyl phosphate. The solvent preferentially dissolves Zr, leaving Hf in the aqueous phase. The purified Zr is stripped from the solvent with water or dilute H₂SO₄, and the solvent re-used. Zirconium sulfate is then converted to either the oxide or the fluoride, as a preliminary step in metal preparation. (W.L.H.)
