OSTI ID:4835100
An improved process is outlined for separating Zr and Hf by solvent extraction. The process comprises distributing Zr and Hf oxychlorides between an aqueous chloride ion-containing solution (usually 2 to 13 N HCl) and a halogenated hydrocarbon (e.g., chloroform) containing an organic amine (e.g., tribenzylamine) at 20 to 60 deg C. One advantage of the process is that Zr oxychlorides obtained from dressing of Zr ores can be used directly. (D.L.C.)
