24/7 onlineProcess Of Extracting Zirconium
In one of several methods to separate hafnium and zirconium [20], hydrolysis of ZrCl 4 is followed by liquid-liquid extraction as the oxychloride (ZrOCl 2), followed by precipitation as Zr(OH) 4 and thermal decomposition to ZrO 2 The ZrO 2 is then again carbochlorinated, and the resulting ZrCl 4 used as a feedstock in the Kroll process.
