Description:"The Bureau of Mines investigated two alternative methods for treating a zirconium-bearing chloride-sulfate strip liquor to obtain reactor-grade zro2. One method involves neutralization with nh3 and the other hydrothermal precipitation. The strip liquor was derived from zircon sand by a Bureau of Mines method for separating zirconium and hafnium via solvent extraction with a Tertiary amine. Neutralization with nh3 to precipitate hydrous zirconium oxide required 0.9 to 1.1 G nh3 per gram of zirconium. The nh3 can be recovered for recycle. Zro2 that met reactor-grade specifications was produced by precipitation with nh3. Hydrothermal precipitation of zro2 from strip liquor required that the solution be maintained at 260 deg c and 680 psi for 10 min and in a noncorrodible pressure vessel. In bench-scale experiments both methods gave zirconium recoveries greater than 99 pct." - NIOSTHTIC-2
