Study of Extraction of Uranium with Tertiary Amine for the Separation from Th and Rare Earths AITranslate
Abstract AITranslate
Monazite is leached by caustic soda. The leached residue isselectively dissolved by HCl with obtained 'selectively dissolved'residue. The later subjects to H_2SO_4 leaching and extraction. This paperdesert bes the results of study on the extraction of U from the H_2SO_4 leached solution with tertiary amine N235 for the separation from Thand rare earth. The results show that >99.5% uranium extraction yieldis obtained and ThO_2/U in the stripped U solution is (1.8-3.8) × 10￣(-3),RE_xO_y/U is (1.0-1 .6) ×10￣(-3) while U/ThO_2 in U raffinate is only(3.5-5. 6) × 10￣(-6).
