The extraction of U (Ⅵ) from rich uranium leaching solution by N235, mixed alcohols and sulfonated kerosene was studied. The influence of several variables on the extraction rate of uranium, including the N235 volume fraction, phase ratio (A/O) and equilibrium time was investigated. The results show that the extraction rate is 99.92% when the volume ratio of N235, mixed alcohols and sulfonated kerosene is 10:4:86, phase ratio is 1:2, and extracting time is 2 min. The uranium in organic phase was stripping by ammonium carbonate, and stripping rate is 99.93%. Also, the ammonium uranyl tricarbonate product was in line with national standard.
