摘要
Abstract
The fractional extraction separation of uranium and vanadium in acidic leaching solution of a uranium-vanadium ore was studied.The separation process of solvent extraction of uranium using N235 and solvent extraction of vanadium using P204 was determined.The influence of extraction agent concentration,aqueous pH,temperature,contact time,the ratio of organic phase-to-water phase on solvent extraction of uranium and vanadium were examined.By the process,the stripping solution of uranium contains no vanadium and stripping solution of vanadium has less than 1 mg/L uranium, uranium is high efficient separated from vanadium in acidic leaching solution of uranium-vanadium ore.关键词
