Abstract: This paper briefly described solvent extraction test of rich uranium liquid that was obtained in granite-type uranium
leaching experiment by SZJ cataclastic-alteration, gave the material composition of raw ore and leaching rich liquid, tested the
influence of extractant concentration of uranium extraction rate in organic phase, selected the suitable phase ratio, extraction time
and the recovery rate of uranium through 4 levels consecutive extraction, an extraction washing and secondary back extraction,
which demonstrated that solvent extraction process had the advantages of technology, economy and environmental protection in
leaching of uranium ore under a certain conditions.

Key words: uranium hydrometallurgy; N235; reverse extraction; ammonium uranyl tricarbonate
