Description

In this paper; the results of investigations on uranium (4) extraction from industrial solutions of phosphoric acid obtained from Florida phosphorite, were presented. The investigations were carried out in single stage of the centrifugal extractor with the separate drive of the mixer agitator and the centrifuge. Extractant was kerosene solution of mono- and dinonylphenyl phosphoric acids. The suspension from the acid was removed by the sedymentation, filtration and clarification with mineral-carbon adsorbent. Obtained extraction efficiency reached the level of 13--15, 6%
