- Аннотация: The possibility of using 5-(diphenylphosphoryl)hexan-3-one as an extractant for effi cient recoveryof rare-earth metals (REM), as well as uranium(VI) and thorium(IV) from breakdown phosphogypsum solutionswithin a single technological extraction process was demonstrated. 5-(Diphenylphosphoryl)hexan-3-one as anextractant was compared in terms of effi ciency with commercially available TBP and TOPO. It is shown that thecomplete recovery of rare earth metals into the organic phase is achieved in three stages of depletion. There occursan extraction purifi cation of total rare earth metals from uranium(VI) and thorium(IV). The separation factor duringextraction for U(VI) and ΣREE was f[ΣREE/U(VI)] > 3000, and in the case of thorium(IV), f[ΣREE/Th(IV)]~10000. 5-(Diphenylphosphoryl)hexan-3-one can be successfully used in the extraction processing of mineral andtechnogenic raw materials, which enables separation and concentration of REMs.
