Uranium in wet-process phosphoric acid in the tetravalent state is extracted with a mixture of mono- and di-(alkylphenyl) esters of orthophosphoric acid containing a phenol modifier such as nonylphenol or octylphenol.

Extractant and process for extracting uranium wet-process phosphoric acid

Wet-process phosphoric acid which is obtained by the acidulation of uncalcined phosphate rock with sulphuric acid and which typically contains 28-31% P.sub.2 O.sub.5 and measurable amounts of solid organic materials, such as, for example 0.1% or more, is treated to remove the solid organic materials contained therein by intimately contacting the acid with a liquid hydrocarbon so that the aqueous is the continuous phase, resulting in the solid organic materials being taken up by the organic phase.
