FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgy, in particular, to the method for extraction of europium (III) from salt solutions by floating extraction. In process of floating extraction of europium (III) cations the organic phase is represented by isooctyl alcohol, and the collector of surfactants of anion type is sodium sodium dodecyl sulfate in the concentration corresponding reaction stoichiometry: Eu+3+3NaDS=Eu(DS)3+Na+, where Eu+3 - cation of europium (III), DS- - dodecyl sulfate-ion. At the same time the floating extraction is carried out at pH=7.5-8.5, and at the ratio of organic and water phases 1/20-1/40.
EFFECT: increased extent of europium (III) extraction.
