FIELD: metallurgy.
SUBSTANCE: method for extracting rare-earth elements from the technological and productive solutions containing iron (III) and aluminium, with a pH-0.5÷2.5, includes the sorption of rare-earth elements with strong-acid cation resin. As the strong-acid cation resin the microporous strong-acid cation resin is used based on hypercrosslinked polystyrene having a size of micropores 1-2 nm.
EFFECT: higher efficiency of the process due to greater sorption capacity of the said strong-acid cation resin, high kinetics of sorption and selectivity, improvement of the subsequent quality of eluates and simplification of the process of their further processing.
