A study has been made of the extraction of rare earth elements (III) (praseodymium-lutetium, yttrium) by trialkylmethylammonium nitrate in kerosine (1.10 M) from binary and multicomponent solutions containing 1.0-3.0 M of ammonium nitrate. Physicochemical and mathematical models have been proposed for the distribution of individual lanthanides (III) depending on the composition of the initial raw material and on the total REE(III) and ammonium nitrate concentrations in the aqueous phase. The optimal concentration ranges for total REE and ammonium nitrate in the aqueous phase have been found for separating complex REE concentrates by using trialkylmethylammonium nitrate in the diluent.
