The influence of the acidity and concentration of the rare earth elements (REE) in aqueous phase, the organic/aqueous phase ratio and the HCl concentration in stripping was estimated for the REE fractionation by solvent extraction. The assays were pe

Dynamic ion exchange has been used for rapid separation (15 min) and determination of rare earth elements (REE) in samples coming from semi-processed monazitic sand, after a heavy fraction separation by solvent extraction. In this study the hydrochlo
