Abstract
Natural and technogenic sources of rare earth elements (REE ) and other rare and scattered metals are remarkable for their chemical diversity. The pregnant solutions going to processing for the valuable metals have very complex compositions. Both targeted elements and competing impurities are present in the solutions in different chemical forms. Thus processing of such materials demands application of different technological tools addressing numerous specific tasks on the way to the final product. Screening work was undertaken to identify the best resins among developmental and commercial products addressing typical cases in the hydrometallurgy of scandium and REE . The cases outline typical sources of scandium and REE , such as streams of TiO2 production, extracted phosphoric acid, barren uranium solutions and others. Specially designed ion exchange resins can be effective tools.
