Fractionation study of didymium carbonate by liquid-liquid extraction

  • 1. Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, SP (Brazil)

Description

This paper describes the study of various parameters of the fractionation process of didymium carbonate into light/medium and heavy rare earths concentrates by solvent extraction. These products constitute intermediate materials in the overall process to obtain high purity rare earth oxides, by solvent extraction, fractional precipitation and ion exchange techniques, presently being developed at IPEN.
