The importance of rare earth elements as the basis in development new technologies or improvement used ones, made a necessity its recovery, besides that from raw materials, waste materials. In this Hydrometallurgy and derivative Solvometallurgy, play key role due to operational characteristics, which are emphasized with use ionic liquids. manuscript reviewed most recent advances (2023 2024 years) about liquids unit operations (leaching separation technologies) aimed recovery these valuable strategic metals. Moreover, comprehensive review chemicals advanced materials containing some is presented.
