Kinetic enhanced separation of praseodymium and neodymium induced by specific ion effect

Na Sui et al.

Summary: Efficient separation of Pr3+/Nd3+ was achieved in this study by implementing a kinetic extraction strategy in systems with different salting-out agents. The experimental results showed that the separation coefficient can be higher than 8. The enhancing effect on separation of Pr3+/Nd3+ from different salting-out agents was related to the salting-out effect, which was influenced by the type and concentration of the agents.

Modelling and optimization of a new complexing retardant-enhanced polymer inclusion membrane system for highly selective separation of Zn2+ and Cu2+

Lelin Zeng et al.

Summary: This study proposes a method to enhance the selectivity of polymer inclusion membranes (PIMs) by adding a complexing retardant and establishes a mass transfer mathematical model to reveal the enhancement mechanism. Contrast experiments demonstrate that the complexing retardant significantly improves the overall separation coefficient. Further investigation identifies the optimal conditions for achieving the maximum separation effect. Lastly, optimization strategies for the retardant-enhanced PIM system are discussed based on simulated calculation.

Studies on effective interaction parameters in extraction of Pr and Nd using Aliquat 336 from NdFeB magnet-leaching solution: Multiple response optimizations by desirability function

Hesamoddin Gorzin et al.

Summary: Praseodymium (Pr) and neodymium (Nd) were extracted from NdFeB magnet-leaching solution using nitrate form of Aliquat 336. The study found effective inter-parameter interactions in the system under different operational conditions and performed two separate optimizations using the desirability method. Extraction efficiencies and separation factors were determined for each optimization, indicating distinct feedback and results under varying conditions.

Development of Hydrometallurgical Process for Recovery of Rare Earth Metals (Nd, Pr, and Dy) from Nd-Fe-B Magnets

Pankaj Kumar Choubey et al.

Summary: This study explores the recovery of rare earth metals from discarded magnets, with a process including demagnetization, pre-treatment, and hydrometallurgical processing. The results show successful recovery of Nd, Pr, and Dy, with solvent extraction achieving partial separation of REMs and Fe. However, the multistage separation required for this process may not be economically feasible.
