Overview

The Selective Recovery of Rare Earth Elements from Spent Permanent Magnet Leachates using Diglycolamide-phosphoric acid Impregnated Resins (Id 490)
Master theses
Rare earth elements (REEs) are vital to numerous industrial applications.
The studies on REEs recovery from various secondary resources revealed that spent permanent magnets contain a significant amount (approximately 31-32 wt%) of rare earth metals.
To address this, an extraction chromatography method has been proposed for the selective recovery of REE from leachate solutions.
The master’s thesis aims to develop novel diglycolamide-phosphoric acid combined impregnated resins with different compositions for the selective recovery of the REE from the spent magnet leachates.
The prepared impregnated resins will be optimised with different experimental parameters to assess the best possible recovery of REEs.
The studies will be examined through spectroscopic and analytical investigations to understand the insights into the extraction/sorption behaviour.
The application to real magnet leachates would be tested.

Conduct literature research on extraction chromatography on resins, impregnation with various ligands, and their applications in metal recovery
Design and conduct laboratory experiments under several parameters such as contact time, acid concentration, sorption models, etc.
Optimize experimental conditions for recovery of REE from magnet leachates
Prepare a thesis report and present findings at conferences or workshops

Bachelor’s degree in Chemistry, Chemical Engineering, Environmental Engineering, or related field
Knowledge of ion or extraction chromatography, and impregnation of inert carrier resins
Knowledge of analytical techniques such as FTIR, SEM, AFM, XRD, etc.
