Polyethylenimine-modified chitosan materials for the recovery of La(III) from leachates of bauxite residue
The separation and recovery of rare earth elements (REEs) from leachates of bauxite residue has attracted increasing attention. Yet, the characteristics of bauxite residue leachates (low pH, low concentration of REEs, and ...
Electrochemical leaching of rare-earth elements from spent NdFeB magnets
Spent NdFeB magnets are highly appealing secondary resources for rare earth elements (REEs), especially for Nd. The goal of this study was to investigate electrochemical leaching of Fe and rare earths from NdFeB magnets ...
