Review on the Processes for the Recovery of Rare Earth Metals (REMs) from Secondary Resources

  • Conference paper
  • First Online:

Part of the book series: The Minerals, Metals & Materials Series ((MMMS))

Abstract

Treatment of secondary/waste to recover rare earth metals (REMs) is gaining importance due to its increasing global demand, lack of availability of high grade natural resources and huge generation of secondaries. Present paper reports the critical review on available processes for recovery of REMs from secondaries viz. manufacturing scraps, e-waste , industrial residues such as red mud , fly ash, waste water , etc. Hydrometallurgical processes with combination of Beneficiation/Pyro-/Electro techniques are discussed to recover REMs effectively. The recommended processes require less energy to deliver high purity yield which is one step towards green environment. Salient findings on various methods are reported with recommendations which will be helpful to researchers working in the area of REMs extraction.
