| Abstract Scope |
The redemption of Rare Earth Elements from coal ash has multifarious advantages in utilization of waste and also as a way to minimize unnecessary mining. There is a significant escalation in the quantity of coal ash production, as well as the need of REE in modern day advanced technological products. Utilization of coal ash, knowing its REE enrichment, has been a persistent area of research and development.
Our approach is to extract REEs from coal ash in a non-destructive way utilizing least quantity of relatively eco-friendly lixiviant. The novelty lies in efficient and selective leaching of REE using milder and less corrosive reagents compared to mineral acids. Our research group is currently engaged in exploring the leaching potential and kinetics of novel organic lixiviants which can leach REEs (~60-70%) using lower quantities (2-10%), preferably in a single step. Interesting findings from our experimental work will be discussed. |
