Recovery of Rare Earth Elements from Coal Fly Ash

My thesis research focuses on recovering rare earth elements from coal combustion residuals (fly ash and bottom ash) and other incineration solid wastes. Our current methods to extract rare earth elements from solids (ash or mineral) are energy and acid intensive, and their separation efficiency is low, meaning that even further processes are required to separate each of the elements from each other. I'm working on designing and optimizing new materials and methods to achieve more efficient and environmentally sustainable separation.
