What is REE and Y Extraction from Coal Ash about?

The study investigates the concentration, characterization, and optimized extraction of rare earth elements and yttrium (REE + Y) from coal ash at the Luzhou power plant in Sichuan, China. It finds that both fly ash and bottom ash are enriched in REE, with fly ash containing over 70% amorphous glass, which is crucial for extraction processes. An alkaline-acid-combined leaching method was optimized, achieving high extraction efficiencies of REY from the fly ash, suggesting coal ash as a viable alternative re
