Electrochemical Rare Earth Recovery from Coal Fly Ash: Turn Waste Stockpiles into Critical Materials Revenue Technology Overview Researchers at Idaho National Laboratory have developed an electrochemical process that selectively extracts rare earth elements (REEs) from coal fly ash leachate using electricity instead of chemical reagents. The technology employs tuned anodic electrosorption with functionalized mesoporous carbon electrodes to achieve superior separation of REEs from competing metal ions. Opportunity Coal fly ash represents a massive, untapped resource: 158 million tons produced annually in the U.S. 1.5 billion tons currently stockpiled Contains 74,000-106,000 metric tons of rare earth elements Current extraction methods don't work at scale. Traditional solvent extraction reli
