Evaluation of coal-associated sediments, wastes, and AMD sludge in the Southern Appalachian Basin as feedstock materials for REE and Li recovery

Key Points

• Significant potential for rare earth elements and lithium recovery identified in coal-associated sediments.
• Coal-associated sediments may yield up to 12 grams of lithium per ton, indicating a viable resource.
• Analysis of journal articles and mining reports shows a growing interest in alternative resource recovery techniques.
• Findings support the need for further exploration of coal waste as a source of critical minerals.
