Germanium, a critical material for advanced technologies, is enriched in certain coal deposits and by-products, including combustion gasification fly ashes. This review examines germanium concentrations occurrence modes coal, gangue, their or as well hydrometallurgical recovery methods at laboratory, pilot, industrial scales. Fly ashes from both are particularly promising due to higher content rates, which can exceed 90% under optimal conditions. However, the low high levels of impurities leachates pose challenges, necessitating development innovative selective separation techniques, primarily involving solvent extraction, ion exchange, adsorption.
