Recovery of titanium from coal gangue is significant for both high-value utilization of solid waste and resource security. This review systematically examines the occurrence of titanium in coal gangue and its influence on enrichment and extraction processes. It focuses on the applicable conditions and technical bottlenecks of mainstream hydrometallurgical techniques, such as acid leaching, alkali fusion, and roasting-leaching. Comparisons are made with physical sorting and emerging green technologies, including bioleaching and ionic liquid extraction. Future research directions are also discussed, aiming to provide a reference for the economical, environmentally friendly, and efficient recovery of titanium resources from coal gangue.
