As one of the globally strategic critical metals, rhenium often exists in copper ores in an associated form. Copper smelting waste acid, an important carrier of rhenium resources, exhibits complex characteristics including high acidity, high impurity content, and low rhenium concentration. The characteristics pose formidable challenges to the rhenium recovery process. The key technologies for rhenium recovery from waste acid, with a particular emphasis on the progress of advanced purification technologies targeting the leaching solution are systematically summarized. The working principles, process optimization approaches, and industrial application effectiveness of solvent extraction and ion exchange methods are analyzed in depth. Moreover, the differentiated technical routes for leaching solution purification employed by major copper smelting enterprises worldwide are compared. Based on this, the key technical bottlenecks and potential breakthroughs for future development in this field are explored from multiple perspectives, including innovation of separation materials, process intensification, process integration, and secondary pollution control. The aim is to offer in-depth theoretical references and practical guidelines for the efficient, environmentally friendly, and high-value recovery of rhenium resources from waste acid.
