Ion exchange is an essential technique in hydrometallurgical operations for recovering and purifying valuable metals, particularly in the copper-cobalt sector. This study examines the applications of ion exchange, specifically focusing on chelating and solvent-impregnated resins, to achieve improved metal purity and economic efficiency. Through the selective removal of impurities from cobalt-rich liquors, including metals such as iron and uranium, the research highlights the increasing importance of these methods in the context of depleting high-grade ores and the growing demand for high-purity materials, driven largely by electric vehicle production. The paper outlines the mechanisms of ion exchange, emphasizing the superior selectivity of special chelating resins for target elements. It also discusses the environmental benefits of using ion-exchange resins in processing tailings, which not only recovers additional valuable metals but also enhances the environmental and social governance credentials of mining operations. Overall, the findings illustrate the critical role of ion exchange in meeting the challenges of modern metal production, particularly under conditions of increasing impurity levels in lower-grade ores.
