Innovative metal recovery technique: turning low-concentration solutions into valuable resources
A recent review article discusses a novel method called electrodeposition-redox replacement (EDRR) for efficiently recovering precious metals from industrial solutions. The increasing demand for metals and the depletion of high-grade raw materials make efficient metal extraction crucial. EDRR combines electrodeposition and redox replacement processes to recover metals like silver, gold, platinum, and tellurium from their low concentration solutions. The technique is highly controllable and does not require additional chemicals. EDRR has been successfully applied in lab settings for metal recovery and material functionalization, allowing for the creation of various metal products and surfaces with desirable properties. With the potential for optimizing energy consumption, enhancing circular sustainability, and developing versatile functional materials, EDRR will further contribute to sustainable metal production and materials science.
The review article was published in Chemical Engineering Journal, Volume 465 (Linfan Cui, Kirsi Yliniemi, Jaana Vapaavuori, Mari Lundström).
