Electrorefining in Sustainable Metals Production

Electrorefining has historically played a crucial role in the production of high-purity metals, evolving since the 19th century when applications for copper, gold, and silver emerged. This editorial discusses the significance of electrorefining within the context of sustainable metal production, emphasizing its advantages over traditional pyrometallurgical methods, particularly in achieving higher purity levels. The methodology described involves the use of electrochemical processes to produce metals such as cobalt, copper, gold, and silver, which are key to meeting both industrial and environmental sustainability goals. By examining the practices and innovations in electrorefining, the article highlights potential improvements, particularly related to circular economy principles and the recycling of metal-containing wastes, which are critical as global industries evolve towards sustainability. Insights from existing research suggest that advancements in electrolyte systems and process parameters can enhance efficiency and reduce environmental impact. This work aims to inspire further research directed at integrating sustainable practices within metallurgical engineering, supporting the broader objectives set by the Sustainability Development Goals 9 and 12. The potential for electrorefining to meet future demands for high-purity metals sustainably points towards its continued relevance and necessity in the 21st century.
