The Future of Mining: Using Microbes to Unlock Pure Copper

This episode of Primer investigates a revolutionary approach to mineral extraction that uses microbial communities and sulfuric acid to harvest copper from low-grade ore. By leveraging biological processes, this technology aims to unlock valuable resources from giant piles of rock that were previously dismissed as economically unviable using traditional mining methods. Despite the scientific promise of using bacteria for mineral processing, the transition from laboratory success to industrial scale remains a significant challenge. The report explores the technical hurdles that engineers face in scaling this microbial technology and why it is so difficult to implement across the global mining infrastructure.
