On 18 June 2026, Elemental was delighted to host Professor Elizabeth Watkin at the Natural History Museum, London, for an insightful lecture on the role of microbial biotechnology in transforming biomining processes. The event brought together professionals, researchers, and students both in person and online to explore innovative approaches to sustainable resource recovery.
Professor Watkin presented two significant developments that demonstrate how microorganisms can help address some of the mining industry’s most pressing environmental and operational challenges.
The first part of the lecture focused on overcoming freshwater limitations in large-scale bioleaching operations. Professor Watkin highlighted the potential of halotolerant, acidophilic microorganisms, including members of the Acidihalobacter genus, to facilitate metal recovery in saline environments. This research offers promising solutions for mining operations in water-scarce regions, where access to freshwater resources can constrain production and increase environmental pressures.
The second theme explored the microbial recovery of rare earth elements. Professor Watkin discussed how phosphate-solubilising microorganisms can be used to mobilise and recover critical minerals, providing a potentially more sustainable and cost-effective alternative to conventional extraction methods. As demand for rare earth elements continues to grow, particularly in renewable energy and advanced technology applications, such approaches may play an increasingly important role in securing future supply chains.
The lecture stimulated engaging discussion among attendees, highlighting the growing importance of biotechnology in supporting a more sustainable and resilient mining sector.
Elemental extends its sincere thanks to Professor Watkin for sharing her expertise and latest research, and to all those who attended and contributed to the discussion.
We look forward to continuing these important conversations through future Elemental events.
