Abstract
Strategic minerals and metals are needed for the clean energy transition for use in production of electric vehicles, wind turbines, solar panels, energy storage and more. Canonical mining practices are unable to keep pace with this demand, often resulting in significant liabilities including increased carbon emissions and expanding waste streams.This surge in demand, coupled with a pervasive shift toward mining lower-quality ore bodies, underscores the urgent need for innovative and sustainable approaches that enhance extraction efficiency from ore bodies and waste streams while minimizing long-term environmental impacts.
Microbes are an often-overlooked natural resource already hard at work on mine sites. These invisible yet powerful organisms help to manage and transform the environment around them. By harnessing their abilities, we can put microbes to work to make mining more efficient and environmentally friendly. In this presentation, we explore how DNA-based genetic tests can be used to find, extract, and manage resources. By testing the genetic profiles of microbes already on mine sites, we can harness their unique capabilities to address pressing operational challenges in the mining industry. This approach allows us to identify specific microbial functions that can be optimized for resource extraction, environmental monitoring, and remediation, ultimately facilitating more efficient and sustainable mining practices.
We examine real-world case studies that demonstrate how microbes can transform resource extraction practices while minimizing ecological impact throughout the mining lifecycle. Starting with the early prospecting stages, we show how shovel-deep soil-resident microbes reveal buried resources, helping pinpoint valuable drilling targets, de-risking operations and reducing unnecessary ecosystem impact. During the extraction phase, we explore advances in bioleaching—a process microbes currently use to produce 20% of the world’s copper—and highlight how we can expand this technique to re-mine waste, recovering copper, cobalt, nickel, and rare earth metals from tailings with minimal environmental footprint. In the often-challenging tailings environment, we illustrate how microbes can stabilize these byproducts, reducing dust and increasing material strength for safer tailings facilities. Beyond extraction, microbes are essential for timely environmental monitoring and remediation; they react quickly to changes in their surroundings, acting as natural indicators of ecosystem health analogous to point-of-care diagnostics in human health and disease.
This approach to “microbial mining” addresses current environmental challenges and supports the global shift to greener energy technologies. By unlocking the hidden power of microbes, we pave the way for an efficient, responsible, and resilient mining future that aligns with global sustainability goals.
