Biomining, or bioleaching, represents a revolutionary approach to metal extraction using microscopic bacteria like Acidithiobacillus ferrooxidans that can oxidize minerals and release valuable metals from ore. This technique harnesses natural bacterial metabolic pathways to extract metals from low-grade ores that would be economically unfeasible through conventional methods. Recent advancements have improved extraction efficiency by 37%, with approximately 15% of the world's copper extracted using bioleaching. The process offers significant environmental benefits, requiring less energy, fewer harsh chemicals, and producing lower carbon emissions, potentially reducing mining-related emissions by up to 30%. Additionally, biomining can remediate mine tailings while recovering valuable metals, transforming environmental liabilities into economic opportunities. The technology is particularly promising for developing nations, requiring less initial capital investment and creating opportunities for community-based initiatives. Despite challenges like slower extraction times and temperature sensitivity, ongoing research includes developing genetically modified bacterial strains and exploring applications for extraterrestrial resource extraction.
