Mining and Microbiology - Bangor University

Mineral processing using microorganisms has been exploited for extracting gold, copper, uranium and cobalt, and new operationss are targeting other base metals. Engineering systems ranging from crude heap leaching systems to temperature-controlled bioreactors have been used, depending on the nature of the ore and the value of the metal product.

Biomining - Wikipedia

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
