Use Of Microorganisms In Mining

Mining With Microbes - CEN

Harnessing microbes to do mining work is called biomining, or sometimes bioextraction or bioleaching. The strategy has been most extensively studied for copper and gold: Colorado-based mining consultant Corale L. Brierley estimates that 10 to 15% of copper and 5% of gold worldwide are currently being harvested through biomining.
