Mining With Microbes Chemical & Engineering News

2012-10-15 · 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.

Microbial communities in rare earth mining soil after

2021-2-10 · In this investigation, 12 mining soil samples were collected in a rare earth mining area where in-situ leaching practice had been used to extract REEs. The community structures of bacteria, archaea, and ammonia-oxidizing microorganisms were analyzed to elucidate the impacts of in-situ leaching mining on soil physicochemical properties and microbial communities.

Heavy Metal Mining Using Microbes Annual Review

2019-7-17 · Abstract The use of acidiphilic, chemolithotrophic iron- and sulfur-oxidizing microbes in processes to recover metals from certain types of copper, uranium, and gold-bearing minerals or mineral concentrates is now well established. During these processes insoluble metal sulfides are oxidized to soluble metal sulfates. Mineral decomposition is believed to be mostly due to chemical attack by
