Biomining

Biomining refers to processes that use organisms to extract metals from ores and other solid materials. The largest application currently being used is the treatment of mining waste containing iron, copper, zinc, and gold. It may also be useful in maximizing the yields of increasingly low grade ore deposits. Biomining has been proposed as a relatively…
