The advantages of this type of mining do not disrupt the environment and reduces air and water pollution related with smelting ores and the use of hazardous chemicals. On the downside, this type of processing is slow. It could take decades using bio mining to extract those materials that could be removed in months or years.
Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals.
