What is biomining? | American Geosciences Institute

1 of 2. 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. Valuable metals are commonly bound up in solid minerals.

Harnessing the Power of Microbes for Mining in Space

Conventional mining methods relied on heavy machinery, fire, and human labor. However, scientists have learned to harness the natural power of microbes to help. This process, called biomining, is used on Earth as a more environmentally friendly and cost-efficient way of obtaining these necessary metals. The same process could make it …

Microbial Mining

Microbial Mining. This website is dedicated to the use of microbes in the mining of metals such as Iron, Copper and Uranium. In short, the main use of microbes in mining is in microbial leaching. This is the process whereby a microbe will reduce or oxidise an insoluble metal into a soluble form, which can then be extracted and used by us.
