  • Do humans use bacteria to mine minerals from the ground ...

    2022-1-23 · Do humans use bacteria to mine minerals? Microbes currently are used in mining to help recover metals such as gold, copper and uranium. Now researchers suggest bacteria could be enlisted for “bio-mining” in space, to extract oxygen, nutrients and minerals from extraterrestrial bodies such as the moon and Mars for use by future colonists there.

    limitation in the use of reactors in biomining is the very large amounts of run-of-mine ore that in most cases is to be treated. The Chuquicamata copper mine in Chile produced 630,000 tons of fine copper in 1999. The production of that amount of metal implied the treatment of around 6 million tons of run-of-mine. If
