Biomining: metal recovery from ores with microorganisms

Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

It looks like microbes can help clean up mining pollution

2018-8-23 · The abandoned mine has a poisonous legacy that stretches back 4,000 years – heavy metals have been extracted here since the early Bronze Age. Once the largest copper mine in the world, the site in North Wales stopped producing in the 1950s because it became cheaper to import copper ore from other countries.

New project promotes using microbes in mining

2022-2-2 · Many microbes and genes have evolved “little tricks” to process metals, extract metals, or leave others behind. The goal, he said, is to create a library of these microbes and genes and use that data in collaboration with other companies to develop new technologies and make them profitable. Using microbes is nothing new to the mining industry.
