Mining With Microbes Chemical & Engineering News
Harnessing microbes to do mining work is called biomining, or sometimes bioextraction or bioleaching. The strategy has “The microbes utilize a unique biological pathway with an array of proteins that can extract copper (II) (Cu 2+) and convert it into single-atom zero-valent copper (Cu 0).

What is biomining? American Geosciences Institute
Microbes are especially good at oxidizing sulfidic minerals, converting metals like iron and copper into forms that can dissolve more easily. Other metals, like gold, are not directly dissolved by this microbial process, but Copper is often found in a mix of metals, and microbes can help extract it by eating away at other materials in the ore. By giving these microbes free rein of mounds of materials left by mining A treasure hunt for microbes in Chile’s Atacama desert

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.Introduction. Currently, the world is plagued with the issue of enormous waste generation from various anthropogenic sources including mining and industrial activities (Ghosh and Das Citation 2020 a; Mishra et al. Citation 2021a; Singh et al. Citation 2020).These pollutants have emerged as potential threats to not only the ecosystem but Full article: Role of Microorganisms in Extenuation of Mining and

With deep-sea mining, do microbes stand a chance?
Land-based mining, which presents its own problems, yields 19 million tons of copper and 12 million tons of zinc annually. While the minerals in these deep-sea ecosystems may hold material, metallic value for people, focusing on what is bright and shiny might cause would-be miners and stakeholders to discard other treasures the deep OSTI.GOV.

Biological treatment for the recovery of minerals from low-grade
Especially, ancient Roman civilizations had a high demand for metals such as lead, zinc, copper, tin, mercury, etc. through mining for a high standard of living [1]. These miners used the microbial community to leach metals without having knowledge of a fact that microbes were associated with the process.12.7.2 Interaction of Microorganism in Copper-Bearing Mining Soil.

Wiley Online Library The Microbiology of Metal Mine
1 Introduction. Mine wastes are the unwanted by-products left behind after the ores of economic interest have been extracted, and can be solid, liquid or gaseous (Lottermoser, 2010).Mining has occurred for Closing the loop. A team of CSIRO and Murdoch University researchers recently reviewed global trends in materials recovery from e-waste and identified opportunities and barriers to establishing new industries in Australia and New Zealand. They noted the value of recoverable materials in the world’s e-waste stockpile is an estimated US$60 billion.Microbes to mine metals from e-waste? CSIRO

Arsenic-transforming microbes and their role in biomining
The previous section examined the potential use of microbes in mining. In this context, the frequent occurrence of arsenic as an impurity in many metal-rich sulfide deposits is problematic. The presence of arsenic in mineral concentrates drastically decreases their economic value and can cause a number of difficulties associated with In Chile, copper mining has contaminated the soil with several metals, including zinc, lead, cadmium, and arsenic, but our previous studies of actual mining-contaminated soils have shown that copper is the only metal that is toxic to plants (Mondaca et al., 2017; Verdejo et al., 2015, 2016) and earthworms (Delgadillo et al., 2017), while Microbial responses are unreliable indicators of copper ecotoxicity
