Can bacteria help us mine waste? – The Anthropic Times

26/04/2019  Bacteria can help us. Bioleaching is a process used in mining to extract metals using bacteria adapted to live in extreme environments – with high concentrations of metals and very acidic (corrosive) or alkaline (bleach like) conditions. Bacteria feed on nutrients in the minerals, such as iron or sulphates, allowing the metal to separate from the rock. Living in extreme environments calls ...

It looks like microbes can help clean up mining pollution

23/08/2018  The idea with this system is that the bacteria catalyze a change in chemical/physical conditions. They increase the pH as they grow, which causes metals to fall out of solution abiotically. The major players also convert the speciation of the iron to make it easier to precipitate out. We are replacing an abiotic catalyst (e.g. carbonate) with one that is already present). You would need to ...

Biomining - Wikipedia

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.
