Iron-storing bacteria may be used to mine gold, copper

MINING.COM | Arash Komeili, a Bakar Fellow at the University of California – Berkeley, just discovered that some species of aquatic bacteria may help miners in finding new ways to extract metals for commercial value or environmental cleanup. 

In an article prepared by UC, Komeili explained that the bacteria that he is studying are capable of drawing in dissolved iron from their watery environment and storing it in specialized compartments called magnetosomes. Then, they use the structures’ magnetic properties to migrate down to low-oxygen zones, near the Earth’s magnetic field.
