Toxic Mines: Benefits of Bioleaching Bacteria

We predominantly use tanks for our projects, where the bacteria oxidise the sulphides within optimal operating and living conditions. At the beginning we use five or six but by the time we get to the end we have two settling tanks. One tank has a pregnant solution of base metals such as zinc, copper, nickel. The bacteria create a sulphuric acid in the tank by oxidising the sulphides. When that ...

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.
