What is Biomining? (with pictures) - wiseGEEKRepresented by microbial leaching and oxidation processes, biological mineral extraction has many potential areas of application but is, at present, mainly utilized to process gold and copper. The bioleaching process, one of the two refinement techniques, is a classic example of the simplicity of biomining methods.microbial mining of gold wise geek,What is Bioleaching? (with pictures) - wiseGEEKBioleaching is the use of bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. As an alternative to smelting or roasting, . improve their national economies. Many scientists believe that bioleaching might someday be used to mine metals such as zinc and nickel on the moon.

The secrets of microbial gold mining uncovered - Geek

Feb 14, 2013 . Perhaps you've heard of the mythological Greek king Midas, whose touch could turn any object into solid gold. If there was a microbial equivalent, it would be a bacterium called Delftia acidovorans. This little guy is one of a class of organisms called metallphores that are able to pull gold atoms out of.

This situation may change if a method to recover metals such as copper and gold in printed circuit boards—the greenish glass fiber boards present in most electronic devices—can be made sustainable in both the economic and environmental sense. The technique, known as bio-hydrometallurgy, was developed by a group.

Oct 24, 2014 . And just like conventional mining, it still requires digging up rocks and blasting them to bits. The difference is that rather than using heat to then extract the metals from these rocks, biomining uses microbes. Up to now, biomining has mainly been used to extract copper and gold from rocks where they're.

Oct 15, 2012 . Harnessing microbes to do mining work is called biomining, or sometimes bioextraction or bioleaching. The strategy has been most extensively studied for copper and gold: Colorado-based mining consultant Corale L. Brierley estimates that 10 to 15% of copper and 5% of gold worldwide are currently.

Heavy Metal Mining Using Microbes | Annual Review of Microbiology

Abstract The use of acidiphilic, chemolithotrophic iron- and sulfur-oxidizing microbes in processes to recover metals from certain types of copper, uranium, and gold-bearing minerals or mineral concentrates is now well established. During these processes insoluble metal sulfides are oxidized to soluble metal sulfates.
