The most important group of bacteria which are involved in sulfide minerals leaching are the acidophilic Thiobacilli which belongs to the family Thiobacteriacrae. They have the ability to use the oxidation of inorganic sulfur and its compounds to produce energy for growth.

Bacteria Found to Thrive on Gold. A species of bacterium forms nanoscale gold nuggets to help it to grow in toxic solutions of the precious metal, reports a paper published online today in Nature Chemical Biology. The molecule with which the bacteria create the particles could one day be used to collect gold from mine waste, says Frank Reith,...

Abstract. The alkyne is an important functionality widely used in material science, pharmaceutical science, and chemical biology, but the importance of this functionality is contrasted by the very limited number of enzymes known to be involved in alkyne biosynthesis. We recently reported the first known carrier proteindependent pathway...

Microbes such as bacteria and fungi convert metal compounds into their watersoluble forms and are biocatalysts of these leaching processes. Additionally, apply ing microbiological solubilization processes, it is possible to recover metal values from in dustrial wastes which can .

Gold extraction. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of lowgrade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores .

Bacterial colonies perform a cooperative and distributed exploration of the environmental resources by using their quorumsensing mechanisms. This paper describes how bacterial colony networks and their skills to explore resources can be used as tools for mining association rules in static and stream data.

known species of bacteria not directly related with soil or water surrounding mining activities (Dash et al., 2008; Ezzi and Lynch, 2005; Gurbuz et al., 2009). Though officially prohibited, the use of cyanide in artisanal small scale gold mining (ASGM) is widespread in WestAfrica, particularly in Burkina Faso (Butaré and Keita, 2009).

Bacteria Do the Job. These bacteria live in the uraniumrich strata and use uranium as an electron acceptor in their natural life cycles. A number of substances, such as safflower, crude whey protein and even molasses, have been used to "feed" the bacteria, but the results were mixed.

"These bacteria are all acidophilic –, they like an acidic environment – and can oxidize metal sulfides," Schippers explains. Biomining is a metal extraction method that is based on the use of bacteria. "This technology now accounts for around 15 percent of all copper mining worldwide," says Schippers.

Some of those bacteria can liberate copper and nickel from the ore into a liquid form by breaking down the iron products in that ore, he said. Once the bacteria do their job, it's much easier to recover the liquid nickel and copper through a process called electroplating.
