Copper Mining Using Acidothiobacillus - microbewiki23/7/2011· In 2009, global copper consumption topped 21 billion tons (Copper Development Association), and that kind of demand has led to the development of sophisticated mining techniques. Copper is rarely found in its native form; most often it exists as ores made up of various copper sulfides and oxides that have little practical value of their own (Australian Atlas of Minerals, Resources, and ...Biomining and bacteria - Down to EarthFor one, their mining methods are not offensive to the environment as are most other techniques, which use explosives, toxic chemicals and high temperatures (Science, Vol 264, No 5160). Biomining, as it is called, also makes for better economics, especially in extracting minerals from low-grade ores, which are being used increasingly because of depleting high-grade reserves.
