of bacteria in mining

Aug 27, 2020· In 1922RudolfsandHelbronner, andWaksmanandJoffe, studied bacteria that could create sulphuric acid by oxidising sulphur compounds. Carpenter and Herndon did further work on the topic in 1933. In 1947 Colmer and Hinkle 'found' Acidithiobacillus (originally Thiobacillus) ferrooxidans in coalmine water, the first bioleaching microorganism to be officially identified.

    Although bacterial oxidation of sulfide materials results in the undesirable formation of acid mine drainage, the same reaction has been put to use for microbial leaching ofcopper,uranium, and other valuable metals from low-grade sulfide-containing ores. These metals are released from the ore after their conversion to more soluble forms by the direct oxidation of the metal by the bacterium and by the …
