Microorganisms in the processes of underground leaching

Lyudmila Zaynitdinova, Svetlana Kukanova, Takhir Aripov


Microbial diversity in pumping-out solutions of uranium by underground leaching was studied. It was established that pumping-out solutions in pH 3.0 and higher intensifies and stimulates development of mixotrophic thionic bacteria. Supplying oxygen by pumping air into wells leads to intensification of uranium carryout, which is accompanied by considerable increase in growth of almost all studied groups of microorganisms, especially those related to thionic neutrophils and Pseudomonas genus bacteria. The increased activity of these groups of microorganism may lead to higher concentration of uranium in solution.
