Advances in Biotechnology
At one of the Kazakh uranium deposits, studies were carried out on the effect of ironoxidizing bacteria on the redox potential of leaching solutions. The studies carried out on three bioreactors with a volume of 1 m3 and one bioreactor with volume 6 m3 made it possible to establish a close relationship between the content of ferric iron in the solution and the redox potential of the leaching solution. In situ recovery of uranium uses sulfuric acid leaching solutions containing sulfuric acid from 3.5 g/liter to 25 grams/liter. Diagrams of the relationship between redox and the content of a trivalent iron in solution were obtained. This makes it possible to carry out an operational analysis of the composition of the leaching solution according to the redox of the solution directly in the conditions of the geotechnological field.
