Abstract

One of the main challenges in Uranium Bioleaching process is events related to improvement, acceleration and enhancement of the extraction. One of them is to provide a favorable environment and biological conditions for Acidithiobacillus Ferrooxidans. While, the nutrients of bacteria medium have a significant impact on the activity and growth of bacteria, in the present study, two selective culture mediums were used in Uranium Bioleaching process at pulp densities of 2. 5 and 12. 5 %. The media are containing the usual 9k and enriched 9k medium with Peptone and TSB (Tryptic Soy Broth). The Uranium Bioleaching process using the selective 2 media with different pulp densities were performed under optimum conditions. The results indicated that the Uranium extraction at 2. 5% pulp density, using the 9k-New medium and 9k medium, have carried out during 2 and 3 days, respectively. In addition, at 12. 5 % pulp density, the total Uranium in the ore was extracted during 3 and 7 days using the 9k-New and 9k media, respectively. Eh variations showed that the Eh in the 9k-New medium in compared with the 9k medium were increased 13-22%. According to the results obtained in this study, it is concluded that the use of nutrients such as Peptone and TSB have significant impacts on the activity of bacteria and also the speed of Uranium extraction. Thus, the optimization of the 9k medium using Peptone and TSB is recommended for the Uranium Bioleaching process.
