| Summary: | The effect of mineral particle size on the bioleaching of uranium from Saghand mine (anomaly 1&2) by acidophilic mesophile Acidithiobacillus ferrooxidans was investigated in a shake flask. The findings are indicating that this strain is suitable for the uranium recovery from the mentioned ore. In the range of our studies the uranium recovery is faster in the case of d80=108 micron from anomaly 1, while, a comminution level of d80=160 micron was obtained as an appropriate size for the anomaly 2. The results showed that the particle size distribution of the mineral in this range did not considerably influence the microbial activity. Also, based on the results of bacterial oxidation, the negative effects and toxicity due to the presence of solid and solute components do not put a limit on the microbial activity, and at the tested parameters range, the grown microbial population is performing the desired process excelently. |
