Functional comparison of Acidithiobacillus ferrooxidans in uranium recovery from Saghand mine (anomaly I and II)

The study aim is functional comparison of native Acidithiobacillus ferrooxidans in uranium extraction from two types of Iranian ore. For this purpose, the bacterium cultivated in 9k medium with pH 2 and 5% pulp density of anomaly I and II of Saghand mine. In following, the flasks incubated at 150rpm and 35oC. Sampling carried out every 24 hr for measurement of uranium extraction. The results showed that, the native Acidithiobacillus ferrooxidans is capable of uranium extraction (100%) from anomaly I and II during 2 and 3 days, respectively. Meanwhile, the ability of the bacterium in uranium extraction from two types of ores was different.
