چکیده
|
This study deals with bioleaching of the low grade uranium ore of saghand mine in iran using a mixed culture of mesophilic bacteria (acidithiobacillus ferrooxidans, acidithiobacillus thiooxidans and leptospirillum ferrooxidans). experiments were carried out in shaking flask examining the effect of temperature, initial ferrous ion concentration, pulp density and particle size.variations of ph, eh, ferrous ion concentration, cells growth and uranium extraction were monitored. the highest rates of leaching and extraction were obtained at 35oc, 2.5% (w/v) pulp density, 4g/l ferrous ion and -106mm particle size
