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, 4 g/l ferrous ion and - 106µm particle size.   UR - https://ijcce.ac.ir/article_6092.html L1 - https://ijcce.ac.ir/article_6092_9d3306a5a43840d18b6618c08cc9f5a3.pdf ER -
