Abstract:

The thermodynamic model of uranium in situ leaching process at the stage of acidification was investigated. It was demonstrated that in the frontal zone of acid leaching solutions reduction of U(VI) up to U(IV) was possible due to the behavior of oxidation-reduction processes with the ferrous ions involved. At the same time uranium is precipitated as U(OH)(4). In order to eliminate the negative influence of ferrous iron ions, artificial oxidizers were proposed to be used not only at the stage of active leaching of cells but also at acidification stage of new process cells.
