Abstract
Uranium bearing hydrothermal solutions during the stage of ore deposition are weakly alkaline and of the Ca2+ - Na+ /HCO3− - F− type. UO2(CO3)22− and UO2F4−, are dominant in the hydrothermal solutions with respect to their activity. Wall-rock hydrothermal alterations, temperature and pressure drop and the reducing capability of rock assemblage (ΔEh) led to a decrease in Eh of the hydrothermal solutions and an increase in Eh at which uranium began precipitating. Therefore, the mechanism of uranium precipitation is essentially the reduction of uranium complexes.
