Uranium Transport in F-Cl-Bearing Fluids and Hydrothermal Upgrading of U-Cu Ores in IOCG Deposits

<div>Uranium solubility in 0.51 molal NaCl solutions in equilibrium with metaschoepite or Na<sub>2</sub>U<sub>2</sub>O<sub>7</sub>·H<sub>2</sub>O(cr) at 298.15 K plotted as a function of pH. (a) Uranium solubility calculated with the thermodynamic model used in this study, compared to the solubility data of Altmaier et al. [<a href="/journals/geofluids/2018/6835346/#B77">77</a>]. (b) Distribution of species for the simulation in (a); predominant species are highlighted.</div>
