| Abstract | Experimental data on the mobility of uranium in hydrothermal fluids are required to accurately model the formation of uranium ore deposits. This study aims to conduct experiments on the solubility and
speciation of U(IV) and U(VI) in fluoride- and phosphate-bearing solutions, as well as flow-through, fluid-rock interaction experiments designed to assess the optimal P-T-X conditions for U precipitation, which will be integrated into a comprehensive
genetic model. Early work has focused on method development for the solubility and flow-through experiments. Preliminary experiments on UO2 solubility in 0.01 M F- solutions at 200°C produced concentrations of 1.76 to 3.92 ppm U, demonstrating the
surprisingly high mobility of U(IV) and the importance of U fluoride complexes for ore-forming systems. |
