- Аннотация: New data on the solubility of tantalum oxide in mixed fluids (HF + HCl) at T = 550 oС and Р = 100 MPa in the presence of the oxygen buffer Co-CoO are obtained. The initial HF concentration varied from 0.01m to 2m, and HCl concentration remained constant and was 0.5 m. The limiting contents of tantalum in hydrothermal fluids of different composition are determined and the comparative characteristics of Ta's behavior depending on the concentration and composition of the solution are obtained. It is established that in the region of low initial concentrations of solutions (0.01 m HF + 0.5 m HCl) the equilibrium concentration of Ta is only 10-6 mol / kg H2O, and in the region of high fluid concentrations (2 m HF + 0.5 m HCl) it increases to 10-2 mol / kg H2O,
