Thermodynamic Characterization of Dissolved Uranium Species in Flooded Uranium Mines and Tailing Management Facilities

摘要：

　　For the effective treatment of uranium-containing mine waters, an identification of predominant uranium species is of great interest.Therefore, species distributions are modeled with the hydrogeochemical software PhreeqC.Modeling results depend extensively on the used thermodynamic data.When considering calcium uranyl carbonates, one of them appears predominant at neutral pH values.However, this complex does not occur at low pH.These facts influence mine water treatment processes.
