Investigation of Phenomena in Uranium Mine Waters using Hydrogeochemical Modeling – a case study

One of the main aspects in the remediation of closed uranium mine sites is the treatment of mine water. In order to understand speciation and processes in uranium mine waters, hydrogeochemical modeling is carried out. The importance of modeling in mine water treatment is shown by the example of two case studies. The first deals with precipitation processes in a stripping column. In the second case uranium speciation of different mine waters is characterized. By means of modeling results, treatment technologies can be adjusted and improved.
