Thorium Nuclide Extraction and Quantitative Measurements in Minerals

The extraction characteristics of Thorium nuclide play a decisive role in Thorium migration in groundwater and soil. This paper takes a set of Thorium extraction experiments for some tailings dam according to the Thorium content in tailings. These experiments are to achieve the lixiviation characters of Thorium under different conditions so as to ensure the accuracy of Thorium migration in groundwater and soil parameters set. Experiments results denote that neutral conditions make the Thorium migration weak while acidic conditions enhance the speed of migration in groundwater and soil. Therefore, acidic wastewater should not directly discharge into the tailings, or migration of thorium will be greatly enhanced.
