Radionuclide and heavy metal redistribution at the former pilot-scale apatite plant in Sokli, northern Finland
A new phosphate mine is being planned at Sokli in northern Finland. In the late 1970s, pilot-scale mining and mineral processing took place at the site. The mobilisation of radionuclides and heavy metals from the mill tailings was examined in order to assess the potential environmental impact of pas...
