Radioactive and other environmental contamination

2015-1-1  Mill tailings are the residual slurries from the wet processing and are the main wastes from conventional ore milling. They contain, inter alia, the nuclides 230 Th and 226 Ra, which are typically not removed by the milling process (IAEA, 2004b). They are disposed of in tailings management facilities that may also receive other waste streams, such as neutralization slurries.
