Radioactive Waste From Uranium Mining and Milling | US EPA

Regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.

Tailing Disposal an overview | ScienceDirect Topics

After settling and selfweight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to t/m 3 due to their higher G s. Figures (a) and (b) show typical wet and dry density and w profiles with depth for ...
