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 1.8 t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s. Figures 2.4(a) and (b) show typical wet and dry density and w profiles with depth for

tailings led to the passage of the Uranium Mill Tailings Radiation Control Act (UMTRCA). Pursuant to the regulations promulgated under UMTRCA (40 CFR 192), the Department of Energy (DOE) at Title I sites and NRC licensees at Title II sites have almost completed the restoration and stabilization of current tailings impoundments.

MP Materials has a tailings processing plant that generates a dry cake, which is stored at a lined impound to protect groundwater. The water reclaimed from the tailings is recycled back into the production process, greatly reducing the need to draw fresh water supplies from the surrounding aquifers.

Tailings

Tailings

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
