Reprocessing of Mining Tailings with Ellicott 370 Dragon

Sep 11, 2014· Tailings require fewer resources when compared to conventional mining. For example, a dredge can in a single step extract and transport the material to a processing plant located elven kilometers away. This reduces costs related to capital equipment, labor, fuel, and maintenance. Advances in re-processing technology

Tailings Wikipedia

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.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

Tailing Disposal an overview ScienceDirect Topics

After settling and self-weight 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
