Mine dewatering - Wikipedia

Mine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine workings. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require the use of very large …

Tailings - Wikipedia

Dewatering is an important part of pond storage, as the tailings are added to the storage facility the water is removed - usually by draining into decant tower structures. The water removed can thus be reused in the processing cycle. Once a storage facility is filled and completed, the surface can be covered with topsoil and revegetation commenced. However, unless a non-permeable capping method is …
