Tailings dewatering Weir Group

Nov 18, 2019· As many mine sites need to be rehabilitated and restored to a natural state, a key benefit of producing thickened tailings is its ability to be covered with overburden and re-planted with suitable vegetation. How Weir Minerals can help. We realise that dewatering tailings can be a daunting process for many operators.

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

Dewatering Methods for Dewatering Excavation at

Dewatering during excavations is required at construction sites generally for foundation works. Dewatering of any excavated area is done in order to keep the excavation bottom dry so that excess water does not weaken the concrete or wash away cement. The excavation or laying foundation in the waterlogged ground is a very tough activity.

paste backfill Archives International Mining

Dewatering involves removing liquid from waste slurry so that the remaining solids can be deposited in a tailings storage facility or returned to the site from which it was mined as backfill. There are several dewatering methods to render waste slurry to differing degrees of dryness, ready for transport from the plant to the deposition site.

Paste Backfill Solutions CEC Mining Systems

By providing passive support for underground mining operations, companies can extract a greater proportion of the mine resource. By combining this customer value with minimizing the footprint of the mine’s tailings and increasing safety and stability of the underground workings, backfill is a competitive and valuable option in many scenarios.
