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.

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

Outotec® Modular Paste Backfill 80 PLANT Outotec

Underground non-ferrous mines that use paste backfill require a backfill system to provide structural support throughout the life of the mine. Mine backfill also minimize s the volume of tailings that need to be directed to tailings dams on the surface. A high-quality backfill system is vital to ensure mine integrity and the safety of personnel.
