Many mining operations produce tailings that dewater very slowly under self-weight consolidation. One way of reducing the water content of such tailings is by electroosmotic dewatering.
Mine tails dewatering - How to extract more water ...
RE: Mine tails dewatering - How to extract more water?? Kivi (Mining) 11 Jul 05 13:11 This is a big question, and as PBroad mentioned, transport distances also play a part as using higher densities of slurry requires positive displacement pumping which is more expensive, but lower cost to run/per solids througput.

Tailings - Wikipedia
Terminology. Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon).. Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS 2) and Iron(II) sulfide (FeS ...

Dewatering Techniques for Construction Projects
Dewatering can also refer to the process of removing water from the soil by wet classification. Wet classification is a construction process that looks at the size of particles that make up the underlying soil in a project site and the flow of fluids through those particles.
How to Make Filtered Tailings Feasible | E & MJ
And you're only going to dewater, say, 20% or 30% of the tailings, that does a lot for the mine. That allows them more time to find a longer-term solution if they think the mine life will be extended. "It allows them to de-risk a higher performance dewatering tailing solution.
How a Thickener Works - 911metallurgist.com
How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...

Dewatering Cyclones | Multotec
Small diameter dewatering cyclones: For slurry dewatering or water recovery (i.e. high solids yield to the underflow), we recommend our range of small diameter dewatering cyclones that achieve a fine cut-point. A higher-feed pressure can also be accommodated in small diameter dewatering cyclones, which assists in achieving a fine cut-point.
Dewatering Management at Mine Sites | Pumps & Systems
Dewatering is an essential process of removing water from a location—virtually every mine site needs to account for dewatering at some point in time. Most mine operations are susceptible to flooding—some more than others. The geographic location and climate of the area play a major factor in dewatering needs. Heavy rainfall, water tables, nearby rivers and lakes can lead to catastrophic ...
Mine Dewatering (NT) - DunnHydroGeo.com
Mine Dewatering Results. This quick analysis using AEM suggests that two dewatering wells pumping (or siphoning) a total of about 120 gpm might eliminate 84 gpm of acid mine water discharging to the stream from the tunnels. The only water entering the tunnels might be seepage from the unsaturated rock above the water table.
