Water retention tailings dams are mainly used for mineral operations that plan to store high volumes of water. Water storage may be required to keep a processing plant operational during the dry season or where surface water inundation can occur especially if the impoundment is in a catchment area.

Seepage Control for Tailings Dams

The paper addresses the problem of seepage control for tailings dams. Conventional flow nets are presented to illustrate the effectiveness of various seepage control mea­ sures which are normally used in the design of water storage dams. The application of these measures to tailings dam de­ sign and construction is then discussed.

Tailings - Wikipedia

Subaqueous storage of tailings has also been used. Tailing ponds are areas of refused mining tailings where the waterborne refuse material is pumped into a pond to allow the sedimentation (meaning separation) of solids from the water. The pond is generally impounded with a dam, and known as tailings impoundments or tailings dams.

BHP | Tailings Dams Briefing Transcript

A key term to be familiar with when thinking of tailings dams is the notion of a tailings storage facility. This is the term commonly used to describe a cluster of individual tailings dams which are co-located or a single large dam. Currently there is no industry-wide agreed definition for this term.

What are tailings dams? | IndustriALL

Tailings dams are used to store water and waste that come as by products from the mining process. It is estimated there are at least 3,500 tailings dams around the world. But as there are around 30,000 industrial mines, the number of tailings dams is likely to be much higher. Tailings dams can be ...

PROPERTIES OF TAILINGS DAMS - WISE Uranium Project

The embankments forming these impoundments are earthfill dams. Although water-retention type dams would be very suitable for tailings dams, they are not used for their high cost. Other than water-retention type dams, tailings dams usually are not constructed initially to completion, but raised sequentially as the impoundment fills.

A review of the risks posed by the failure of tailings dams

Tailings dams are often constructed with readily available materials rather than the concrete used for example in water storage dams. Tailings dams also differ from water storage dams due to the fact that the construction phase of a tailings dam continues for the operating life of the mine processing plant, sometimes lasting several decades with

Tailing Disposal Methods and Tailings Dam Construction Design

Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.
