Tailings dam - Wikipedia
A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive.
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 huge in size, as big as lakes, and reach 300 metres high. As the slurry of waste is piped into the dam, the …
Tailing Dam - an overview | ScienceDirect Topics
In South Africa, there are about 400 tailings dams and dumps arising from gold mining in the Witwatersrand area of Gauteng province, and much of the available uranium today is in these. There are further tailings near Klerksdorp, close to the Vaal River. There is some radionuclide and heavy metal pollution arising from some of these, and acid mine drainage. Many of the tailings dams and dumps …
Tailing Disposal Methods and Tailings Dam …
Tailing Dams. The tailing dam should be situated where the slope of the ground enables the pulp to be retained with the minimum length of artificial embankment, since its height has to be raised at frequent intervals as the basin becomes full. The area enclosed must be large enough to allow of the settlement of the solid material, including the finest slime, at the maximum rate of inflow, so that clear water can be …
A Comprehensive Review on Reasons for Tailings …
In 1985, a tailings impoundment near Stava in northern Italy collapsed, killing 268 people and causing significant economic losses. The failure of the two tailings dams resulted in the release of approximately 240,000 m 3 of liquefied tailings [45, 74].When the tailings dams broke, the upper dam was over 34 m high, and the lower dam was 25 m high.

Assessing Risks of Mine Tailing Dam Failures
Tailings can be disposed in various ways but the most common practice is to deposit them as slurry in impoundments behind dams. This form of tailings storage facility is the focus of this paper, and the term TSF is used hereafter to refer to tailings dams. Figure 1 Santo Antonio ta ilings dam, Minas Gerais, TSF failure can have disastrous consequences to nearby communities, the environment ...

Following the catastrophic tailings dam failure at the Córrego do Feijão mining facility in Brumadinho, Minas Gerias, Brazil, which led to the loss of over 245 lives, and 25 missing people (as of May 2019), a group of institutional investors (now representing more than $13 trillion assets under management) have written to 726 extractive companies seeking greater disclosure on the management ...
MINING TAILINGS AND MANAGEMENTS - Tanta University
Dams, embankments and other types of surface impoundments are by far the . 7 most common storage methods used today and remain of primary importance in tailings disposal planning (Vick 1990). The particular design of these retaining structures is unique to a particular environment and mining operation. When considering the design of a tailings storage facility there are many parameters which ...
Environment compliance and report: Dams at NSW mines
Mine water management systems typically comprise various dams, including water storage dams, tailings dams, pollution control and sediment dams, and the associated infrastructure including pumps and pipelines. Prescribed dams The NSW Dam Safety Committee (DSC) is responsible for ensuring the safety of dams whose failure would cause serious community consequence. The DSC prescribes these dams ...

A systemic look at tailings dams failure process
various factors entering in the dams service life can then be individually discussed with a sens-itivity analysis. We then show where and how mitigative actions can benefit the most with prac-tical example. Attention is focused on Common Cause Failure (CCF) in operations, risk assess- ment, peer reviewing and inspections of tailings dams. on publicly available incident and accidents data from ...

tailings dam, all drainage must now be artificially added; stability of the tailings dam needs to be assessed in new ways as different possible failure mechanism need to be considered; and management of stormwater during construction must be carefully planned. This stone will present a case study highlighting how some of these challenges were addressed in a project where an HDPE liner was ...

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 many changes in operation and design parameters ...
