What are tailings dams? | IndustriALL
What are tailings dams? 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.
Tailing Dam - an overview | ScienceDirect Topics
Various methods are used to raise the dam; material may be taken from the dried surface of the previously deposited tailings and the cycle repeated, or more commonly, the wall may be built from the coarse fraction of the tailings, separated out by cyclones, or spigots, the fines being directed into the pond (Figure 16.2 and 16.3).
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 are the waste resulting from the extraction of minerals and metals. 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.
