Technical Report: Design and Evaluation of Tailings Dams ...

By far the larger proportion of ore mined in most industry sectors ultimately becomes tailings that must be disposed of. In the gold industry, for example, only a few hundredths of an ounce of gold may be produced for every ton of dry tailings generated. Similarly, the

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity

The dangers of tailing dams on the planet - Clean Mining

Nov 25, 2019 · Most mines opt for the cheaper ‘upstream method’ where the tailings themselves are piled up, with more tailings added to increase the height of the dam as mining operations continue. Dams built using the upstream method are more likely to collapse because, once dried, the tailings used to create the barrier become less dense and more sand ...
