Settling the tailings pond question
These vast ponds have grown to 220 square kilometres and now hold about 1.2 trillion litres of murky, contaminated water that will take many decades to settle out. About ten years ago, operators and researchers began seriously looking at ways to speed up the separation of fluid fine tailings (FFT) – mostly clays – from the water.

Impact of inundation range of overtopping dam break of tailings pond
Tailing ponds are a major hazard source with the risk of dam breaks. To predict the impact of tailings pond dam breaks more accurately, one needs to quantitatively understand the dam-breaking process of the tailings reservoir and its downstream impact. This study is based on an old tailings pond that is about to be put out of service and the …
