Tailings Fact Sheet
As the tailings slurry is deposited in the impoundment, the water separates from the heavier sand and silt particles and collects to form a decant/reclaim pond on the surface of the impoundment newmontgoldcorpVersion 5 June 2019 The tailings pond water is then recycled back into the milling process for reuse The tailings are contained 2015年8月6日 A TSF is often a tailings pond, where the tailings are stored in process water Ponds are engineered using dams, which is why you’ll also often hear the term “tailings dam,” and the surrounding environment (for example, Tailings Management 101: An Introduction to One of Who Regulates Tailings Storage?

The fundamental Parameters you need to know2016年12月19日 In tailings pond, the residues are usually deposited as waterbased slurry before recycle/reuse or discharge to environment To prevent the discharge of processaffected water of tailings pond to surface water directly, tailings ponds were first introduced to store the residue before discharge or reuseProcess effluents and mine tailings: sources, effects and management waste to Alberta’s tailing ponds, and each day industry needs to store 25 million new litres of tailings 10 Today, Alberta’s liquid tailings now make up more than 118 trillion litres of Alberta’s tailings ponds NRDC
