IntroductionNature of TailingsProduction of TailingsTailings CharacteristicsTailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient, nor is it possible to reclaim all reusable and expended processing reagents and chemicals. The unrecoverable and un在tailingsfo上查看更多信息

What Are Tailings Ponds? Environmental Impact

Tailings are stored in large engineered dam and dyke facilities called tailings ponds. Tailing ponds enable water to separate from sand, clay and bitumen for re-use in bitumen extraction. Water is continuously recycled from tailings ponds back into the extraction process, reducing use of fresh water from the Athabasca River and other sources
