    Tailings is the material that remains after bitumen is extracted from the oil sand. It is a mixture of sand silt clay water and residual hydrocarbon. Tailings are stored in in-pit or out-of-pit tailings placement areas. As it is deposited the coarser components settle rapidly and are used in the construction of sand beaches or other landforms.
