    Historically, tailings were disposed of in the most convenient manner, such as in downstream running water or down drains. Because of concerns about these sediments in the water and other issues, tailings ponds came into use. The sustainability challenge in the management of tailings and waste rock is to dispose of material, such that it is inert or, if not, stable and contained, to minimise water and energy inputs and the surface footprint of wastes and to move toward finding alternate uses.

    Tailings are a mixture of water, sand and clay found naturally in oil sands that remain following the mining extraction process. Tailings are transported by pipeline and deposited into ponds, where the majority of the solids – mostly sand – settle to the bottom. The remaining fluid (water and clay) is called Fluid Tailings (FT). As the solids in the FT begin to settle, the FT densifies ...
