Canadian Natural Resources - Managing Tailings

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).
