Tailings ponds are massive earth structures used to store coarse and fine solids contained in the oil sands deposit and recover water back to the main processing plant. These ponds are temporary storage facilities and need to be reclaimed when no longer in use.Fine solids from tailings streams tend to trap large volumes of water, making pond reclamation challenging at best.
