US3869384A - Tailings disposal system for tar sands plant,

This invention has to do with the treatment of the tailings stream from a hot water extraction plant for recovering bitumen from tar sand. This stream comprises water and coarse and fine solids. The stream is fed into a mined-out cavity to settle the coarse solids. Some of the decanted water from the cavity is transferred to a large settling pond for clarification.Tailingsfo Deposition Methods of Tailings,Spigot disposal (normally subaerial) is used where the tailings are discharged generally around the perimeter of the tailings facility (ring dyke construction) to create a beach between the embankment and the supernatant pond (Ritcey 1989). This generally means the pond is completely surrounded by beached tailings (figure 4).Tailings - Wikipedia,Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids separate.
