Click to chatJames G. Speight in Heavy Oil Recovery and Upgrading 2019 5.5 The Oleophilic Sieve Process. An oleophilic sieve process (Kruyer 1983 2012) offers the potential for reducing tailing pond size because of a reduction in the water requirements. The process is based on the concept that when a mixture of an oil phase and an aqueous phase is passed through a sieve made from oleophilic materials
Click to chatToday the materials in these tailing ponds are seen as valuable and potentially usable. If mines extract them they can use them. By using standard existing technologies such as dredges dewatering boxes and centrifuges in different ways miners are able to recover these materials and recycle them back into the process or as raw material.

Extraction and upgrading/refining of mined bitumen are energy intensive operations that require significant fuel consumption resulting in emissions of greenhouse gases (GHG)carbon
Click to chat· Canada s Alberta s oil sands are one of the largest crude oil deposits on the planet. 1 Oil sands are a mixture of sand water and bitumena heavy oil too viscous to flow on its own. 2. A water-intensive extraction process is required to separate the bitumen from sand and large are these tailings ponds . As of 2018 these ponds collectively contained 1.25 trillion litres. 11 That s
Click to chat· A tailing extraction model (TEM) was established by combining the all-band tailing sand index (mainly PC5) the MNDTI index and the NDTIFe index. Compared with NDTI the TEM fully considers iron stain carbonate ion and water information of the tailing sand which are all important components.

Click to chat· 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.
Click to chat· The ruses don t always work. Every year an estimated 200 000 birds land on the oilsands industrial water bodies including tailings ponds according to a 2013 report by the University of Alberta s Oil Sands Monitoring Program. "It only takes a dime-size drop of oil to kill a " said Sarah Hechtenthal a wildlife biologist.

Click to chatThe two tailings ponds contain a total of 20.3 million tons of tailings (Fig. 9.9 a) their average uranium concentration being 67 g/t. Because the barren process solutions were neutralised only to pH 7–8 (instead of shifting pH to 10.5–11) during the milling process the TDS content exceeds 20 g/l in the liquid phase of the tailings.The tailings ponds were built without any proper base
Click to chat· For every barrel of bitumen extracted from the oil sands 1.5 barrels of tailings waste is produced. This large volume of tailings requires a large area for storage and the sheer size of tailings ponds can be an issue as they encroach on wildlife territory. Efforts are being made to reduce the impact that tailings ponds have on the environment.
Click to chat· Tailings Recovery Technology. Tailings water treatment technology The tailings pond is a large-volume sedimentation storage pond which can be set up on valleys slopes river beaches or flat ground by using topography and surrounded by dams. Drainage wells and drainage pipes are set in the pond or drainage ditches are set along the edges
