Oil sands tailings, composed of water, sands, silt, clay and residual bitumen, is produced as a byproduct of the bitumen extraction process. The tailings have poor consolidation and water release characteristics. For twenty years, significant research has been performed to improve the consolidation and water release characteristics of the tailings. Compliance Won’t be Easy In December , the University of Alberta’s Oil Sands Tailings Research Facility (OSTRF) and the Canadian Oil Sands Network for Research and Development (CONRAD) hosted the First International Oil Sands Tailings Conference (IOSTC) in Edmonton, Alberta, where more than three dozen papers were presented on various aspects of tailings management.
Remediating mine tailings requires isolating heavy metals and other contaminants from the environment. Hence, they are often capped with impermeable covers constructed of expensive engineered materials to contain the contaminants on site. However, engineered, supposedly impermeable, covers fail in arid climates because they degrade overtime due to expansion and contraction of compacted clays. Static liquefaction and strength loss of tailings dams due to undrained failure has become a topic of interest in tailings management following the Fundão and Mount Polley tailings dam failures. Static liquefaction is the sudden loss of strength when loose soil, typically granular material such as sand or silty sand, is loaded and cannot drain.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an gs are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water.

[Michael J Rowell] -- Fourth report of program to study methods for the establishment of vegetation on tar sands tailings. The remediation and revegetation of tailings sands produced during the extraction of bitumen from the Athabasca tar sands present numerous challenges, from the sheer volume of tailings produced to the quality of the tailings (toxicity, high salt, low nutrients) to support growth.

One of the problem areas of the hot water process for tar sands extraction arises from the clay mineral fines, which comprises from less than 1% to over 15% of the mined material. Silver-berry and buffalo-berry are two such shrubs which are being tested as potential candidates for the revegetation of the oil sands tailings in northeastern Alberta.
Associated with the roots of silver-berry and buffalo-berry are two symbionts the N2-fixing actinomycete, Frankia, and the vesicular-arbuscular mycorrhizal (VAM) fungi. Remediation and revegetation of tar sands composite tailings containing naphthenic acids and high salt using alder-Frankia s W.

James G. Speight, in Heavy Oil Recovery and Upgrading, The Oleophilic Sieve Process. An oleophilic sieve process (Kruyer,) 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.
Oil sands tailings ponds are engineered dam and dyke systems used to capture oil sand sand tailings contain a mixture of salts, suspended solids and other dissolvable chemical compounds such as acids, benzene, hydrocarbons residual bitumen, fine silts and water. Large volumes of tailings are a byproduct of bitumen extraction from the oil sands and managing these tailings is one of.
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 solids from tailings streams tend to trap large volumes of water, making pond reclamation challenging at best.

Only one application of fertilizer/year is necessary after the first year, when two are needed. SGS provides tailings management, environmental sampling, testing and bird deterrence solutions tailored specifically for the oil sands industry.
Our operational procedures, testing of extraction, tailings stream and in-situ pond material are conducted under the strict quality control and regulatory compliance that has made SGS a world leader. The information provided in this fact sheet is to be used by oil sands mine operators as a guide to understanding Alberta Environment’s expectation regarding dam safety and progressive reclamation (including revegetation) of active oil sands tailings dams.

Tailings. A blend of MFT and sand used to dispose of fine tailings. DDA – Dedicated disposal area. An area for disposal of fines to be reclaimed. FFT - Fluid fine tailings. The clay-dominated fine mineral solids contained in the water run-off from the (mainly sand) tailings discharged from the oil sands bitumen extraction process.
Tailings were sampled and "hot spots" containing high concentrations of lead were excavated and placed in an engineered, state-approved waste repository. The remainder of the tailings contain relatively low concentrations of metals and were reclaimed by capping with soils and revegetation.
Oil sands deposits mined from the Athabasca Basin produces a variety of tailings streams that are mostly comprised of coarse silica sand. Contained within the sand is a sizeable fraction of fines with trace concentrations of iron, vanadium and titanium oxides as well as numerous rare-earth minerals.

The tailings stream is, therefore, composed of a large amount of water and some bitumen that escapes the extraction process, while the solids are mainly sand.
