Abstract:

Disposal of oil sands tailings in ponds is a common method used by oil sands operators to manage the large volume of tailings generated from oil sands mining. This study considered a large tailings pond with an 11 km long ring dyke that was constructed of permeable tailings sand and equipped with drains and seepage collection ditches designed to collect process-affected water (PAW) from the dyke. The effectiveness of this seepage collection system was examined at the downgradient end of the tailings pond and dyke system using a focussed field investigation supported by groundwater flow modelli

Abstract:

ABSTRACTThe Athabasca oil sands deposit is the largest reservoir of crude bitumen in the world. Recently, the soaring demand for oil and the availability of modern bitumen extraction technology have heightened exploitation of this reservoir and the potential unintended consequences of pollution in the Athabasca River. The main objective of the present study was to evaluate the potential impacts of oil sands mining on neighboring aquatic microbial community structure. Microbial communities were sampled from sediments in the Athabasca River and its tributaries as well as in oil sands tailings po

Abstract:

In the past decade, the large tailings pond (Mildred Lake Settling Basin) on the Syncrude Canada Ltd. lease near Fort McMurray, Alta., has gone methanogenic. Currently, about 60%-80% of the flux of gas across the surface of the tailings pond is methane. As well as adding to greenhouse gas emissions, the production of methane in the fine tailings zone of this and other settling basins may affect the performance of these settling basins and impact reclamation options. Enumeration studies found methanogens (105-106MPN/g) within the fine tailings zone of various oil sands waste settling basins. SR

In order to test the viability of oil sands aquatic reclamation techniques, yellow perch (Perca flavescens) were stocked into three experimental ponds.

These indicators included survival, age, spawning periodicity, condition factor, gonad size, fecundity, and liver size. Indicators generally showed patterns consistent

Abstract:

In Alberta’s Athabasca oil sands region (AOSR), over 1.25 billion m3 of tailings waste from the bitumen extraction process are stored in tailings ponds. Fugitive emissions associated with residual hydrocarbons in tailings ponds pose an environmental concern and include greenhouse gases (GHGs), reduced sulphur compounds (RSCs), and volatile organic compounds (VOCs). Froth treatment tailings (FTT) are a specific type of tailings waste stream from the bitumen froth treatment process that contains bioavailable diluent: either naphtha or paraffins.

Abstract:

Abstract Large quantities of toxic wastewater are produced in the processing of oil sands. The toxicity appears to be due primarily to polar organic carboxylic acids (naphthenic acids). These surfactants occur naturally in oil sands and are released during the caustic hot-water extraction process. Relatively high concentrations of suspended particulate matter, bitumen, and dissolved solids, as well as low dissolved oxygen levels, may also contribute to the toxicity of the water. Tailings pond water can be detoxified by rapid chemical treatments which involve coagulation at a pH between 4.5 - 5

Abstract:

Fine tails, the resulting fine waste from oil sand processing, undergoes large-strain consolidation in tailings ponds. Its consolidation behaviour must be analyzed using a large-strain consolidation theory, which requires the determination of the relationship between the void ratio and hydraulic conductivity. Conventional measurement techniques are not suitable for fine tails, and a special slurry consolidometer, with a clamping device to prevent seepage-induced consolidation, was designed to determine the hydraulic conductivity of the fine tails and nonsegregating fine tails sand slurries.

Abstract:

The present method of oil sands tailings disposal results in a tailings pond with a fine tailings zone that will take many decades to consolidate fully. The fine tailings accumulate as a result of the segregating characteristics of the tailings stream. Nonsegregating mixes of total tailings are desirable to prevent or greatly reduce the formation of a fine tailings zone. This study investigated the use of lime and sulphuric acid to prevent segregation of the tailings stream. Two batches of Syncrude tailings were tested. These averaged 48 and 55% solids and 17% fines (< 44 μm). The hindered

Abstract:

The bitumen extraction process from Athabasca oil sands ore produces large quantities of toxic processed water as tailings. The oil industry has reduced the demand for fresh water in the extraction process by recycling this tailings water. Continual recycling increases the toxicity of tailings water many times over, and poses a serious threat to surface and groundwater quality. For a sustainable expansion of Canada’s oil sands industry, it is essential to develop a technically practicable and economically feasible tailings water treatment technology.

Abstract:

Oil sands tailings ponds harbor large amounts of tailings resulting from surface mining of bitumen and consist of water, sand, clays, residual bitumen, and hydrocarbon diluent. Oxygen ingress in these ponds is limited to the surface layers, causing most hydrocarbon degradation to be catalyzed by anaerobic, methanogenic microbial communities. This causes the evolution of large volumes of methane of up to 104m3/day. A pyrosequencing survey of 16S rRNA amplicons from 10 samples obtained from different depths indicated the presence of a wide variety of taxa involved in anaerobic hydrocarbon degrad

Abstract:

Approximately 20% of Canada's oil supply now comes from the extraction of bitumen from the oil sands deposits in northeastern Alberta. The oil sands are strip-mined, and the bitumen is typically separated from sand and clays by an alkaline hot water extraction process. The rapidly expanding oil sands industry has millions of cubic metres of tailings for disposal and large areas of land to reclaim. There are estimates that the consolidation of the mature fine tails (MFT) in the settling ponds will take about 150 years. Some of the settling ponds are now evolving microbially produced methane, a

The Athabasca oil sands in northeastern Alberta, Canada represent the second largest petroleum reserve in the world. The process of extracting bitumen from the oil sands uses huge volumes of water, drawn from sources in the Athabasca River basin, and numerous mining companies operate adjacent to the river. Oil sands process-affected water (OSPW) from open pit mining is placed in large settling basins or tailings ponds that have the potential to leak. The goal is to eventually reclaim the tailings ponds to become functional ecosystems. Natural outcrops of oil sands in contact with surface water

The production of crude oil from the Canadian oil sands has generated tailings ponds that contain oil sands process-affected water and oil sands fluid fine tailings (FFT).

Here we discuss various mechanisms governing the vertical mixing of suspended solids in an end pit lake. Depending on the depth of the water cap, wind waves can cause mixing between the water cap and the FFT. Other potential mixing mechanisms incl

Abstract:

Linear wave theory and wave hindcasting are applied to derive an expression for the depth of water needed to prevent the wind-wave-induced suspension of sediments in mine tailings ponds. The depth is expressed as a function of four factors: the threshold velocity, the wind velocity, the fetch over which the wind blows, and a factor based on the statistical distribution of wave heights. This study was motivated by the need to determine the thickness of water required to prevent the suspension of sludge solids in existing and proposed tailings ponds at Syncrude Canada Ltd.'s oil sands plant.

Abstract:

After oil sands separations, settling of clays from aqueous tailings can be promoted by additives such as Ca2+ salts. However, if the liberated water is then recycled, these same additives in the water interfere with bitumen recovery in the separator. Therefore, we have tested CO2-triggered switchable additives to see whether they can switch back and forth between a form that is suitable for the separation stage and a form that promotes tailings ponds settling. CO2-triggered switchable additives can reversibly change water chemistry merely by introduction and removal of CO2, a benign trigger.
