An Examination of the Effect of Diluent on Microbial Dynamics in Oil Sands Tailings and the Mechanistic Insight on Carbon Dioxide-mediated Turbidity Reduction in Oil Sands Surface Water
DownloadFall 2019
Oil sands fluid fine tailings (FFT) are comprised of sand, silt, clay, residual organics, salt, trace metals and process-affected water (OSPW). In order to accommodate and remediate large amounts of FFT, a full-scale demonstration pit lake, where FFT was capped with a mixture of OSPW and fresh...

An Integrated Optimization Model for Strategic Open-Pit Mine Planning and Tailings Management
DownloadFall 2014
Badiozamani Tari Nazari, Mohammad Mahdi
A strategic mine planning model determines the best order of extraction and destination of material over the mine-life, in a way that maximizes the net present value of the produced minerals. In case of oil sands open-pit mining, further processing of the extracted oil sands generates massive...

Fall 2013
One of the current technologies used by the oil sands industry to reduce the volume of fluid fine tailings and create a dry landscape is production of CT (Composite Tailings) and NST (Non-Segregating Tailings). CT and NST are engineered tailings streams obtained by recombination of fines (MFT or...

Fall 2014
The extraction of bitumen from oil sands in Alberta, Canada, leads to the creation of tailings that are contained in lake-sized ponds under zero discharge policy. Stratification of tailings over time leads to the formation of mature fine tailings (MFT), an oil based emulsion containing residual...

Application of coagulation-flocculation process for treating oil sands process-affected water
DownloadFall 2011
Oil Sands Process-Affected Water (OSPW) is generated from oil sands operation processes such as mining, extraction, and upgrading. Currently, accumulated OSPW is temporarily stored in tailings ponds which are toxic to the environment and must be treated for either reuse or safe discharge in the...

Applications of Lime and Enzymes for Oil Sands Tailings Management: Dewatering and Mitigation of Methane Emissions
DownloadSpring 2023
The remediation of oil sands tailings is a crucial environmental aspect of the Canadian oil sands industry. Oil sands tailings management involves the endless storage of massive volumes of fluid fine tailings (FFT). The slow gravity settling of tailings, the release of toxic compounds, and the...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Bioremediation of oil sands process affected water sourced naphthenic acid fraction compounds
DownloadFall 2020
Current development of Alberta’s oil sands region requires large volumes of water, leading to an abundance of oil sands process affected water (OSPW). OSPW contains naphthenic acid fraction compounds (NAFCs) which have been found to contribute extensively to OSPW toxicity. Degradation of this...

Fall 2011
Fluorescence technology was examined as an analytical tool for identifying naphthenic acids in process-affected water. The fluorescence signal from process-affected water was narrowed down to the extractable organic acid fraction, known to contain naphthenic acids. A characteristic intensity...

Fall 2010
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...
