Fall 2010
Oil sand deposits are found at three depths; shallow, intermediate, and deep. Shallow deposits are processed by surface mining while deep deposits are processed using thermal extraction methods. There are currently no production methods to extract oil sand at intermediate depths. The...

A cationic thermal sensitive polymer, polyN-isopropylacrylamide-co-N-[3-(Dimethylamino)propyl]methacrylamide (CP) of different molar ratios, known as CP05 and CP10 was synthesized in-house. By doping aluminum hydroxide (Al(OH)3) colloids into CP during the polymerization process, a novel hybrid...

As one of the most critical steps to recover valuable particles from a slurry using flotation, knowledge of the drainage of the thin liquid film between an air bubble and a solid surface is required. The main focus of this thesis is to develop and use an integrated thin film drainage appratus...

A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction Gangue
DownloadSpring 2015
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

The technique of Inverse Gas Chromatography (IGC) was employed for the study of the interactions between various organic solvents with various types of the major inorganic materials (clay minerals and sand) found in Alberta’s oil sands. Heat of adsorption (-∆H) was measured for each solvent with...

Environmental concerns about water-based extraction necessitate the development of an alternative non-aqueous extraction method. One of the challenges that any non-aqueous extraction process is encountered is the elimination of suspended fine solids from solvent-diluted bitumen. This study...

At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids whether suspended in aqueous or non-aqueous liquids continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

An Alternate Indicator System for Nutrient Supply as Part of Ecosystem Function, a Component of Reclamation Success in the Athabasca Oil Sands Region
DownloadFall 2017
Northeastern Alberta faces the challenges of reclaiming a vast area that has been disturbed my oil sands mining, cumulatively 896 km2 and increasing as of December 2013. The limited resources available for reclamation and expensive costs of undertaking the process necessitates that reclamation be...

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...

The surface mining of oil sand ore requires the use of huge shovels and 400-tonne capacity trucks to transfer the mined ore to the slurry preparation plant, where water and additives are added to the crushed ore. The oil sand slurry is then transported to the extraction section and simultaneously...
