Management of oil sands tailings from bitumen extraction operations remains a challenge for mineable oil sands producers. Promoting fine solids settling in tailings ponds is key to treating oil sands tailings. Present study explores two methods of tailings treatment – ATA process and polymer...

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...

Understanding mineralogy and surface properties of fine solids is vital in oil sands processing and tailings management. Fine solids in oil sands are often contaminated by tightly bound organic matter (OM) originally or during hydrocarbon removal, thereby increasing surface hydrophobicity and...

Probing Deformable Oil-Water Interfaces by Atomic Force Microscopy and Cascade Partial Coalescence Measurements
DownloadFall 2016
Phase separation of stable oil-in-water and water-in-oil emulsions poses major challenges for a variety of industries, including the petroleum industry. The stability and destabilizing of petroleum emulsions highly depend on interfacial properties such as surface/interfacial charges, interfacial...

To better understand bitumen conditioning stage in oil sands extraction process a flow cell was designed to study bitumen liberation directly from sand grains, using real oil sand ore. A high-grade oil sand ore was subjected to various water temperatures and pH values to examine the bitumen...

Many tailings treatment technologies rely on the use of water-soluble polyacrylamides (PAM) to flocculate fine solids. However, PAM-induced flocs are often loosely-structured and retain significant volume of water due to the hydrophilicity of PAM and fine clays in oil sands fine tailings....

Study of Thin Liquid Film Drainage and Interaction Forces in Organic Solvent for Liquid/Solid and Liquid/Liquid Interactions Using Dynamic Force Apparatus (DFA)
DownloadFall 2021
Properties of thin liquid films between two approaching droplets or between a droplet and a solid surface are critical for emulsion stability and for mineral flotation. If the thin liquid film is stable, no coalescence occurs, while an unstable film will lead to rupture and coalescence or the...

A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...

Interactions of finely dispersed abrasive particles in chemical mechanical planarization (CMP) slurries play a vital role in determining the polishing performance. In this study, coupled influence of hydrodynamic and colloidal interactions on the attachment of nanosized ceria (CeO2) particles to...
