Probing Surface Heterogeneity, Electrochemical Properties and Bubble-Solid Interaction Mechanisms of Sulfide Minerals in Flotation
DownloadSpring 2017
The colloidal stability governed by various surface interactions including van der Waals (VDW) interaction, electrical double layer (EDL) interaction, hydrophobic interaction, and some other interactions, plays an important role in a wide range of natural phenomena and engineering applications....

Regenerable Composites for Removal of Organic Dye in Aqueous Media and Water in Heavy Oil and the Associated Interaction Mechanism
DownloadSpring 2018
Water plays an indispensable role in all aspects of life, including farming, domestic and industrial uses. In industries, water has been extensively applied in mining, production and surface treatment, producing a large quantity of contaminated water that threatens human health, endangers...

Fall 2018
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...

Study of the Intervening Thin Liquid Film between Deformable Oil Drop/Bubble and a Solid Surface in Oil Production
DownloadSpring 2022
Interactions involving deformable bubbles/oil droplets play a critical role in many industrial applications. Understanding the dynamic thin film drainage process and interaction forces involving deformable bubbles/oil droplets and solid surfaces in the oil sands extraction process is of great...

Surface Oxidation of Millerite and its Galvanic Interaction with Chalcopyrite in Collectorless Flotation
DownloadFall 2021
Surface analysis of millerite and chalcopyrite were performed to enhance the understanding of fundamental millerite flotation behaviour in single mineral and mixed mineral conditions. By studying the mineral surfaces without collector addition, the ambiguity about the origin of the formed...

Synergistic Role of Sodium Hydroxide and Sodium Citrate on Bitumen Slime Coating in Process Water
DownloadFall 2021
Sodium hydroxide (NaOH) is generally used as the primary processing aid in the water-based oil sands extraction for the recovery of bitumen. It was found by Syncrude Canada Ltd. that the combined use of sodium hydroxide and sodium citrate could effectively improve the bitumen recovery as compared...

Fall 2020
This study focuses on the synthesis process of gelatin-shelled microbubbles and their characterization. A new method to synthesize gelatin-shelled microbubbles was described. Briefly, Traut’s reagent was used to thiolate gelatin molecules; then sonication forces were placed at the water-air...
