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...

Theoretical study on reactivity of different sulfide collectors and their binding affinity toward Cu(II), Zn(II) and Pb(II) ions.
DownloadSpring 2016
Collectors are one of the most important ingredients of froth flotation in mineral processing, as they selectively render the desired minerals more hydrophobic than others. Current crop of sulfide collectors interact with almost all sulfide minerals. This necessitates the use of complicated...

Understanding zinc sulfide activation mechanism and impact of calcium sulfate in sphalerite flotation
DownloadSpring 2012
Quartz crystal microbalance with dissipation (QCM-D) was used to study the zinc sulfide activation with silver, copper and lead. The interactions between calcium sulfate and minerals and gypsum nucleation on functional surfaces were investigated using a QCM-D, surface forces apparatus (SFA), and...
