Enhancing Gold Recovery from Nevada Double Refractory Gold Ores using a Novel Dual Bubble Generator
DownloadFall 2018
In this study, the influence of dual bubble generator on mineral flotation was investigated. A Venturi-based dual bubble generator was designed and characterized in both liquid-gas two-phase system and solid-liquid-gas three-phase flotation system. The dual bubble generator featured immediately...

Spring 2017
The formation of stable water-in-oil emulsions during oil sands extraction process causes a number of operational issues, such as equipment corrosion, storage and transportation problems. One common method for emulsion breakup in industry is to use chemical demulsifiers. The chemical demulsifiers...

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...

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...

Design and Application of Responsive Composite Particles for Multiphase Separations of Bitumen Emulsions in Bituminous (Oil) Sands Extraction
DownloadFall 2016
The development of more environmentally-friendly and cost-effective extraction and production technologies is a key to sustaining heavy oil and bitumen production. The high viscosity of the heavily degraded petroleum requires additional processing in order to recover such challenging resources...

Fall 2016
Caustic is the most commonly used process aid to improve processability of mineable oil sands ores in the Athabasca region. The addition of caustic adjusts the pH of the extraction process, disperses clays, and acts as a water softener. Understanding how these changes affect the fundamental...

Dynamic Demulsification Mechanism of Asphaltene-Stabilized Water-in-Oil Emulsions by Ethylcellulose
DownloadFall 2015
In previous studies, nontoxic and biodegradable ethylcellulose (EC) was shown to be capable of breaking water-in-diluted bitumen emulsions. Nevertheless, the demulsification mechanism of EC has not been correlated to its effect on the physical properties of stabilizing interfacial asphaltene...

Spring 2015
A multi-purpose settling column was designed to determine settling rate and sediment height allowing the in-situ measurement of yield stress and drainage without disturbing the sediment particle network. The settling column was applied to studying flocculation/densification of model oil sands...

Design, Synthesis, Characterization of a new pH-Responsive Copolymer and its Application in Oil Sands Tailings Treatment
DownloadSpring 2015
This research aims at treating mature fine tailings (MFT) with a novel pH-responsive copolymer poly (N,N-dimethylaminoethyl methacrylate-co-acrylamide-co-acrylic acid) p(DMAEMA-co-AM-co-AA). Compared with conventional polyacrylamide (PAM), the conformation and property of this novel copolymer can...
