Spring 2011
Bitumen recovery by the water-based extraction process produces waste streams known as tailings. When discharged into the tailing ponds, the coarse solids in the tailings stream settle out quickly, while the fine solids accumulate over years of settling to a solids content of 30-35% by weight....

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...

Among all the competing methods to enhance the phase separation of water-in-oil emulsions in chemical industries, electric field is considered as one of the best treatment options. To better understand the mechanism by which electric field assists water droplets coalescence and the corresponding...

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 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...

Spring 2011
The presence of hydrodynamically generated air bubbles has been observed to enhance fine particle flotation in a high intensity agitation (HIA) flotation cell. In this study, the cavitation in an HIA cell, used in our laboratory, is studied by hydrodynamic computational fluid dynamics. Different...

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...

Fall 2010
The effect of slurry conditioning on bitumen recovery and bitumen froth quality has been studied by using three oil sands ores tested with a laboratory hydrotransport extraction system (LHES) and a Denver flotation cell. Tests with the LHES show that an increase in slurry conditioning time...

Madjlessikupai, Morvarid (April)
During separation of emulsified water from oil, a viscous intermediate layer builds up between water and oil phases. This layer which is referred to as rag layer disrupts emulsion destabilization and water removal. The present research is intended to better understand the formation of a rag layer...

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...
