Fundamental Studies of the Surface Properties of Millerite under Different Pulp Potentials and Water Chemistry
DownloadSpring 2019
Millerite (NiS) is one of the less common nickel-bearing minerals that is typically formed as a replacement for pentlandite. Due to the scarcity of millerite, its flotation behavior is not well understood in literature. In this study, the surface properties of millerite were investigated. Cyclic...

Spring 2013
In this study, the effect of three polymer flocculants, polyacrylamide (PAM), Magnafloc 1011 (MF) and Al(OH)3-polyacrylamide (Al-PAM), on the settling of mineral freshwater and saline tailings was investigated. The settling of tailings significantly depends on solution salinity, polymer...

Fall 2014
In this study, the interactions between pentlandite and gangue minerals (i.e. serpentine, olivine, magnesite) were investigated by directly measuring the zeta potential distributions. In addition, an atomic force microscope (AFM) was used to measure the interaction forces between a silicon...

Investigation and Optimization of Corrosion-resistant Electroless Ni-P Coating in Steam-assisted Gravity Drainage System
DownloadFall 2020
The boosting energy demand has propelled the increasing utilization of oil and gas resources, but severe corrosion occurs on traditional carbon steel materials. Driven by the harsh service conditions in steam-assisted gravity drainage system (SAGD) operations, a promising corrosion-resistant...

Probing the Molecular Interactions of Asphaltenes in Organic Solvents Using a Surface Forces Apparatus
DownloadSpring 2014
A fundamental understanding of the stability of water-in-bitumen emulsions stabilized by surface active agents requires a good description of the molecular interactions between the different materials in contact. Of these surface active agents, asphaltenes and oil contaminated fine solids are...

Surface Interaction Mechanisms between Deformable Bubbles and Hydrophobic Surfaces in Aqueous Solutions
DownloadSpring 2018
Deformable bubbles in complex fluidic systems are crucial components in a variety of traditional and emerging industrial processes, where their surface interactions with hydrophobic surfaces play an important role in realizing the targeted functionalities. In this project, a bubble probe atomic...

The development and characterization of electroless Ni-P nanocomposite coatings and investigation of their corrosion resistance
DownloadFall 2018
The Steam Assisted Gravity Drainage (SAGD) system is a commonly employed method to extract crude oil in Alberta. The slotted liners of the SAGD system are made of L80 carbon steel, which is prone to the corrosion attack in the corrosive serving environment containing H2S and CO2. To reduce the...
