An Investigation of Millerite (beta-NiS) Flotation Behaviour in Alkaline Solutions in Cu-Ni Sulphide Mineral Flotation Separation
DownloadFall 2021
In the Sudbury Basin nickel deposit, the presence of a less common nickel sulphide mineral – millerite (beta-NiS) has a substantial impact on the Cu/Ni flotation separation efficiency. In this study, the flotation chemistry of millerite in alkaline solutions was investigated with pure minerals...

Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen Production
DownloadFall 2016
Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...

Overly-stable froth in mineral flotation columns are sometimes a problem for separation operations. Greater quantities of fine particles in the input slurry can contribute to froth that is too stable and overruns the equipment capacity. Currently, the best ways to deal with this problem are to...

Study of thin liquid film drainage in bubble-liquid-solid systems using integrated thin liquid film force apparatus (ITLFFA)
DownloadFall 2017
Interactions involving deformable surfaces reveal a number of distinct physicochemical characteristics that do not exist in interactions between rigid solid surfaces. The main focus of this thesis is to develop a unique fully custom-designed instrument, referred to as an integrated thin liquid...
