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...

Characterization of mature fine tailings in the context of its response to chemical treatment
DownloadFall 2010
Continuous accumulation of Mature Fine Tailings (MFT) is a major challenge to oil sands industry. To reduce the inventory of MFT through development of novel tailings treatment technologies, it is essential to understand the stabilization mechanism of fine solids in MFT. This project aims at...

CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands Extraction
DownloadSpring 2020
Interfacial properties at the oil-water interface are of key importance to various operations in the petroleum industry, especially in the aqueous-based heavy oil recovery process. However, different operation stages often require different interfacial properties, which could be conflicted with...
