Methanogenesis in oil sands tailings: an analysis of the microbial community involved and its effects on tailings densification
DownloadSpring 2010
Densification of tailings slurries to mature fine tailings (MFT) is important in the oil sands industry for tailings inventory reduction, pore water recovery and tailings reclamation. The cause of methane release from the tailings pond of Shell Albian Sands (Albian) and the effects this process...

Fall 2011
Carbon dioxide (CO2) was shown as a promising alternative for oil sands tailings treatment with economical and environmental benefits. This thesis aims to understand the role of CO2 addition in settling and densification of oil sands tailings. In this study, CO2 was pressurized into two...

Fall 2013
ABSTRACT This research is an experimental design and numerical analysis of a novel technique of the vacuum consolidation of Mature Fine Tailings (MFT). A meso-scale test was conducted to examine the feasibility of the MFT dewatering process. Vacuum consolidation involves applying a negative...

Study of Bio-densification Process in Oil Sands Tailings: Modeling and Experimental Validation
DownloadFall 2012
Slow densification of mature fine tailings (MFT) is one of the major challenges in reduction of tailings inventory, pore-water recovery and reclamation of tailings for oil sands industry. Bio-densification is a new treatment method in which densification of tailings is accelerated through...

Synthesis and Characterization of Amylopectin-grafted Polyacrylamide (AP-g-PAM) Flocculants for Dewatering of Oil Sands Mature Fine Tailings (MFT)
DownloadSpring 2018
Oil sand mining continues increasing in Alberta and bitumen production from surface mining is predicted to reach 257,600 m3/day by 2026 (a 41.3% increase compared to 2016), generating a large amount of tailings that need to be stored in tailing ponds. The challenging part of tailing management is...

The Roles of Constituent Minerals and Residual Bitumen in the Filtration of Alberta Oil Sands Tailings
DownloadFall 2022
The dewatering of Alberta oil sands tailings is one of the most challenging problems faced by the oil sands industry. Despite significant efforts in the past several decades, the industry still lacks viable technologies that can quickly dewater and reclaim the oil sands tailings and eliminate...

The Use of Polyacrylamide as a Selective Depressant in the Separation of Chalcopyrite and Galena
DownloadSpring 2013
High molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable....
