Anaerobic biodegradation of hydrocarbons in different oil sands tailings ponds: key microbial players and main activation pathway of hydrocarbon biodegradation
DownloadFall 2016
Anaerobic biodegradation of hydrocarbons is an important process in oil sands tailings ponds, which directly affects consolidation of tailings and extent of greenhouse gas emissions from tailings ponds. Since tailings ponds from different operators differ due to extraction process, age of...

Spring 2015
A large amount of fluid fine tailings (FFT) is stored in tailings ponds and is continuously accumulating from the extraction of bitumen from oil sands ore in northern Alberta. The FFT are high in water content and have a very slow dewatering behavior that requires many years for them to fully...

Effects of Enhanced Non-segregated Tailings, Root Hypoxia, and Salinity on the Growth of Commonly Used Oil Sands Reclamation Plant Species and Halophytes
DownloadFall 2023
In Alberta, Canada, oil sands mining activities have disturbed many boreal forest habitats and produced large amounts of tailings. Recently, a novel oil sands tailings management technology of the enhanced non-segregated tailings (eNST) has been developed, which uses polymers to accelerate...

Spring 2022
This study investigated the mechanisms driving the dewatering and strength behaviour of polymer amended treated (centrifuged and in-line thickened tailings/ILTT) deep tailings deposits undergoing seasonal weathering dominated by a) multiple freeze-thaw cycles and b) alternating freeze-thaw and...

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...

Using Surface Geopolymerisation Reactions to Strengthen Athabasca Oil Sands Mature Fine Tailings
DownloadFall 2015
Bitumen extraction from oil sands operation in Fort McMurray, Canada produces an immense quantity of slurry waste that is discharged to tailings ponds. These ponds now stretch over a region which is roughly 1.5 times the area occupied by Vancouver city mainly due to slow consolidation process of...
