Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

In bitumen recovery from oil sands, a percentage of the bitumen is lost to tailings. The effect of fugitive bitumen on fines settling and consolidation in tailings ponds remains controversial. In the current study, the settling performance of mature fine tailings (MFT) in response to flocculant...

Combined Adsorption and Biodegradation Processes for Oil Sands Process-Affected Water Treatment
DownloadFall 2014
The oil sands process-affected water (OSPW) generated from bitumen extraction of oil sands by industries in Northern Alberta, Canada, is a great environmental concern because of the OSPW toxicity in the environment. This toxicity has been attributed to a group of alicyclic and aliphatic compounds...

Background The emergence and spread of antibiotic resistance in pathogens have led to a restriction on the use of antibiotic growth promoters (AGPs) in animal feed in some countries. The potential negative after-effects of a ban on AGPs could be mitigated by improving animal intestinal health...

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...

This research aims to assist in the assessment of tailings management technologies through the development of a dynamic simulation model. The developed model (TMSim) incorporates the mine plan, various stages of dewatering including classification, pre- and post-deposition dewatering, and an...

Cationic and Anionic Dual Polymer Pairs for Mature Fine Tailings Flocculation and Dewatering
DownloadSpring 2016
The accumulation of oil sands tailings poses serious environmental issues in Alberta, Canada. In the tailings ponds, the fine clays and residual bitumen form the so-called mature fine tailings (MFT) which contain 30~40 wt% fine solid particles primarily below 44 µm in size, 1~3 wt% residual...

The by-product slurry resulting from the bitumen extraction process from oil sands sources, known as tailings, holds substantial amount of water along with clays and fugitive bitumen. Current polymer-based dewatering technologies are centred on acrylamide-based polymers such as polyacrylamide...

This thesis focuses on formulating and analyzing non linear models for microbial dynamics vis-a-vis human and environmental health. Firstly, we develop and investigate a stoichiometric organic matter decomposition model in a chemostat culture that incorporates the dynamics of grazers. This...

Certain areas of oil sands in Canada are mined and processed for bitumen production using hot water processes that produce a slurry waste, referred to as tailings. Sand particles in tailings quickly settle and produce mature fine tailings (MFT), which are stored in large tailing ponds. Currently,...
