Fine fluid tailings (FFT) are a by-product created during the extraction of bitumen from oil sands mining operations. Over 975 million m3 of FFT are currently being stored in tailings ponds in the Athabasca oil sands region (AOSR) of Alberta, Canada. These tailings cause industrial and...

Bitumen recovery by the water-based extraction process produces waste streams known as tailings. When discharged into the tailing ponds, the coarse solids in the tailings stream settle out quickly, while the fine solids accumulate over years of settling to a solids content of 30-35% by weight....

This dissertation studies efforts by self-declared grassroots groups, organizations, and campaigns that promote Canadian oil through traditional and social media. Since the emergence of the Ethical Oil campaign following the publication of Ethical Oil in 2010, similar groups and organizations...

Large volumes of fluid fine tailings (FFT) from oil sands mining operations pose difficult engineering challenges because they do not readily dewater and due to their fluid state, require containment. A common approach to reduce FFT volume by water removal is to treat the clay suspension with a...

Sustainable pavement infrastructure is an essential component for the economic development for any country. The quality of materials of pavement layers impacts the long-term performance of pavement structures. Low quality granular materials can result in pavement deformation and reduced pavement...

The extraction of bitumen from oil sands using non-aqueous extraction (NAE) techniques has the potential to replace currently used water-based extraction techniques. High bitumen recovery rates, lower freshwater requirements, and elimination of afterward tailing ponds are all advantages of...

Fines , especially clays, in oil sands ores have a significant impact on the processability of the ore, or performance of bitumen extraction from the ore. The main focus of this research is to understand the effects of the type and wettability of clays on the performance of bitumen extraction...

Non-aqueous extraction (NAE) of bitumen from oil sands has recently regained interest as a replacement for the commercial, water-based extraction method. NAE has the potential to alleviate all the current water-induced extraction challenges such as high fresh water consumption, high heat...

Managing fluid fine tailings (FFT) is a defining challenge of the oil sands industry in Alberta due to low solids content, and extremely slow self-weight consolidation. One technology to increase the solids content of these tailings is centrifugation to produce centrifuged fluid fine tailings...
