Evaluating the Biogeochemical and Geotechnical Behavior of Oil Sands Tailings in Pit Lakes and Mitigating Pit Lake Turbidity with Biofilms
DownloadFall 2023
Permanent storage and reclamation of oil sands mine waste (fluid fine tailings, FFT) in pit lakes has been proposed by industry. Pit lakes are considered best practice in terms of geotechnical stability, however, there are numerous challenges and knowledge gaps surrounding this proposed oil sands...

Soil cover systems are engineered barriers designed to isolate hazardous mine waste from climatic water and oxygen. Assessment of water flow at the interface between the atmosphere and the ground surface is paramount to successful cover design. For decades, cover systems were designed based on...

Spring 2022
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...

Using Co-Disposal Techniques to Achieve Stable “Dry-Stacked” Tailings: Geotechnical Properties of Blended Waste Rock and Tailings in Oil Sands and Metal Mining
DownloadFall 2021
Mine “tailings”, waste produced by the extraction process, are most typically stored in impoundments behind dams which are often constructed from the tailings themselves. These structures pose a serious geotechnical risk and are difficult to successfully reclaim at the end of mining. As highly...
