This research is a follow up to preliminary studies reported by Beier and Sego (2008) and the objective is to investigate laboratory scale dewatering of oil sands total tailings using cross flow filtration technology. A laboratory experiment was setup in Oil Sands Tailings Research Facility and...

Piles are commonly used in the Canadian Arctic as a foundation solution. Steel pipe shaft pile, which is a conventional pile type in the Arctic, is placed in an oversized pre-drilled hole and then the annulus is backfilled with gravel slurries or grout designed to cure (i.e., a process called...

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 paper examines changes in climate with respect to permafrost and engineering design in Arctic regions. Current understanding of climate changes, predictive modeling, and climate data were studied. Inconsistencies and differences were noted, discussed, and evaluated using comparisons of the...

The extraction of sulfide-bearing waste rock can contribute to the generation of acid rock drainage (ARD). ARD is the effluent generated due to the oxidation of sulfide minerals which can be toxic to the receiving environment. Waste rock material which contains potentially acid-generating (PAG)...

Natural convection with high cooling effects is of increasing interest in cold region geotechnical engineering. To study natural air convection in a highly-permeable porous medium, convective and conductive heat transfer experiments were carried out using an insulated cylindrical tank filled with...

Natural attenuation refers to the observed reduction in contaminant concentration via natural processes as contaminants migrate from the source into environmental media. Assessment of the dimensions of contaminant plumes and prediction of their fate requires predictions of the rate of dissolution...

One of the current technologies used by the oil sands industry to reduce the volume of fluid fine tailings and create a dry landscape is production of CT (Composite Tailings) and NST (Non-Segregating Tailings). CT and NST are engineered tailings streams obtained by recombination of fines (MFT or...

A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...
