Spring 2015
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...

Spring 2019
This thesis aims to demonstrate the feasibility of using System Dynamics (SD) techniques to develop a transparent, open-source and reproducible model capable of simulating long-term soil water dynamics in a tailings-cap system subject to upward flux from a consolidating tailings substrate. The...

Development of compact fluorescent spectrometers and field deployable optical solids content monitoring devices
DownloadSpring 2015
Two techniques were used to develop industrial and environmental sensing devices: fluorescence spectrometry and light scatter. The focus of the thesis is to develop real-time, portable and economical sensors using these techniques for environmental detection and management of tailings slurries. A...

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...

Spring 2020
Albertan oil sands ores are becoming more difficult to process efficiently as the clay content of the ore increases and the grade of the ore worsens. A key to improving the extraction of bitumen from low-grade oil sands, thereby increasing the longevity of this critical resource, is reducing the...

Effects of Surface Contamination and Water Chemistry on the Behaviors of Illite, Kaolinite and Montmorillonite in Organic and Aqueous Media
DownloadSpring 2016
Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Clays, in tailings, are a significant ongoing environmental concern in the mining and oil sands production industries and clay...

Spring 2019
This research aims to improve oil sands tailings treatment by applying a combination of quick lime (calcium oxide) and anionic or cationic polymers in the flocculation process. A procedure including mixing lime, dilution of mature fine tailings (MFT) in the lime supernatant and addition of...

Estimation of the Evaporation Rate of an Isolated Water Microdroplet Subjected to Infrared Radiative Heating
DownloadFall 2014
A combined numerical-experimental investigation was performed to study the influence of infrared radiation on the evaporation of a single-component droplet in the range between 10 and 50 micrometers, under different environmental conditions of relative humidity and temperature of air. A numerical...

Estimation of the Life Cycle Greenhouse Gas Emissions of Bitumen-Derived Petroleum Fuels using Enhanced Solvent Extraction Incorporating Electromagnetic Heating (ESEIEH) and Toe-to-Heel Air Injection (THAI) Extraction Technologies
DownloadSpring 2019
There is increased focus on reduction of greenhouse gas (GHG) emissions to reduce global warming. Combustion of fossil fuels are a key contributor to emissions of GHG. Alberta is the largest hydrocarbon base in North America due to its oil sands deposit. Bitumen from oil sands is refined to...

Although evaporation is considered to be a surface phenomenon, the rate of molecular transport across a liquid–vapor boundary is strongly dependent on the coupled fluid dynamics and heat transfer in the bulk fluids. Recent experimental thermocouple measurements of the temperature field near the...
