Freezing Characteristics of Mine Waste Tailings and their Relation to Unsaturated Soil Properties
DownloadSpring 2018
The study investigated the feasibility of using the soil freezing characteristic curve (SFCC) to estimate the soil water characteristic curve (SWCC) in mine waste tailings as an alternative to traditional SWCC testing. Traditional SWCC tests are challenging and time-consuming to conduct, taking...

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...

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 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...

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...

Pennetta de Oliveira, Leonardo
Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Automating Information Flow in Hyperspectral Measurements for Soil Characterization in Tailings
DownloadFall 2015
In the first section of this thesis, two laboratory experiments conducted on tailing samples were evaluated using a structured qualitative analysis procedure. The process model of Suppliers, Inputs, Process, Output, and Customers (SIPOC) was used to study relationships amongst different parts of...

Applications of Remote Hyperspectral Sensing in the Characterization of Alberta's Oil Sands Tailings
DownloadSpring 2016
The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...
