A Model Study on Water Soluble Polymeric Nanofibers for Rapid Flocculation and Enhanced Dewatering of Fine Oil Sands Tailings Simulated Through Kaolin
DownloadFall 2018
Nanofibers are fibers with diameters lower than 100 nm, traditionally made from natural or synthetic polymers. Properties of nanofibers, such as low density, controllable surface functionality, and high surface area to volume ratio, allowed researchers to use them in a multitude of applications...

Since European settlement of the Canadian Prairies there has been substantial loss of wetlands. This loss occurs in large part due to drainage by private agricultural operators seeking to boost the productivity of their land. Policy makers now seek not only to conserve wetlands and prevent...

A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction Gangue
DownloadSpring 2015
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

The redevelopment of understories is an often-overlooked aspect of forest restoration following anthropogenic disturbances. In my research I explored the feasibility of actively restoring forest understories through seedling planting. First, I examined the quality of nursery-grown boreal shrub...

This research comprises four integral parts. Each part focuses on one aspect of the general problem of drug delivery by respiration. The morphological features of human respiratory tract, the dynamics of inhaled pharmaceutical particles, and the mechanics of inhaler devices are particularly taken...

Aggregate Resource Extraction: Examining Environmental Impacts on Optimal Extraction and Reclamation Strategies
DownloadFall 2014
Aggregate resources are naturally occurring deposits of sand, gravel and crushed stone that are integral components to the construction of everything from roads and sidewalks, to hospitals and schools. Mining these resources can release deleterious sediments, salt and chemicals into watercourses,...

Amylopectin-graft-hydrolyzed-poly(methyl acrylate) (AP-g-H-PMA) Flocculants for the Treatment of Oil Sands Tailings
DownloadSpring 2020
The extraction of bitumen from the Alberta oil sands reserves has long been a major economic contributor to the Canadian society, but the impact this industry has had on the environment has raised concerns worldwide. The main problems are how to reclaim the area and reduce the number of tailings...

An Examination of the Effect of Diluent on Microbial Dynamics in Oil Sands Tailings and the Mechanistic Insight on Carbon Dioxide-mediated Turbidity Reduction in Oil Sands Surface Water
DownloadFall 2019
Oil sands fluid fine tailings (FFT) are comprised of sand, silt, clay, residual organics, salt, trace metals and process-affected water (OSPW). In order to accommodate and remediate large amounts of FFT, a full-scale demonstration pit lake, where FFT was capped with a mixture of OSPW and fresh...

An Integrated Optimization Model for Strategic Open-Pit Mine Planning and Tailings Management
DownloadFall 2014
Badiozamani Tari Nazari, Mohammad Mahdi
A strategic mine planning model determines the best order of extraction and destination of material over the mine-life, in a way that maximizes the net present value of the produced minerals. In case of oil sands open-pit mining, further processing of the extracted oil sands generates massive...

An Investigation of Potential Weed Management Practices and Multivariate Assessment Parameters for Alberta's Oil Sands Reclamation Efforts
DownloadSpring 2018
Reclamation efforts that promote the re-establishment of native tree and plant communities subsequent of large-scale oil sands mining land disturbances are crucial in restoring natural ecosystems. It is important that reclamation procedures capable of facilitating the establishment of native...
