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....

Blasting is widely used in mining operations as the primary comminution process to reduce the in-situ rock into fragmented material suitable for the subsequent transport and processing. The energy used is released from an explosive by detonation and transferred to the rock mass via a shock front...

Collecting information is of vital importance for the development of a mineral project. The capital costs of mining projects are high and there is significant risk due to the available data. At all stages of a project, from exploration to mine closure, decisions need to be made that are based off...

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...

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,...

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 Improved Approach to Production Planning in Oil Sands Mining Through Detailed Analysis and Simulation of Cycle Times
DownloadFall 2018
The objective of this thesis is to develop, implement and verify a theoretical framework based on detailed analyses and simulation of truck and shovel cycle times in open pit mining, placing an emphasis on the hauling component of the cycle. The goal is to improve the generation of accurate and...

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...

An evaluation of hitchhiker seedlings with native boreal species as a revegetation tool of industrially disturbed sites in Alberta, Canada
DownloadSpring 2020
Herbaceous forbs hitchhiked, or co-grown, with a woody species, is a solution to establish both native woody and herbaceous species at recently disturbed sites. The broad study objectives were to (1) assess the growth of fireweed hitchhiked with three deciduous woody species and one conifer over...

Fall 2014
The extraction of bitumen from oil sands in Alberta, Canada, leads to the creation of tailings that are contained in lake-sized ponds under zero discharge policy. Stratification of tailings over time leads to the formation of mature fine tailings (MFT), an oil based emulsion containing residual...
