Atomistic Approach towards Sodium Citrate Role on Surface Properties of Silica and Clay Minerals
DownloadFall 2022
The use of sodium citrate as a secondary processing aid in combination with caustic significantly improved bitumen recovery, specifically in poor oil sands ores. The role of sodium citrate on wettability alteration of solid surfaces, benefiting bitumen liberation as well as improving bitumen...

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...

Molecular Dynamics Study of the Interactions between Cations/Carbon Dioxide and Selected Mineral Surfaces
DownloadSpring 2018
Undoubtedly, we need to become increasingly aware of the changes and problems introduced to our environment. Oil sands industrial waste disposal and greenhouse gas emission are the two major by-products of the industrial processes that cause environmental concerns, such as huge tailing ponds and...

Spring 2017
Oilsands tailings are a waste product comprising primarily a stable alkaline suspension of clay in water. This waste product of oilsands mining is environmentally hazardous to store and expensive to safely dispose of. This work presents two novel ideas for dealing with the waste. The first is...

Role of Sodium Hydroxide in Bitumen Extraction: Production of Natural Surfactants and Slime Coating
DownloadSpring 2015
Alkaline environment by addition of NaOH in bitumen extraction process often shows a positive effect on bitumen recovery from Athabasca oil sands by mining-extraction method. NaOH ionizes organic acids in the bitumen to produce surfactants. These species are essential for bitumen liberation....
