To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...

In this study, a two-step flocculation method by combining anionic and cationic polymeric flocculants on the treatment of oil sands tailings was investigated. Compared to conventional flocculation by using a single anionic or cationic polymer, which has been a widely exploited procedure for...

Quartz crystal microbalance with dissipation (QCM-D) was used to study the zinc sulfide activation with silver, copper and lead. The interactions between calcium sulfate and minerals and gypsum nucleation on functional surfaces were investigated using a QCM-D, surface forces apparatus (SFA), and...

Pressure swing adsorption (PSA) processes are an industrially mature low energy consumption pathway for gas separations. Due to their performance being linked to the separation media, they provide an additional degree of freedom for process design. They are difficult to accurately model due to...

This work describes the effect that including a solvent in the reaction media of the autoxidation of Cold Lake bitumen has on the viscosity and also on the oxidation degree reached. The comparison of viscosity was performed both in the basis of equal residence time and equal oxygen conversion...

Metallurgical coke, a porous carbon material produced by carbonization of coking coal at high temperature, generally above 900 ○C, is an integral part of iron-making in the blast furnace. During iron making, coke serves several important roles in the blast furnace such as a source of energy, as a...

Bitumen extraction from oil sands operation in Fort McMurray, Canada produces an immense quantity of slurry waste that is discharged to tailings ponds. These ponds now stretch over a region which is roughly 1.5 times the area occupied by Vancouver city mainly due to slow consolidation process of...

Clay flocs exist in different streams of the oil sands extraction process and in tailings treatment. The clay fraction in these streams has a significant effect on design and operation of slurry pipelines, flotation efficiency, sludging in the separation vessel, froth treatment and tailings...
