Emulsion Polymerization of Poly-(Methyl Acrylate) for Flocculation and Dewatering of Oil Sands Tailings.
DownloadFall 2020
This work adds to the continuing research efforts in Alberta to manage the accumulation of oil sands tailings and reduce the environmental footprint of oil sands’ operations. Oil sands tailings are unwanted by-products of surface-mining bitumen extraction processes. They are usually held in...

This research aims to improve oil sands tailings treatment by applying a combination of quick lime (calcium oxide) and anionic or cationic polymers in the flocculation process. A procedure including mixing lime, dilution of mature fine tailings (MFT) in the lime supernatant and addition of...

Extending Depletion Flocculation Phase Behavior Models to Partially Soluble and Aggregating Colloids—Asphaltenes
DownloadFall 2015
Mixtures of colloids + non-adsorbing polymers + good solvents are well known to exhibit multiphase behaviors that are driven by the depletion flocculation mechanism where one phase, designated a colloid gas, is largely comprised of polymer and solvent, while the other phase, designated a colloid...

Flocculation and dewatering of kaolinite suspensions and oil sands mature fine tailings using dual polymers
DownloadSpring 2015
The development of a method to consolidate and dewater Athabasca oil sands mature fine tailings (MFT) is one of the major challenges facing Alberta’s oil sands industry. This thesis presents studies performed on the flocculation and dewatering of kaolinite suspensions (the major clay component...

Spring 2020
The oil sands are a vital part of the provincial economy in Alberta and oil production in this sector produces large amounts of waste called tailings. The tailings consist of a slurry of clay suspended in process water with residual bitumen present. Reclamation of the land that the tailings ponds...

Rapid, efficient and economical water removal from fluid fine tailings represents a major challenge to many industries, including mineral processing, food processing, waste water treatment and oil sands extraction. In the absence of large-scale fine tailings processing facilities, there will be...
