Accelerated Dewatering and Drying Treatment of Oil Sands Tailings by Electrical Resonant Auto-Transformer
DownloadFall 2014
Canada has world’s third largest oil reserves in the form of oil sands and 20% of those are easily accessible by surface mining. The hot water bitumen extraction process has been used since 1967 and the process produces vast amount of tailings which are stored in ponds. Tailings ponds pose a...

Effect of Addition Flowrates of Grafted Polymers on the Flocculation of Kaolinite Suspensions and Oil Sands Mature Fine Tailings
DownloadSpring 2023
Bitumen extracted from oil sands has been a major source of wealth for Canada, but it comes at a high price because the Clark hot water process generates large volumes of tailings which must be stored in ponds that threaten the environment. These tailing ponds must be treated to meet the land...

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...

Study on Adsorption of Inorganic-organic Hybrid Polymers and Flocculation of Oil Sands Tailings
DownloadSpring 2013
Two inorganic-organic hybrid polymers, Al(OH)3-polyacrylamide (Al-PAM) and Fe(OH)3-polyacrylamide (Fe-PAM) were synthesized and used in flocculating model tailings (5 wt% kaolin suspensions) and laboratory extraction tailings. For comparison, a commercial anionic flocculant, partially hydrolyzed...
