Electrokinetic Dewatering Of Oil Sands Tailings, Yu Guo

Electronic Thesis and Dissertation Repository

Oil sands tailings are the final product of oil sands processing and in the form of slurry with very low solid content. After sedimentation, due to a low hydraulic conductivity of the tailings, both dewatering and consolidating the tailings are difficult. Since electrokinetic (EK) is an effective method to consolidate low permeability soils, the objective of this study is to assess the effectiveness and efficiency of EK dewatering of MFT, a man-made geomaterial. Two series of tests were conducted in this study. In the first series, four EK cell tests were performed on oil sands tailings to measure the electroosmotic …
