Continuous accumulation of Mature Fine Tailings (MFT) is a major challenge to oil sands industry. To reduce the inventory of MFT through development of novel tailings treatment technologies, it is essential to understand the stabilization mechanism of fine solids in MFT. This project aims at characterizing fine solids of MFT. A novel method is developed in this study to understand characteristics of fine solids in MFT by studying their response to the changes in water chemistry and chemical treatment. Settling and rheological response of MFT to chemical additives is determined. Combined with solids characterization of the different layers of settled MFT, an enhanced understanding of stabilization of fine solids in MFT is gained. The knowledge generated through this study will provide a scientific basis for technology development of MFT treatment. / Chemical Engineering
