The extraction of bitumen from oil sands is an energy and water-intensive process that produces a tailings byproduct containing sands, clays, water, and residual bitumen. Larger particles eventually settle out of the tailings, but fine particles – stabilized by the residual bitumen – remain...

Removal of emulsified water is a challenge in oil sands and heavy oil processing. The flocculation and coagulation of emulsified water droplets depend on the interactions between the water droplets covered mainly by asphaltenes and oil-contaminated fine solids. To quantitatively evaluate the...

Bubble-particle interactions are ubiquitous and crucial to mineral fotation. The bubble-particle attachment process is mainly governed by three surface forces: van der Waals (vdW), electrical double-layer (EDL), and hydrophobic (HB) forces. Atomic Force Microscopy (AFM) has become the most...

Sodium hydroxide (NaOH) is used as a chemical additive to enhance bitumen recovery from oil sands by surface-mining extraction process. The addition of NaOH adjusts the pH of the slurry water to pH ~8.5 (approximate pH of process water). The change in pH of oil sand slurry affects the process...
