In mineral processing froth flotation is the most important technique to recover and separate different minerals. However, the flotation process deteriorates significantly with low efficiency and selectivity when mineral particles are smaller than 20 µm. Low flotation kinetics of fine hydrophobic...

Traditionally in pipeline steels and welds, ultrasonic testing (UT) has been used for crack and/or flaw detection. The work presented in this Thesis explores the use of this technique to characterize the microstructure of pipe steels. Ultrasonic velocity calculations, for shear and longitudinal...

Asphaltene is the most difficult fraction of bitumen and heavy oil to upgrade, as it has low H/C, high molecular weight and metal content. Asphaltenes are insoluble in paraffinic solvents, and undergo aggregation and coke formation during refining and cracking processes. No attention is usually...

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...
