The incorporation of Cu interconnects into the manufacturing of integrated circuits has accompanied several modifications to the fabrication process and the associated material systems. The new fabrication process involves the development of dual damascene process, while the new materials systems...

Iron-cobalt alloys have been extensively studied as potential hard disk drive write head materials due to their potentially high saturation flux densities (~2.4T), low coercivities and ease of deposition. Iron-cobalt plating solutions have, however, been shown to have stability issues,...

The dominant materials used for solders in electronic assemblies over the past 60 years have been Pb-Sn alloys. Increasing pressure from environmental and health authorities has stimulated the development of various Pb-free solders. Two of the most promising replacements are eutectic Sn-Cu and...

The correlation between froth recovery and air recovery was established in a top-feeding mechanical flotation column. It was also found that the particles were stratified in froth layer, with hydrophobic particles (organic phase) concentrated in the upper region, and hydrophilic particles...

Non-aqueous extraction (NAE) process was explored as an alternative to the Clark hot water extraction process (CHWE) to recover bitumen from Alberta oil sands. The upshot of the NAE process is that it eliminates the latter’s environmental issues concerning high fresh water and energy...

Column flotation, as a selective separation process based on differences in surface properties, is used for a broad range of applications in the mineral processing industry, including metallic, non-metallic, and coal ores, as well as wastewater treatment over the last fifty years. Flotation is a...

The intimate association between bitumen components and clay minerals is an important feature of oil sands fine solids. These organically-modified clay minerals cause serious problems in Canadian oil sands production: hindering bitumen extraction, stabilizing water-in-bitumen emulsions, fouling...

The current bitumen extraction process has an alarming and increasing environmental impact that is forcing the industry to find a better way to produce oil. The solution that is in development is a solvent based bitumen extraction process. The removal of fines solids is still an important issue...

Adhesion of frozen granular materials on solid surfaces creates various problems for surface cleaning, reduces the carrying capacity of vehicles, and increases energy consumption for inland transportation. Here in the first part of this thesis, water content demonstrates to determine the adhesion...

Production of oil from the second largest oil deposit in the world, i.e., the Alberta oil sands containing approximately 13% of total proven oil reserves in the world (169.9 billion barrels), has been shown to be significantly influenced by clay minerals. Clay minerals in particular play a key...
