In recent decades, hydrodynamic cavitation has been used to enhance fine particle flotation recovery in mineral engineering. Such an increase was mainly attributed to the generation of flocs/aggregates of fine particles during the hydrodynamic cavitation process. However, the mechanism of floc...

In this study, a novel synthesis of proteinaceous microbubbles (MBs) was introduced in an effort to substantially lengthen the short lifetime of the sonochemically-synthesized microbubbles using surface-treated proteins. Bovine serum albumin (BSA) as a representative protein, was treated with...

The inadvertent activation of sphalerite by lead ions have been noticed and studied for decades. In this study, flotation behavior of sphalerite upon lead activation was studied. Sodium hydrogen phosphate was applied as a main depressant to test its effect on improving Pb-Zn selectivity. Surface...

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...

Abundance of low rank coal and increasing demand for energy provide an incentive for upgrading the low rank coal due to their high moisture and oxygen content. Various analyses were done to study the effect of the hydrothermal treatment on the physical and chemical structure of coal. Treatment of...

Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...

Water-in-oil (W/O) emulsions create many processing problems in petroleum industry. The enhanced stability of droplets and poor separation of emulsions are often associated with the interfacial accumulation of asphaltenes. The complex nature of asphaltenes has complicated the understanding of...
