Spring 2010
Understanding mineralogy and surface properties of fine solids is vital in oil sands processing and tailings management. Fine solids in oil sands are often contaminated by tightly bound organic matter (OM) originally or during hydrocarbon removal, thereby increasing surface hydrophobicity and...

Fall 2011
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...

A study of the colloidal stability of mixed abrasive slurries of silica and ceria nanoparticles for chemical mechanical polishing
DownloadFall 2011
Slurry stability is an important factor in Chemical Mechanical Polishing (CMP) efficiency. However, few studies have been done in this respect. In settling tests at pH 4, adding various amounts of ceria to colloidal silica slurries was shown to change the stability of the resulted mixed abrasive...

Theoretical study on reactivity of different sulfide collectors and their binding affinity toward Cu(II), Zn(II) and Pb(II) ions.
DownloadSpring 2016
Collectors are one of the most important ingredients of froth flotation in mineral processing, as they selectively render the desired minerals more hydrophobic than others. Current crop of sulfide collectors interact with almost all sulfide minerals. This necessitates the use of complicated...

Characterization of mature fine tailings in the context of its response to chemical treatment
DownloadFall 2010
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...

Mineral carbon sequestration (MCS) is a type of carbon storage based on natural rock weathering processes where CO2, dissolved in rainwater, reacts with alkaline minerals to form solid carbonates. Although MCS has advantages over other carbon storage techniques, an economic MCS process has not...

Spring 2010
Filtration performance of mineral concentrate is mainly controlled by solid particle size and surface hydrophobicity. Filtration of coarser particles with more hydrophobic surfaces produces better filtration performance characterized by higher filtration rate (U) and lower final moisture content...

A Molecular Dynamics Approach towards the Interfacial Properties of Sulfide- and Clay-Minerals
DownloadSpring 2019
Interfacial properties have a regulatory role in processes which involve the coexistence of different phases. Although such macro-scale properties are determined by the intrinsic nature of the interface-sharing phases, it is possible to alter them in favor of the process objectives. This,...

The confined impinging jet reactor gives efficient mixing performance as required for fast reactions. In this work the mixing performance of CIJR is characterized through three measures: estimates of the energy dissipation, micromixing efficiency based on the yield of a homogeneous...

Fall 2012
Two major kinds of natural surfactants are released during oil sands extraction: carboxylic acids (naphthenic acids) and sulfonic acids. In this study, commercial surfactants were used as standards to establish the suitable analytical methods with optimized experimental and instrumental...
