Fall 2013
Chitosan, a naturally occurring polymer, was studied as a potential selective depressant in the differential flotation of sulfide minerals. In single mineral flotation tests, chalcopyrite, galena, sphalerite and pyrite were depressed to different extents. However, in the differential flotation of...

Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...

Feather Keratin Derived Sustainable Biosorbents for Adsorption of Heavy Metal Ions from Water
DownloadSpring 2023
Water is the epicenter of sustainability and has an essential part of the existence and development of the ecosystem and socioeconomic pillars. However, one in every three humans does not have access to clean drinking water around the globe and heavy metal ions pollution is the major contributor....

Synthetic oligodeoxynucleotides containing unmethylated CpG motifs (CpG ODNs) are powerful stimulators of innate and adaptive immune responses, exerting their activity through the interaction with endolysosomal Toll-like receptor 9 (TLR9) expressed by antigen presenting cells (APCs). The strong...

Methanogenesis in oil sands tailings: an analysis of the microbial community involved and its effects on tailings densification
DownloadSpring 2010
Densification of tailings slurries to mature fine tailings (MFT) is important in the oil sands industry for tailings inventory reduction, pore water recovery and tailings reclamation. The cause of methane release from the tailings pond of Shell Albian Sands (Albian) and the effects this process...

Multifunctional Self-Healing Hydrogels Based on Natural Polymers for Biomedical Applications
DownloadFall 2019
Hydrogel is a chemically or physically cross-linked hydrophilic three-dimensional (3D) polymer network. Classic hydrogels with irreversibly cross-linked polymer networks cannot heal after rupture, leading to degradation and deterioration in their functions over time. In contrast, self-healing...

In nature, the molybdenite ores are frequently associated with copper sulfide minerals such as chalcopyrite, and the flotation separation of copper-molybdenum (Cu-Mo) sulfides largely relies on the use of toxic and hazardous depressants such as cyanides, Na2S/NaHS. It is desired to replace these...

Pressurized Hot Water Hydrolysis of Shrimp Shell and Chicken Feet for Value-added Compounds Production
DownloadSpring 2023
The interest in the valorization of animal by-products such as shrimp shell and chicken feet has been growing as a sustainable approach to produce valuable biopolymers such as chitosan and collagen, that is also in line with the sustainability concept. These biopolymers could find applications in...

The Use of Polyacrylamide as a Selective Depressant in the Separation of Chalcopyrite and Galena
DownloadSpring 2013
High molecular weight polyacrylamide (PAM) was tested as a potential selective depressant in the differential flotation separation of galena and chalcopyrite using potassium ethyl xanthate (KEX) as a collector. In single mineral flotation, PAM depressed chalcopyrite while galena was floatable....

Spring 2016
In this study, a two-step flocculation method by combining anionic and cationic polymeric flocculants on the treatment of oil sands tailings was investigated. Compared to conventional flocculation by using a single anionic or cationic polymer, which has been a widely exploited procedure for...
