Tailings dams are used to store water and waste that come as by-products from the mining process. They can be huge in size, as big as lakes, and reach 300 meters high. Tailings storage facilities can pose a threat to local wildlife and ecosystem, especially in the case of failure. In Canada, the Mount Polley […]

Le traitement du drainage minier (DM) est une activité clé pour la durabilité des opérations minières. Idéalement, un système de traitement passif devrait être conçu pour fonctionner pendant nombreuses années, sans nécessiter une maintenance majeure. Des études récentes ont montré l’efficacité de ce système pour les sites miniers abandonnés et éloignés en voie de restauration. […]

Mining has been a major, invaluable source of wealth and employment for Canada. However, mining activities involve the release of heavy metals into the environment through its process tailings. These metals are highly toxic to the environment, but they are also recoverable and have high market value for other applications. There are various treatments to […]

Downhole turbines are drilling tools that use the flow of downgoing drilling fluid inside the drillstring to turn a solid or hollow drive shaft, which can power or actuate other drilling tools such as turbodrills, electrical generators, hydraulic motors, and a variety of other mechanical, electrical or hydraulic devices. There are many versions of downhole […]

Epithermal-type deposits are small, high-grade gold and/or silver ± base metal deposits that formed shallowly in the upper crust and are frequently associated with hydrothermal fluids related to deeper emplaced, large tonnage, low-grade precious metal ± base metal porphyry deposits. Bringing the deeper emplaced deposits to surface requires processes such as erosion of overlying rocks. […]

The process of an oil and gas reservoir being “soured” by hydrogen sulphide is complex due to the many operations (e.g. changing production methods and waterflooding). The phenomena of souring occurs in most reservoirs were secondary or enhanced oil/gas recovery takes place. Hydrogen sulphide casues a number of operational and safety problems such as scaling, […]

Oil reservoir souring is the production of toxic hydrogen sulfide by sulfate-reducing microorganisms (SRM) through naerobic respiration supported by organic electron donors present in oil fields. In recent years, nitrate injection has merged as a promising green biotechnology that has been proven effective in controlling sulfide production in oil fields. This strategy relies on inducing […]

This work aims to protect oat oil and produce new formulated products for food, cosmetics, pharmaceutical, and household care applications. Specifically, nanocellulose and food-grade cellulose derivatives will be used to stabilize oat oil-in-water emulsions which will be dried into oil powders using spray drying. The powders appear dry but are >90% liquid oil and can […]

La République démocratique du Congo (RDC) est un pays particulièrement riche en ressources naturelles. Les diamants, le cuivre ou encore l’or sont autant de ressources que l’on peut retrouver dans le sol de ce pays, particulièrement dans les régions situées à l’est. Cependant, ces régions sont également connues sur la scène internationale comme étant le […]

Mud pulse telemetry is a widely used technology for measurement-while-drilling (MWD) in the oil and gas sector. MPT signals are used in real-time drilling application to provide insight about the pressure, temperature, drill bit direction and deviation, and transmit logging data about the surroundings to improve the reservoir drilling economic efficiency. It transmits signals using […]

In BC open pit porphyry mines, pit wall deformation rate has been closely monitored to evaluate the stability of open pits and determine proper operational response. This research aims to improve our understanding towards the deformation behaviours of pit walls considering both the slope characteristics and external influence factors. The project will collect a large […]

AJ Min Inc. is developing a novel technology to recover gold from tailings material. The technology requires little energy, little to no reagents, and little to no additional water. Past testwork has indicated that this technology can recover significant amounts of gold from some tailings material, and that the recovered gold can be upgraded. This […]
