This research project aims at improving the recovery of precious metals from fine-grained resources using ultra-fine grinding process. The project involves testing three different ore samples to quantify the benefits of HIGmill grinding on mineral recovery. A comprehensive HIGmill model for optimization purpose will be developed based on bench-scale tests. The developed HIGmill model could […]

While the benefits of uranium production bring economic and strategic advantages for Saskatchewan and Canada, the legacy of its tailings, waste rocks, flooded mines, and industrial wastewaters are the drawbacks. To safeguard both human and environmental health, the mining waste streams need to be treated prior to their release to the environment. The current research […]

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 […]

Sensor Based Sorting is a relatively new technology for the mining industry. The ability to use sensor to classify particles or bulk materials ahead of expensive downstream grinding and separation has many benefits including reduced energy and water usage, reduced operating costs and improved metal recoveries. Testing to assess sorting for a mineral deposit is […]

With growing urgency towards Environmental, Social, and Corporate Governance (ESG), mining companies are trying to position themselves to take advantage of the massive demand for metals to come with the energy transition. To place their products in the marketplace and retain their social license to operate, miners are committing to net-zero carbon emission targets. With […]

The mining industry is integral to modern living standards and related technological advancements. However, mining operations are complex and capital-intensive ventures that rely on the coordination of a number of moving parts to remain viable. Moreover, external forces such as evolving global economic, socio-environmental and geopolitical factors also present significant levels of risk to modern […]

Canada is recognized as one of the leading nations worldwide in terms of mining production, attributing a major component of the success to the mineral exploration field. Companies engaged in mineral exploration have been increasingly more aware of the importance of health and safety systems, yet high numbers of reported incidents remain. Mineral exploration efforts […]

Block cave mining is generally considered the preferred mining method for deeper and lower grade copper and gold deposits. The body of practical knowledge related to the impacts that mass mining methods have on the surrounding environment is limited by the challenges imposed by the ever-increasing size of caving operations, and the difficulty to transfer […]

CO2 geo-sequestration is an efficient approach to reduce CO2 emission and achieve zero carbon emission with minimum impact on economic growth and people’s wellbeing. This project focus on optimizing carbon utilization in heavy oil reservoirs and CO2 geo-sequestration in the underline saline aquaifer with three key objectives: optimizing CO2 injection in heavy oil reservoir to […]

This research project evaluates the environmental performance of two tailings management areas at a decommissioned mine site in Ontario. The tailings areas are decommissioned with a water cover and continue to be managed and monitored with ongoing water treatment. The project revisits groundwater modelling that was conducted prior to the decommissioning of the site and […]

Heavy oil (high viscosity oil) is trapped underground. Cold heavy oil production with sand (CHOPS) is an enabling technology to extract heavy oil through wormholes forming around wellbore. There are thousands of CHOPS wells in Saskatchewan and Alberta with low primary oil recovery. Cyclic solvent injection (CSI) enhanced oil recovery process stands out as one […]

This research work will establish a systematic workflow for analyzing transient equilibrium foamy oil phase behavior by coupling the m-CCEC tests, depletion rate and presence of water-in-oil emulsion from microscopic viewpoint which are seldom performed for heavy oil. It will provide a strong connection and comparison with previously studies which was conducted in the absence […]
