Most of the gold that is produced by hydrometallurgical processes is recovered by cyanide leaching. However, the reactive nature of some minerals questions the applicability of cyanide technology for selected applications. The current research is designed to evaluate the cyanide technology as well as an alternative processing path for a particular material through extensive experimental program. The project will yield the mathematical models describing all chemical processes in each circuit, as well as mass and energy balances based on laboratory data and scientific reasoning.
The proposed study will develop seismic design guidelines for retrofitting deficient concrete bridge columns with sprayed fiber reinforced plastic (FRP). Seismically deficient bridge columns (with different aspect ratios and transverse reinforcement ratios) retrofitted with composites will be tested under reverse cyclic loading. The tests will determine various damage states in terms of strain and drift.
Many copper deposits contain significant amount of arsenic and antimony and being overlooked because of it. These impurities are currently subject to smelters penalty. Development of an efficient technology for removal of these impurities and converting them as sellable products will make a number of deposits economic that are currently not being mined. The current research will assist in identifying the most efficient technology for treating such complex minerals and to meet the rising demand for clear copper concentrates.
This research focuses on novel sensor-based algorithms for sorting rocks and categorizing them as good (valuable) and bad (worthless) rocks. The sensors in the sorter will see the rocks characteristics, whether its their color or atomic density or the desired element and send a command to a mechanical arm, for example, to separate the two types of rock from each other.
Iberian Minerals is a junior mining company, based in Canada. The Company recently acquired Mineworx Technologies, based in Vancouver, British Columbia and is now focused on various mining technologies. One such technology we are developing is an eco-friendly, non-cyanide based leach extraction for gold processing utilizing iodine as a complexing agent. The research and development undertaken will study the feasibility of a new approach to a sustainable process in gold mining, which will see an immediate positive ecological impact on pollution through the non-use of highly toxic cyanide.
A large number of civil engineering structures in North America have long survived their expected service life. As they continue to age, there is a significant demand to minimize damage under severe environmental impacts such as earthquake. The main objective of this project is to develop and validate vibration-based monitoring and control strategies using modern sensing technologies.
Today's modern industries aim at supplying premium quality products that can offer added performance value, lower weight, less environmental impact, decreased manufacturing and maintenance costs, increased durability and safety, and eventually higher customer satisfaction and market competitiveness. To achieve these goals, new-engineered materials such as glass fiber reinforced polymers (GFRPs) are rapidly replacing traditional single materials such as steel and aluminum.
A laser-optics vehicle profiling system will be designed and developed in this project. The image of a laser line projected onto the surface of a vehicle from a vantage point will be used to make metric measurements on the vehicle and to develop a 3D model of it.
It is conjectured that this setup would work superior to the existing time-of-flight laser profilers in terms of accuracy, resolution, and speed of operation.
Multiple laser-optics scanners located at optimal locations in an inspection station can provide a panoramic 3D model of the vehicle and also provide measurements.
Traditionally, the microchips that power our communications technology use electrical signals to compute, transfer, and store information. Silicon photonics (SiP) is an emerging field, where structures fabricated on those same microchips replace electrical signals with optical ones, enabling exciting new applications such as optical and wireless communications, bio/environment-sensing, and computing.
This project is to help SaskEnergy characterize the pollutant transport behaviors under the remediation process of SVE through advanced modelling system. Such a modelling system employs a series of stochastic analysis methods to quantify the random features in the subsurface at Cantuar site such as the porosity, hydraulic conductivity and so on. Then, relationships (or functions) between SVE control variables and pollutant concentrations are generated through advance statistical methods.
