Occurrence and physicochemical properties of organic matter found in phosphate ores

The proposed research project is aimed at detailed characterization of organic matter found in certain types of phosphate ores. The presence of organic compounds often complicates the beneficiation of such ores to produce a fertilizer-grade phosphate concentrate. Further advances in the treatment of such problematic phosphate ores require a thorough understanding of the nature and distribution of organic compounds within phosphate ores.

Corrosion inhibitor for potash mining and processing plants

We propose to mitigate corrosion in potash mining and processing plants by introducing corrosion inhibitor to potash brine solutions. We will screen and formulate a cost-effective corrosion inhibitor that is compatible to potash mining and processing operation, but does not degrade quality of potash products and still provides high corrosion inhibition performance.

Pilot scale process flow sheet development for sustainable recycling of lamps from the waste stream

Lamps and lighting products are the most commonly used electrical product around the globe. With the improvement in lamp technologies, from incandescent bulb to compact fluorescent lamp to LED bulbs, the products have grown complex and hence they require an improved recycling process. In general, lamps consist of various valuable metals such as iron, copper, aluminium, chromium, silver, gold and some hazardous metals such as lead, mercury and arsenic. It also contains plastic and glass.

Investigation of turbulent three-phase flows in the FLSmidth nextSTEPTM flotation cells using CFD-PBM-kinetic simulation framework

The proposed research is aimed at both understanding and improving the flotation equipment design through the development and application of comprehensive multiphysics platform, which has the potential to create more accurate, fundamental basis for modeling, optimization, and scale-up of industrial flotation processes, based on physics rather than empirics and intuition.

Développement d'un outil d'analyse technico-économique des modes de restauration et évaluation de l'impact de la végétation sur le bilan d'eau des digues en stériles miniers du parc à résidus de la mine Canadian Malartica

Les mines à ciel ouvert produisent une importante quantité de rejets accumulés sur le site minier en période d?exploitation. Une fois les activités de la mine terminées, le site doit être restauré de manière à ne plus générer de contamination et à être remis dans un état visuellement acceptable. Afin d?assurer une restauration efficace des aires d?accumulation des rejets miniers, la mine Canadian Malartic teste directement sur son site, depuis quelques années, diverses méthodes de restauration pouvant être utilisées.

Continuous Leaching and Recovery of Silver Sulphide Ore in Cupric-Ammonia Thiosulfate Medium

The conventional way of treating silver ore is using cyanide during leaching process, also called cyanidation. Due to the inherent toxicity of cyanide and the potential hazard toward human and environment, cyanidation has raised more public concerns in our society. More and more regions have strict regulations or prohibition on using cyanide. An alternative leaching method for silver ore is necessary. Among all the proposed alternatives, thiosulfate leaching is the most promising one. Low toxicity and low cost make thiosulfate leaching attractive.

Development of predictive erosion-corrosion models for potash slurry flow

Electrochemical corrosion is the most common source of plant downtime in the Chemical Processing Industries (CPI); in the Province of Saskatchewan, the Mining Industry plays a very significant role in CPI. Mineral processing plants handle electrolytic and abrasive materials that can cause very significant structural damage due to electrochemical corrosion and wear.

Waste heat recovery in aluminium smelters: technical and economic analysis

Aluminium smelter are energy intensive and not particularly energy efficient, as most of the energy required to produce aluminium is lost along the production line. This is the reason why it is mandatory to perform a detailed analysis of the thermal wastes produced in these factories. The main objective of this project is to investigate the solutions to recover the thermal wastes and to convert them into useful power.

Review of Dry Comminution Technologies and Innovations

Goldcorp recently announced a new initiative referred to as H2zero with the goal of reducing water usage in their mining operations by 80 to 100%. Mineral processing and specifically comminution and mineral separation are the main consumers of water. This research focuses on dry comminution technologies and represents a first step towards advancing dry comminution as part of a longer term goal and research intersect. A literature review will be conducted to compile information about existing and novel dry comminution technologies.
