- Demonstration - Integration in situ of TGS Energy Efficiency Technology on Meadowbank Mining Site

Since 2018, Genset-Synchro Technology (TGS) has been developing and marketing an innovative power generation solution using diesel generators that substantially reduces fuel consumption, greenhouse gas emissions and production costs. and maintenance of diesel generators. Having initiated a demonstration of its GS500X model in the James Bay territory in the fall of 2018, TGS is currently working with Agnico Eagle Mines Ltd to demonstrate the energy efficiency potential of the TGS technology through the integration in situ of TGS technology into a generator at Meadowbank mining site. A summary of TGS technology and its impacts will be presented in the context of this project.

- Energy Profile of the Canadian Mining Sector

The energy profile of the mining sector is made up of several types of energy, including electricity, diesel, natural gas and propane, which serve a range of needs. The power demand for a mining site doesn’t remain constant, but can vary from mine to mine. This presentation provides an overview of the energy profile of the Canadian mining sector, including the types of energy it includes and their uses, as well as detailed examples for an underground mine and an ore processing mill. This information relates to energy management strategies.

- Recovering Thermal Energy in a Processing Mill

CanmetMINING has developed an energy recovery concept that may be a realistic solution applicable at several mining mills. The energy recovery project essentially involves capturing the thermal energy lost by an ore processing mill and using it to heat the fresh air in an underground mine ventilation system. A prefeasibility study conducted in partnership with Les Mines Opinaca Ltée and Le Groupe MISA at the Éléonore mine site revealed that the solution generated a significant reduction in fuel, thereby resulting in lower operating costs and greenhouse gas emissions. The presentation will provide an overview of the heat recovery concept and the potential savings it may generate.

- Technical and Economic Prefeasibility Study on the Integration of BLOK Units at Mining Camps

This study focuses on integrating photovoltaic solar energy generating and storage units at mining camps. The units to be studied are marketed under the name “BLOK.” The integration of these BLOK units would help partly reduce the mining camps’ dependence on diesel fuel, which would have a direct impact on the cost of generating electricity and reduce the facilities’ carbon footprint.

- Electricity Generation in Underground Mine Service Shafts

A feasibility study conducted in February 2019 on the possibility of generating electricity in the service shaft at the Westwood mine demonstrated the site’s energy potential and the return on investment. The project involves installing turbines over the fresh air duct in the service shaft and reusing the existing reservoirs to release the water back into the duct. This makes it possible to recover the heat lost at each level, considering that maximum power can reach 80 to 100 kW per level.

- Energy recovery from stale air extraction towers at Niobec mining site

As part of MISA's agile energy management program, Airex Industries was selected to conduct a pre-feasibility study and thereby assess the technical and economic viability to implement an energy-efficient solution for the Niobec mine. Considering the major issue of GHG emissions and volatile particles due to propane consumption as main source of heating for makeup air systems that supply the wells, Airex Industries suggest to set up the mine air exhauster with a combined filtration and heat recovery system to transfer energy to makeup air units.
