WE are the Canmet labs: Canada’s clean technology innovators.

For over a century, Natural Resources Canada’s research laboratories have provided global leadership in energy, materials and green mining clean technology research, development and innovation.

With over 500 world-class research scientists and engineers on 7 campuses, Canmet’s multi-disciplinary project teams have the skills and experience to move your projects from concept to commercialization.

We analyze, we create, we test and we replicate real-world applications, providing solutions and always working at the highest standard of excellence.

Mining is changing, and CanmetMINING is working in collaboration with others in Canada to facilitate the transition to green mining technologies and processes.

Our teams provide R&D solutions and scientific evidence for decision making in five key priorities: energy efficiency, enhanced productivity, waste management, water management and climate change adaption; we continue to innovate, for example, in artificial intelligence and automation; and provide specialized services and products to the mining community.

The list of initiatives is long, and our philosophy is consistent: we work to de-risk and accelerate the development and uptake of new and emerging transformative technologies and to strengthen the competitiveness and environmental performance of Canada’s mining sector.

Products and technologies developed by our labs are already changing how clean technology is used around the world.

We partner with industry, academia and governments to advance domestic and international research agendas and build a cleaner world.

Critical minerals

CanmetMINING is a centre of excellence in research on critical minerals. These minerals are used in renewable energy and clean technology, such as advanced batteries, permanent magnets, solar panels, wind turbines and small modular reactors. They are also used in advanced manufacturing, including defence and security technologies, semiconductors and consumer electronics and critical infrastructure.

Through a research, development and demonstration (RD&D) program, CanmetMINING is:

  • developing green, innovative processing technologies
  • helping Canadian critical mineral projects go into production
  • developing Canadian value chains (mineral extraction, intermediate processing, advanced manufacturing and recycling) for critical minerals

Battery minerals

Next-generation batteries are needed for green technologies, such as solar panels and electric cars. The minerals needed for these batteries include lithium, nickel, cobalt, graphite and vanadium. Among its many projects to develop these minerals, CanmetMINING is researching how to produce lithium-bearing minerals needed for batteries in an energy-efficient way. It is looking at how to more effectively extract lithium directly from brines, which are waters with a high concentration of salts. It is also developing a clean system to purify graphite.

Value from waste

Waste from existing mines often contains valuable minerals that were not extracted using conventional methods. CanmetMINING is determining the critical minerals found in mine waste across Canada. It is looking at how these critical minerals could be recycled from mine waste. It is also looking at critical minerals in old batteries and electronics from businesses and households, called post-consumer waste, to see whether these could be recycled.

Rare earth elements and other critical minerals

Rare earth elements are a group of 17 elements, including the lanthanide series in the periodic table of elements, together with scandium and yttrium. They are key components in many of the electronic devices that we use in our daily lives. CanmetMINING is researching new ways to produce these elements at a competitive cost.

Efficient mining practices and technologies

Using new technologies and learning best practices can make mining more efficient, lowering costs and benefiting the environment by using less energy. New technologies must be safe and ready to use, to minimize the risk for mining companies and their staff, as well as for the environment.

Digital tools

CanmetMINING is conducting research to develop digital tools to help companies navigate the regulatory processes in starting a mine. These tools will also make information about mines and mining easier to access for decision-makers, planners and the public. CanmetMINING is also developing tools to monitor environmental contaminants in real time.

Extreme mining environments

Many mines in Canada are very deep in the ground, posing challenges to extracting minerals and to workers’ safety. Innovative technologies can help find solutions to these challenges. That’s why some of CanmetMINING’s research and development focuses on ways to break rock underground without explosives. It is developing hoisting technologies that safely and efficiently bring ore, equipment and people to the surface. CanmetMINING is also investing in technology to monitor and manage ground stresses and seismic events, which can damage mines and threaten workers’ safety.

Climate change and mining

CanmetMINING is conducting research to benefit the environment, communities and economies. This includes finding ways to adapt mining processes to climate change and reducing the environmental impact of mining.

Climate change adaptation

Like many aspects of Canadian society and industry, mining must adapt to climate change. CanmetMINING is working to help industry adapt at all stages of the mining process, from developing new mines to reclaiming closed mines. Some examples of CanmetMINING’s research in this area are:

  • Improving performance of organic covers for mine site reclamation:
    Organic covers are used to prevent the exposure and contamination of certain metal-rich wastes/tailings to nearby ecosystems. However, organic covers are also vulnerable to changes in climate due to the sensitive microbial communities that inhabit them. For example, high temperatures can cause microbial communities to decompose organic covers at an increased rate, which could leave the waste/tailings at risk of becoming exposed. Therefore, it is important to understand and evaluate the reaction of different types of organic covers to changing climatic conditions.
  • Improving predictive tools and databases for environmental assessments of new mine projects:
    Mining operations produce a large amount of environmental and geochemical data. This kind of data could be very useful for informing regional environmental assessments and federal/provincial mining impact assessments. However, in order for data to be used in that way, it must be accessible, well-documented and reliable. That is why CanmetMINING is working in collaboration with others to develop a public-facing environmental geochemistry database that could be used by impact assessment reviewers and regulators, communities, consultants and industry to make informed decisions about the effects of mining operations on the planet.
  • Finding better ways to monitor and predict dust from mine sites:
    When dust from mining operations escapes and travels to surrounding areas, it might contaminate the food and water sources of nearby communities. With climate change, warmer and drier conditions could make dust a bigger problem. Dust monitoring guidelines do exist, but they are not tailored to the diverse ecosystems found in Canada. There is a particular lack of research on the effects of mine dust on Arctic ecosystems. Therefore, we need improved methods for measuring, monitoring and modelling dust in specific environments, such as the Arctic, to better manage ecosystem risks in changing climate.

Climate change mitigation

As well as adapting to climate change, the mining industry can take steps to limit its greenhouse gas emissions in order to reduce its contribution to climate change (mitigation). CanmetMINING is carrying out research to decrease carbon dioxide emissions. It is finding technologies that make the most efficient use of energy and generate the smallest carbon footprint. This includes recovering waste heat produced during mining to improve energy efficiency. Hydrogen fuel, a much lower-carbon solution, is being used in mining. CanmetMINING is supporting the development of new codes, standards and regulations to help companies transition to hydrogen technologies.

Responsible mining

CanmetMINING is working on projects to ensure that mines are managed responsibly. Research under this theme focuses on:

  • returning mining lands to functioning ecosystems for potential economic, environmental and community benefits
  • improving information for more effective regulations and for use in environmental impact assessments
  • mitigating environmental impacts through a reduction in waste, contamination and greenhouse gas emissions (see Climate change and mining, above)
