Gold is a precious metal with numerous possibilities for use and recycling. Although its primary use remains in jewelry, it is also highly valued for its unique properties, such as exceptional electrical conductivity and resistance to corrosion. It is an essential metal in electronics and advanced technologies, playing a key role in the energy transition.
Gold is also a safe haven for investors and central banks. The recycling of gold, influenced by price fluctuations, includes not only jewelry but also end-of-life electronic components.

Primarily used in steel production, iron is a metal heavily utilized in various sectors such as automotive, construction, and medicine.
Nearly 98% of extracted iron is used to produce steel, which is fully recyclable, contributing to resource and energy savings. Other iron derivatives, such as iron powder and iron oxide, are used in specialized applications.

Although it is not a metal, graphite shares similar properties, such as good thermal and electrical conductivity.
It is found in both natural (34%) and synthetic (66%) forms, used to make electrodes, batteries, lubricants, and in foundry activities. The graphite recycling market is still modest but growing, with applications such as brake linings and thermal insulation. The Lac des Îles mine in Quebec is the only active graphite producer in Canada.

Nickel makes up 8% to 13% of stainless steel components, providing strength and protection against corrosion and extreme temperatures.
This infinitely recyclable metal retains its qualities after each reuse cycle. Approximately 68% of the nickel in end-of-life products is recovered. In 2018, it was estimated that 57% of all nickel extracted was still in use, thanks to its durability and recycling efforts.

Québec and Canada are already producing lithium, notably through Sayona, which operates a mine in Abitibi as well as another in Manitoba.
However, the extraction potential remains significant due to the numerous spodumene deposits across the territory. In 2023, more than $339 million was invested in the exploration of lithium, graphite, and rare earth elements, reflecting the growing interest in these metals essential to the energy transition.
