Zinc and Lead

At Glencore Canada, we proudly operate one of the country’s most integrated zinc and lead businesses, with operations in Ontario and Quebec. Our impressive portfolio includes CEZinc, General Smelting of Canada, and Kidd Operations – three entities that share a rich history, all originating from Noranda Mines Limited.

From the depths of underground mining to the intricacies of refining and lead alloy production, we are dedicated to delivering the essential zinc and lead that help fuel modern life and drive emerging technologies forward.

Zinc is not just a mineral; it’s a cornerstone of modern society, with diverse applications that touch nearly every aspect of our lives. Some of its vital roles include: 

• Corrosion Resistance: The annual global cost of corrosion is estimated at US$3.2 trillion, which exceeds 3% of the world’s GDP. The World Corrosion Organization estimates that applying current corrosion control technologies, like zinc coatings, could save approximately US$400 billion per year.

• Renewable Technology: Zinc is crucial in renewable energy technologies, with a 100MW solar panel park – enough to supply 110,000 homes – requiring 240 tonnes of zinc and a 10MW offshore wind turbine requiring four tonnes of zinc.

• Public Health and Agriculture: Over one billion people worldwide are classified as zinc deficient. Zinc contributes to immune health and is used in fertilizers that boost crop yields and food security.

• Circularity and Recycling: Zinc is highly recyclable. The end-of-life recycling rate in Europe and North America exceeds 50%. For rolled zinc, the recycling rate is above 95%.

Being active in the primary production, marketing, and recycling of zinc and lead, means we are well-positioned to meet the growing demand across automotive, energy storage, agriculture, infrastructure, and renewable energy sectors.

CEZinc – Modernizing North America’s zinc refining

Located in Salaberry-de-Valleyfield, Quebec, CEZinc is the largest zinc refinery in eastern North America and a key supplier to markets across the continent.

• In 2023, Glencore took a significant step by acquiring full ownership and initiating a C$200 million modernization project.
• This ambitious investment will replace all electrolytic cells and overhead cranes, enhancing energy efficiency, productivity, and workplace safety.
• Set for completion in 2025, this project solidifies CEZinc’s role in both the Canadian and global zinc supply chain.

General Smelting of Canada – Expertise in lead alloy production

Founded in 1955 and based in Lachine, Quebec, General Smelting of Canada has established itself as a leader in producing lead alloys and products for a vast array of applications—from metal refining to automotive batteries.

Today, they specialize in crafting lead alloy anodes for zinc, copper, cobalt, and nickel refining processes, as well as anodes for chrome plating. Additionally, General Smelting manufactures lead sheets, which are ideal for radiation shielding and soundproofing.

Kidd Operations – A legacy of base metal mining

Located in Timmins, Ontario, Kidd Operations is home to the deepest base metal mine below sea level in the world. For nearly 60 years, it has supplied copper, zinc, and silver to global markets.

• Due to ore depletion and operational considerations, Kidd Mine will close by the end of 2026.

• Site reclamation will begin in 2027, guided by environmental and regulatory standards.

• We are working closely with employees, Indigenous partners, and local stakeholders to ensure a responsible and transparent transition.

Despite the impending closure, our team’s unwavering dedication to safety has been recognized with the prestigious 2024 John T. Ryan Regional Award for the best safety performance in Ontario. This commitment was further demonstrated when they secured the top award at the Ontario Mine Rescue competition in June 2025.

In Ontario, every underground mine is mandated to maintain a mine rescue program, and Ontario Mine Rescue, under the authority of the Occupational Health and Safety Act, ensures mines are equipped with adequate emergency response capabilities.

Global demand for zinc is projected to rise in the coming decades. This trend is fuelled by a growing population and rising living standards in developing countries, along with evolving consumption patterns in an increasingly environmentally conscious economy.

As global demand for zinc and lead continues to rise, we remain committed to responsibly delivering it while helping support Canada’s economy and advancing everyday life.
