“The top 5 cobalt mining companies are projected to supply over 60% of global cobalt output in 2025.”

Overview of Cobalt’s Importance in 2025

Cobalt remains one of the most critical minerals in the global supply chain for 2025, underpinning the rapid evolution of batteries, clean energy technologies, electric vehicles, and aerospace applications. Its unique combination of high energy density, thermal stability, and corrosion resistance renders it indispensable for manufacturing not only cutting-edge batteries but also emerging superalloys and specialized electronic components.

Beyond technology, cobalt’s role in agriculture and infrastructure has broadened in recent years. As a vital micronutrient in fertilizers, cobalt significantly improves livestock health and enhances soil quality.

2025’s surging demand, driven primarily by the electrification of transport, expansion of renewable energy, and the ongoing digital revolution, has cemented cobalt’s position as one of the world’s most sought-after minerals. Understanding the biggest cobalt companies, mining operations, and their impact on the global production landscape is essential for stakeholders in industries as diverse as agriculture, infrastructure, defence, and technology.

Comparative Ranking Table of Top Cobalt Mining Companies & Mines, 2025

The following table provides a ranking of the biggest cobalt mining companies and their flagship mines for 2025, along with estimated production stats, key global sites, and notable industry trends.

Biggest Cobalt Mining Companies in 2025: Industry Landscape & Key Players

The biggest cobalt mining companies in 2025 continue to exert a significant influence on the global supply chain, shaping industry trends, ethical and environmental standards, and technology adoption. In 2025, the world’s cobalt production is still dominated by companies operating in the Katanga region of the Democratic Republic of Congo (DRC), which accounts for over half of all cobalt supplies worldwide.

1. Glencore plc: DRC’s Leader in Cobalt Mining

Glencore plc, headquartered in Switzerland, remains the industry leader in global cobalt production. Its flagship Mutanda and Katanga mines—both located in the mineral-rich heart of the DRC—are notable among the world’s largest cobalt mines.

• Glencore’s integrated commodity trading business and digital supply chain management ensure efficient extraction and rapid delivery across borders.
• The company is at the forefront of ESG (Environmental, Social, Governance) initiatives, investing heavily in traceability and sustainable mining practices.
• Challenges in DRC’s artisanal mining sector—including ethical sourcing and community relations—have driven Glencore to enforce rigorous due diligence at its operations, positioning itself as a responsible industry steward.

2. China Molybdenum Co., Ltd. (CMOC): Integrating Extraction & Processing

China Molybdenum Co., Ltd. (CMOC) is consolidating its role as a top global cobalt producer through the Tenke Fungurume mine in the DRC. As the battery and electronic manufacturing hub of China thrives, CMOC’s vertically integrated operations allow:

• Direct linking of mineral extraction with industrial processing and infrastructure development in China and beyond.
• Efficient infrastructure and modern logistics, reducing supply disruptions and feeding Asia’s soaring battery and EV demand.
• A strong commitment to expanding processing capabilities and upholding internationally recognized sustainability standards.

3. Huayou Cobalt Co., Ltd.: Supply Chain Transparency and Processing Excellence

Huayou Cobalt Co., Ltd. is unique among the biggest cobalt companies for its dual role as a refining company and producer, operating several logistics hubs and mining sites in Africa, primarily DRC and Zambia. In 2025, Huayou is making waves for:

• Early implementation of blockchain-based supply chain transparency solutions, ensuring conflict-free sourcing for corporate clients.
• Adopting product traceability systems—essential for companies and governments requiring proof of ethical and sustainable mining practices.
• Investments in processing technology and refining expansion to support the surging demand for batteries and electronics.

4. Eurasian Resources Group (ERG): Sustainable Extraction from Tailings

Eurasian Resources Group (ERG) stands out by operating Metalkol RTR, an advanced extraction project leveraging historical mine tailings in the DRC. Their innovative approach in 2025 includes:

• Extracting cobalt from previously mined materials, significantly reducing the environmental impact associated with traditional open-pit mining.
• Supporting a circular economy within the mining sector by reclaiming lost resources and offsetting carbon footprints.
• Focusing on sustainable, low-impact operations, aligning with both international standards and community expectations.

5. Emerging Global Players & Diversification Initiatives

While the DRC remains the epicenter for cobalt production, stakeholders worldwide are investing in supply chain diversification efforts. The emergence of companies like:

• First Cobalt (Electra Battery Materials) in Canada, leading North American supply and recycling initiatives,
• Jinchuan Group in China, expanding refining capacity and digital mining technologies,

represents a broader trend towards reducing geopolitical risk and fostering responsible sourcing outside traditional mining hotspots.

“Cobalt production is expected to increase by 8% in 2025, driven by electric vehicle battery demand.”

Biggest Cobalt Mine in 2025: Tenke Fungurume’s Global Impact

Among the biggest cobalt mining sites worldwide, the Tenke Fungurume mine—operated by CMOC—stands as the largest cobalt mine by output in 2025. Located in the mineral-rich Katanga region of the DRC, Tenke Fungurume is renowned for its:

• Massive Production Volume: Regularly accounting for nearly one-fifth of global cobalt output each year.
• Integrated Cobalt-Copper Operations: Allowing simultaneous extraction of two critical minerals for battery and technology manufacturing.
• State-of-the-Art Infrastructure: Continuous investment in automation, resource efficiency, and community engagement has set new benchmarks for mining operations in the region.

Modernization and digitalization at Tenke Fungurume exemplify how the cobalt sector is addressing both supply chain resilience and environmental stewardship in 2025.

Environmental & Ethical Challenges in Cobalt’s Supply Chain

With intense global scrutiny on sourcing and transparency, the cobalt sector in 2025 faces multifaceted challenges:
1. Artisanal Mining and Human Rights: Artisanal mining in the DRC has historically faced criticism for child labor, unsafe conditions, and lack of oversight. In response, the biggest cobalt mining companies are:

• Partnering with NGOs and audit firms for rigorous on-site inspections.
• Integrating blockchain-based traceability into their supply chains to guarantee conflict-free cobalt for industries worldwide.

2. Environmental Management and Community Impact: Cobalt extraction traditionally exerts a heavy environmental toll—soil degradation, water contamination, and elevated carbon emissions.

• In 2025, leading companies are adopting AI-driven and satellite-based monitoring tools to measure, report, and reduce negative impacts. For instance, Farmonaut offers businesses carbon footprint monitoring technology to quantify emissions and track resource use.
• Resource-efficient tailings management and reclamation projects are slowly becoming industry norms.

3. Supply Chain Diversification and Security: The global sector’s continued dependence on the DRC has led manufacturers—particularly in electric vehicles and clean energy technologies—to actively source from alternative regions like Australia, Canada, and the US, though these currently contribute only a fraction of global output.

The relentless focus on responsible sourcing and environmental stewardship is strengthening not just the sustainability profile of biggest cobalt companies but also the overall resilience of the global mineral supply chain.
