Rare Earth Elements: Brazil’s Hidden Treasure That Could Transform the Nation’s Wealth

(Analysis) Brazil stands on the cusp of an economic revolution, thanks to its vast reserves of rare earth elements (REEs).

These critical minerals power modern technology and could potentially position the country as one of the world’s wealthiest nations. With strategic development of these resources, Brazil could emerge as a global powerhouse in the high-tech materials sector.

Historical Context and Current Position

Brazil’s relationship with rare earth elements dates back to 1885, when the extraction of monazite sand began in the Prado region of Bahia. For decades, Brazil, alongside India, led the world market until the mid-1950s, when they were eventually overtaken by producers like South Africa that modernized their operations.

Today, Brazil holds the third-largest rare earth reserves globally, with approximately 22 million tonnes primarily distributed across the states of Minas Gerais, Bahia, Goiás, and São Paulo.

This positions the country as a significant player alongside China (which currently dominates more than 80% of the global market) and Vietnam.

Despite these vast resources, Brazil’s current production remains limited, with estimates ranging from 80 to 2,000 tonnes annually, a fraction of the global supply of approximately 300,000 tonnes.

Key Brazilian Rare Earth Regions:

• Araxá, Minas Gerais
• Morro do Ferro, Minas Gerais
• Poços de Caldas, Minas Gerais
• Minaçu, Goiás
• Catalão, Goiás
• Various locations in Bahia and São Paulo

Recent Developments and Major Projects

Brazil has recently accelerated its efforts to develop its rare earth industry. The Serra Verde project in Goiás became Brazil’s first integrated ionic absorption clay rare earths mine and processing operation to commence production earlier this year.

When fully operational, the project aims to produce approximately 5,000 tonnes of rare earth oxide concentrates annually, focusing on critical elements like neodymium, praseodymium, dysprosium, and terbium.

Several other significant projects are underway:

• Carina Project: Located in Goiás state, this is currently Brazil’s most heavily invested rare earth project. It has a projected lifespan of 22 years with an annual production capacity of 191 tonnes of dysprosium and terbium and 1,350 tonnes of praseodymium-neodymium. Production is expected to commence in 2028.
• Caldeira Project: Led by Australian mining company Meteoric Resources in Minas Gerais, this project recently attracted interest from the U.S. Export-Import Bank with anticipated financing of approximately $250 million.
• Poços de Caldas Project: With planned investments of R$1.5 billion, this initiative (sometimes called the “Boiler Project”) promises to create hundreds of direct jobs and thousands of indirect opportunities.
• Colossus Project: Developed by Australian company Viridis Mining & Minerals in Minas Gerais.
• MoCa Project: A Brazil-Germany joint venture focused on extracting rare earths from mining residues at the Catalão site in Goiás.

Investment and Economic Impact

The Brazilian Mining Association (Ibram) estimates that investments in rare earth projects in the country are expected to increase dramatically to $1.46 billion during 2024-28, compared to only $150 million during 2023-27. However, this still represents a small fraction of the projected $64.5 billion in total mining investments expected in Brazil by 2028.

The economic potential is staggering when considering the value of these minerals. Neodymium oxide, for example, can fetch up to US$75,000 per ton, compared to iron ore at approximately US$120 per ton—making it 625 times more profitable.

This vast difference in value could potentially transform Brazil’s economic landscape, reducing dependency on traditional commodities and diversifying the nation’s export portfolio.

Strategic Importance of Rare Earth Elements

Rare earth elements are indispensable components in numerous advanced technologies:

• High-performance magnets for electric vehicle motors
• Wind turbine generators and other renewable energy technologies
• Electronic devices including smartphones, computers, and televisions
• Catalysts for petroleum refining and chemical production
• Laser technologies and medical equipment
• Defense technologies including guidance systems and radar

Despite their name, rare earth elements are not necessarily scarce in the Earth’s crust. However, they typically appear in low concentrations that make extraction economically challenging. What makes Brazil’s deposits particularly valuable is their relatively high concentration levels, making exploitation more viable.

Challenges and Market Conditions

Despite the promising outlook, Brazil faces significant challenges in developing its rare earth industry:

Market Volatility: The rare earth market has experienced significant price fluctuations, with prices declining approximately 70% over the past two years. This volatility creates uncertainty for long-term investment planning.

Technical Expertise: Extracting and processing rare earths requires sophisticated technology and expertise that Brazil is still developing.

Environmental Concerns: Mining operations can generate environmental contamination if not properly managed. Brazilian regulations require concession holders to restore areas degraded by mining activities.

Global Competition: While China currently dominates the market, other countries are also racing to develop their rare earth resources, creating a competitive global landscape.

Brazil does possess competitive advantages, including relatively low operational costs compared to competitors in Australia or North America. These advantages could help maintain profitability even during market downturns.

Sustainable Development and Environmental Considerations

One of the main principles of the Mineral Law in Brazil is environmentally sustainable mining. Companies are increasingly incorporating sustainable practices not only for mine closure but throughout their operations. This approach aligns with global expectations for responsible resource extraction.

For the Catalão site, researchers are investigating the extraction of rare earths from mining residues, which could offer environmental advantages compared to conventional extraction from primary materials. This innovative approach could position Brazil as a leader in sustainable rare earth production.

Brazil’s Opportunity for Global Leadership

With strategic investments and a balanced approach to economic development and environmental protection, Brazil has the potential to reshape the global rare earth supply chain. This would have significant geopolitical implications, reducing global dependence on China and strengthening Brazil’s international standing.

The Brazilian government, in partnership with private companies and international collaborators, is working to develop the necessary infrastructure, technology, and expertise to fully capitalize on this opportunity. By focusing on both extraction and value-added processing, Brazil could maximize the economic benefits of its rare earth resources.

Looking Ahead

The future of Brazil’s rare earth industry appears promising, but realizing its full potential will require continued investment, technological innovation, and strategic planning. As the world increasingly transitions to clean energy and advanced technologies, the demand for rare earth elements will likely continue to grow.

By developing its rare earth resources in a sustainable and strategic manner, Brazil has an unprecedented opportunity to transform its economy. This could enable the country to emerge as a critical player in the global technology supply chain.

The rare earth treasure beneath Brazilian soil could indeed make the country one of the wealthiest nations in the coming decades. It also has the potential to make Brazil one of the most strategically important nations.
