The US supports South Africa’s Phalaborwa Rare Earth Project, funded with $50 million in equity investment from the U.S. International Development Finance Corporation (DFC), which will extract rare earth elements from approximately 35 million tons of phosphogypsum waste produced during fertilizer manufacturing. The International Energy Agency (IEA) predicts that global demand for rare earth will increase threefold by 2030 and that China currently produces 60-70% of the global supply, making projects like the Phalaborwa Rare Earths project strategically necessary to diversify supply sources and develop technological independence.

What Is the Phalaborwa Rare Earth Project?

US supports South Africa’s Phalaborwa Rare Earth Project, a unique mining project developed by Rainbow Rare Earths in collaboration with TechMet. Unlike regular mining, where rare earths are mined from the soil, Phalaborwa uses an advanced technique of mining rare earth elements from industrial waste material, thus being cost-effective and eco-friendly.

Key minerals include:

• Neodymium and praseodymium (used in permanent magnets)
• Dysprosium and terbium (important for high-temperature applications)

They find applications in electric cars, windmills, robotics, and military hardware.

Why Is the US Supporting This Project Despite Diplomatic Tensions?

The US supports South Africa’s Phalaborwa Rare Earth Project despite difficulties stemming from the Trump Administration and strained relations between the US and South Africa; energy for growth remains a priority. The grant that was approved in 2023 can be viewed as being part of a larger international strategy to decrease the world’s dependence on China’s processing of critical minerals.

The DFC, established during Trump’s earlier administration, approved the investment in 2023 under Joe Biden, and the current administration has chosen to proceed, demonstrating an across-the-board agreement upon securing infrastructure to support supply chains for critical minerals.

How Does the Project Operate, and What Makes It Unique?

In contrast to traditional mining, the Phalaborwa Rare Earth Project employs an above-ground extraction technique on pre-prepared waste. The benefits include:

• Low operation costs (no need for extensive drilling and crushing)
• Minimal impact on the environment
• 90% use of renewable energy

As stated by the project’s director, Alberto Bruttomesso, the waste material has already undergone highly energy-intensive processes.

What Makes Rare Earths So Important?

While the term implies rarity, in actuality, rare earths are neither rare nor easy to mine. These elements are vital for producing the following products:

• Electric cars
• Windmills
• Smartphones and other electronic devices
• Military equipment

The demand for critical minerals, such as lithium, cobalt, and rare earth elements, is expected to grow by 500% by 2050, says the World Bank.

Can This Project Compete with China?

China continues to lead in rare earth production. Nonetheless, Phalaborwa and similar projects are vital in creating alternative production lines, mitigating geopolitical risks, and stimulating innovation in mineral extraction processes.

According to Neha Mukherjee of Benchmark Mineral Intelligence, although the project is very promising, its full potential is yet to be realized since it is still in an experimental phase.

Nonetheless, its low cost makes it a formidable competitor.

What Is Africa’s Position in the Global Minerals Strategy?

Africa is becoming a major player in the production of critical minerals. America is expanding its presence by:

• Investing in rare earth deposits in Mozambique
• Developing infrastructure such as the Lobito Corridor Railway

China continues to dominate investment in mining in Africa. The Nordic Africa Institute says that the USA is attempting to “catch up” in this sector.

What Are the Risks and Challenges Ahead?

There is uncertainty around scaling up from pilot projects using new waste-to-resource technology to fully operational production facilities. The processing of rare earths is chemically very complex; even minor inefficiencies in the production process may have significant effects upon output and the cost per unit.

The project’s ability to meet its 2028 production target will hinge on securing the necessary regulatory approvals, whether the required infrastructure exists to support operations in Phalaborwa, and whether investors remain confident in it as an ongoing business entity.

A Strategic Move Toward Mineral Independence

The US supports South Africa’s Phalaborwa Rare Earth Project, one that incorporates elements of both technological advancement and geopolitics into its plans. By converting mining by-products into commercial materials, this project epitomizes the principle of using innovation to address both the planet’s environmental problems and its economic challenges.

With global demand for rare earths continuing to rise exponentially, projects like this one will undoubtedly impact how future generations utilize renewable energy resources, how our respective national defense capabilities operate, and how cutting-edge technology is developed.
