The Power of Rare Earth Elements: Technology’s Hidden Gems


Rare Earth Elements (REEs), often referred to as the “seeds of technology,” play an extraordinary role in shaping our modern world. From powering our smartphones to driving innovations in green technology and supporting vital defense systems, REEs are the unsung heroes behind the scenes. In this comprehensive guide, we will delve into the world of these remarkable elements and uncover their importance, sources, and the ongoing efforts to secure a stable supply chain in the United States.

What Are Rare Earth Elements?

Rare Earth Elements (REEs), a group of seventeen metallic elements, are the backbone of modern technology. These elements, found on the periodic table, consist of fifteen lanthanides—elements with atomic numbers 57 to 71, from lanthanum to lutetium—along with scandium and yttrium. Scandium and yttrium are often considered REEs due to their similar chemical properties, high melting points, and malleability.

Each of the lanthanides contains a subshell that houses f-electrons, giving them their magnetic and luminescent properties. It’s these unique properties that make REEs so vital to various applications, from electronics to green energy.

The Significance of Rare Earth Elements:

Rare Earth Elements are the unsung heroes of modern technology. These elements enhance the performance of other materials while allowing for miniaturization and optimization. Everyday technologies, such as smartphones and computers, heavily rely on them. Moreover, they are vital in advanced medical equipment like MRIs, laser scalpels, and even some cancer drugs.

In the realm of defense applications, REEs are the backbone of critical systems. Satellite communications, guidance systems for missiles, and precision-guided weapons all depend on the unique properties of these elements. Without them, our defense systems would be far less effective.

Unveiling the Origins of REEs:

Although REEs are not genuinely rare, their extraction and processing pose significant challenges. These elements are dispersed throughout the Earth’s crust, making economically exploitable ore deposits sparse. The historical connection between REEs and uranium mining is noteworthy. Initially, they were recovered as a byproduct during the process of mining and recovering uranium.

The 1960s marked a turning point for REEs, as the adoption of color television resulted in the first significant commercial use of these elements. Most REEs were mined in California during this period. However, the processes for extracting REEs were labor-intensive and environmentally damaging, which ultimately paved the way for China’s dominance in the 1990s.

China’s Dominance in REE Production:

China’s ascent to become the world’s dominant producer of REEs in the 1990s had far-reaching consequences. The nation’s lower labor costs and more relaxed environmental regulations allowed it to outcompete other nations. By 2000, China controlled over 95% of the world’s REE mining, creating a staggering monopoly with significant global implications.

This monopoly became glaringly evident in 2010 when a territorial conflict between China and Japan resulted in China embargoing the sale of REEs to Japan. The repercussions were immediate and widespread, highlighting the vulnerability of nations dependent on China for their emerging technologies. It was a wake-up call for the world to reevaluate the security of its supply chain.

The Perils of Dependency:

China’s stranglehold on REE production underscored the perilous nature of such dependency. It revealed the potential for geopolitical tensions to disrupt the supply of these critical elements. The consequences of such disruptions can be dire, impacting industries ranging from consumer electronics to defense.

Recognizing the strategic vulnerability, several U.S. administrations have identified the need to diversify the REE supply chain as a critical national concern. Efforts to reduce dependency on a single supplier and secure a stable source of REEs have gained momentum.

Diversifying REE Sources:

In recent years, there has been a concerted effort to diversify the sources of REEs, with the aim of reducing dependence on China. Approximately 35% of REE minerals in 2022 were being mined outside of China, representing a significant step towards supply chain resilience. However, this diversification has not extended uniformly throughout the entire supply chain.

A majority of REEs mined in other countries are still sent to China for separation, refining, and magnet production. This underscores the need for comprehensive strategies to ensure a fully diversified and secure supply chain.

Addressing the Vulnerability:

The U.S. government has recognized the economic, security, and environmental risks associated with a lack of secure access to critical minerals, including REEs. To bolster domestic supply chains and reduce vulnerability, Congress has allocated over $800 million for research and development in this critical area.

Initiatives encompass sourcing through mining or recycling, developing innovative separation and recovery technologies, and increasing efficiency in existing applications to reduce demand growth. These initiatives aim to safeguard national interests and ensure a reliable supply of REEs for years to come.

Paving the Way Forward:

In support of building robust and secure supply chains for REEs, Rare Element Resources has received a commitment from the Department of Energy for approximately $22 million. This funding represents 50% of the total anticipated cost for the development of a demonstration-scale plant. The plant, expected to receive final permits in the summer of 2023, aims to confirm the commercial viability of the company’s innovative separation and recovery technology.

This investment represents a critical step toward achieving a secure, long-term source of REEs critical to our high-tech world. It exemplifies the collaborative efforts of government, industry, and research institutions in addressing the challenges associated with REE supply chains.

The Role of Rare Earth Elements in Green Technology:

One of the most promising and critical aspects of rare earth elements lies in their contribution to green technology. As the world strives to achieve net-zero carbon emissions and combat climate change, REEs are playing a pivotal role. Wind turbines, which are a cornerstone of renewable energy, rely on the unique properties of REEs to generate electricity efficiently. The magnets in these turbines, often containing neodymium and dysprosium, help convert wind energy into electrical power.

Electric vehicles (EVs) are another area where REEs shine. The electric motors in EVs use powerful permanent magnets, and neodymium magnets are the go-to choice. These magnets are not only strong but also lightweight, a crucial factor in ensuring the efficiency and range of electric vehicles. As the world shifts toward EVs as a sustainable transportation solution, the demand for REEs in this sector continues to grow.

Rare Earth Elements in National Security:

Ensuring national security is of utmost importance for every nation. Rare earth elements have emerged as a key player in ensuring a nation’s security, particularly in the realm of defense technology. Radar and sonar systems, which are critical for monitoring airspace and maritime activities, rely on REEs to function effectively. The unique magnetic properties of certain REEs, such as gadolinium and samarium, enhance the precision and sensitivity of these systems.

Furthermore, guidance systems in missiles and precision-guided weapons heavily depend on REEs for their performance. These systems require stable and reliable components, and REEs provide the necessary materials to achieve this. In times of conflict or geopolitical tension, having a secure supply of REEs is essential for maintaining a nation’s defense capabilities.

Rare Earth Elements and Emerging Technologies:

The world of technology is in a constant state of evolution, and REEs are at the forefront of many emerging innovations. Quantum computing, for example, holds the promise of revolutionizing computation, and some REEs are vital for creating the necessary hardware.
