These elements possess unique magnetic, luminescent, and catalytic properties, making them indispensable in various industries. Here's a quick rundown of why they're so crucial:

• Electronics: REEs are used in smartphones, computers, and televisions to create vibrant displays and efficient components.
• Renewable Energy: They're vital for manufacturing wind turbines and electric vehicle motors, contributing to a greener future.
• Defense: REEs are critical in defense applications, including missile guidance systems, radar, and communication equipment.
• Healthcare: They're used in medical imaging, lasers, and cancer treatments, enhancing diagnostic and therapeutic capabilities.

Because of their wide range of applications and unique properties, rare earth elements have become essential for modern technological advancement and economic growth. Now that we know what they are and why they matter, let's look at the rare earth situation in the US.

US Rare Earth Reserves: Untapped Potential

So, how much rare earth does the US have? The United States Geological Survey (USGS) estimates that the US has significant reserves of rare earth elements. Although the exact figures fluctuate with new discoveries and assessments, the reserves are substantial enough to potentially meet a significant portion of domestic demand. According to the USGS, the US possesses an estimated 1.5 million metric tons of rare earth oxide reserves. This places the US among the countries with the largest reserves globally.

However, having reserves is one thing; producing them is another. Historically, the US was a leading producer of rare earth elements. The Mountain Pass mine in California was once a major global supplier. However, production declined in the late 20th century due to environmental regulations and competition from other countries, particularly China.

Despite the past decline, there's renewed interest and investment in domestic rare earth production. The US government recognizes the strategic importance of securing a stable supply chain for these critical elements. Efforts are underway to revitalize existing mines and develop new projects. The goal is to reduce reliance on foreign sources and boost domestic production capabilities.

Some promising rare earth projects in the US include:

• Mountain Pass Mine (California): This mine is currently the only active rare earth mine in the US and is undergoing expansion to increase production capacity.
• Bear Lodge Project (Wyoming): This project is exploring the development of a rare earth mine and processing facility in northeastern Wyoming.
• Round Top Project (Texas): Located in West Texas, this project aims to extract rare earth elements and other critical minerals from a unique geological deposit.

These projects represent significant steps toward enhancing domestic rare earth production and reducing dependence on foreign suppliers. As these initiatives progress, the US could regain its position as a major player in the global rare earth market.

Current Rare Earth Production in the US

Currently, the Mountain Pass mine in California stands as the only active rare earth mine in the United States. Operated by MP Materials, the mine has been ramping up production in recent years. In 2023, the US produced approximately 43,000 metric tons of rare earth oxides, according to the USGS. This figure represents a significant increase compared to previous years, signaling a resurgence in domestic production capabilities.

However, it's important to note that while the US is increasing its rare earth mining output, a significant portion of the extracted materials is still shipped to China for processing. China possesses advanced processing technologies and infrastructure, making it a dominant player in the rare earth refining industry. This reliance on foreign processing raises concerns about supply chain security and the need to develop domestic processing capabilities.

To address this issue, there are ongoing efforts to establish rare earth processing facilities within the US. These initiatives aim to create a vertically integrated supply chain, from mining to refining, ensuring a more secure and resilient domestic industry. The development of these facilities is crucial for reducing dependence on foreign sources and maximizing the economic benefits of domestic rare earth production.

Several companies are investing in rare earth processing technologies and facilities in the US. These investments include:

• MP Materials: The company is building a rare earth processing facility at the Mountain Pass mine to refine rare earth concentrates into separated rare earth oxides.
• USA Rare Earth: This company is developing a rare earth processing plant in Stillwater, Oklahoma, to produce high-purity rare earth oxides and other critical minerals.
• Lynas Rare Earths: An Australian company, Lynas is constructing a rare earth processing facility in Texas to process rare earth materials from its mine in Western Australia.

These investments represent significant progress toward establishing a complete domestic rare earth supply chain. As these facilities come online, the US will be better positioned to meet its rare earth needs and reduce reliance on foreign sources.
