Posco International and ReElement Technologies Corporation will build a U.S. rare earth refining facility reducing China dependence.
Posco International, a South Korean trading and energy company, has partnered with U.S.-based ReElement Technologies Corporation to construct a $200 million rare earth separation and refining facility in the United States. The joint venture aims to establish a secure and diversified supply chain for critical minerals, reducing global reliance on China, which currently dominates the rare earth market.
The agreement, signed in Washington, D.C., will see the two companies build a rare earth separation and refining plant with an initial annual production capacity of 6,000 tons. Posco will hold a controlling stake and manage the joint venture, while ReElement Technologies will contribute its core refining technology. The partnership also envisions the eventual development of an integrated production complex capable of manufacturing permanent magnets, which are essential components in electric vehicles (EVs), robots, and artificial intelligence (AI) data centers. This move is particularly significant given China's near-monopoly on the production of powerful industrial magnets made from neodymium, accounting for 92% of the world's supply, and its complete control over heavy rare earths like dysprosium.
This collaboration is part of a broader industrial cooperation effort between South Korea and the United States to bolster critical technology supply chains and enhance national security. The U.S. Department of Commerce has designated rare earth elements as critical materials, necessitating domestic supply chain resilience under the Defense Production Act Title I program, which may offer regulatory and financial support for such infrastructure. The $200 million investment represents one of the largest disclosed U.S. rare earth refining infrastructure investments in the current market cycle, providing substantial capital for market penetration.
Economically, the project signifies a significant investment in U.S. manufacturing and job creation, supporting the domestic production of materials crucial for advanced industries. Geopolitically, it aims to mitigate supply chain vulnerabilities and reduce the strategic risk associated with China's dominance in rare earth processing, which accounts for approximately 70% of global capacity. The partnership also strengthens economic ties between the U.S. and South Korea, aligning with both nations' strategies to secure critical mineral resources. Industry-specific impacts include a bolstered supply chain for the rapidly expanding EV and defense sectors, fostering greater competition and resilience in the rare earth market. ReElement's Marion, Indiana facility is expected to reach an initial capacity exceeding 10,000 metric tons per annum of refined minerals, processing both virgin and recycled feedstocks. This initiative marks a potential turning point in establishing Western-controlled rare earth refining capacity and offers a blueprint for future international collaborations among allied nations facing similar supply vulnerabilities.
