Key Takeaways:
(P1) South Korea’s POSCO International and U.S.-based ReElement Technologies are investing $200 million to build an integrated rare earth refining and magnet production complex in the United States, a direct challenge to China’s long-standing dominance in the critical minerals sector.
(P2) "This joint venture represents a defining moment in the evolution of the rare earth supply chain in the United States," Mark Jensen, Chief Executive Officer of ReElement Technologies, said in a statement. "By combining ReElement's refining-first platform with POSCO International's global capabilities and industrial scale, we are creating a fully integrated, end-to-end solution."
(P3) The project will be developed in phases, initially targeting an annual production of approximately 3,000 metric tons of separated rare earth oxides by 2028, before expanding to 6,000 tons by 2030. The facility will produce neodymium-praseodymium (NdPr) oxide, a key material for permanent magnets, along with essential heavy rare earth oxides like dysprosium and terbium.
(P4) The venture strikes at a major strategic vulnerability for Western nations, as China currently accounts for 92 percent of global rare earth magnet production and is the sole producer of heavy rare earths like dysprosium, according to the Korea International Trade Association. With site selection for the new U.S. facility underway, the project’s pilot production is slated to begin in late 2027.
The U.S.-South Korea partnership aims to create a resilient, allied supply chain for minerals crucial to high-growth sectors including electric vehicles, advanced semiconductors, and defense systems. By onshoring the entire process from feedstock refining to magnet manufacturing, the joint venture seeks to mitigate the geopolitical risks associated with the current concentration of production in China.
POSCO International, which will hold a controlling stake and oversee management, brings its global supply chain network, while ReElement provides its proprietary refining technology. ReElement’s water-based ion chromatography process is considered a more environmentally friendly and simpler alternative to the solvent-heavy methods traditionally used in China.
The total $200 million investment will be deployed in two stages. An initial $100 million will fund the construction of the first phase and initial operating expenses. A second $100 million is allocated for the phase-two expansion and the eventual build-out of permanent magnet manufacturing capabilities, contingent on market conditions. The partners are also establishing a joint task force to secure both domestic and international feedstock from primary and recycled sources.
