Building a supply chain for rare earth elements

Rare earth elements (REEs) are essential ingredients in electric vehicles, wind turbines, and many electronics. As with most critical minerals, China controls the vast majority of the REE supply chain. And so when it banned the export of REE processing technology last December, it raised concerns ab

Topics Discussed

Episode Summary

Executive Summary: This episode explains why rare earth elements—especially magnet materials like neodymium and dysprosium—are essential to the energy transition, why China dominates their supply chain, and how Cyclic Materials aims to reduce dependence through recycling. The discussion covers the full rare earth value chain, substitution limits, Western supply-chain buildout, and the advantages of recycling magnet feedstock over virgin mining.

Main Topics: What rare earth elements are and why they matter (Priority: 5/5): Ahmad Garaman defines rare earths as 17 elements with unique chemical and physical properties that enable high-performance applications, especially permanent magnets used in EVs and wind turbines. Why permanent magnets dominate value in the rare earth market (Priority: 5/5): The conversation breaks down the 17 elements into magnet-relevant materials, emphasizing that a small subset drives most of the market’s value and is central to electrification. Rare earth supply chain and China’s dominance (Priority: 5/5): The episode traces the path from ore to concentrate to mixed oxides to metals and magnets, showing how China controls most processing and magnet manufacturing even when mining occurs elsewhere. Geopolitics and export controls (Priority: 4/5): Shail and Ahmad discuss China’s export pause on rare earth extraction, processing, and recycling technologies, plus Western efforts such as IRA-related investments and DoD funding to rebuild capacity. Substitution and rare-earth-free magnets (Priority: 4/5): They examine whether magnets can be redesigned to reduce or eliminate rare earths, noting that alternatives exist but are not yet suitable for the most demanding EV and wind applications. Cyclic Materials’ recycling model (Priority: 5/5): Ahmad explains Cyclic’s hub-and-spoke approach: separate magnets from end-of-life products at local spokes, then process magnets at a central hub into mixed rare earth oxides. Recycling’s role versus mining (Priority: 4/5): The discussion concludes that recycling can meaningfully reduce pressure on virgin mining, but cannot fully replace it given rising demand; both are needed for a secure supply chain.

Key Arguments: Rare earth elements are distinct from lithium and cobalt; they are a group of 17 metals whose magnetic and thermal properties make them uniquely valuable for electrification. Only a subset of rare earths—especially neodymium, praseodymium, dysprosium, terbium, and samarium—drives most permanent magnet demand and value. Permanent magnets are critical because they enable efficient conversion between electrical and mechanical energy in EV motors and wind turbine generators. China dominates the rare earth chain not just in processing and magnet manufacturing, but also in mining, due to historical investment, environmental burdens, and strategic industrial policy. Rare earth processing is complex and waste-intensive because the elements have very similar chemistry, requiring long solvent extraction chains. Rare earth-free magnets exist, but current alternatives do not yet meet the performance needs of high-temperature, high-efficiency applications like EV traction motors. North American and European efforts are improving mining, refining, and magnet manufacturing capacity outside China, which could reduce buyer risk over time. Rare earth recycling is underdeveloped because magnets are lost into steel recycling streams and end up in slag, where recovery is technically and economically unattractive. Cyclic’s method captures magnets before they are lost downstream, yielding a higher-quality feedstock than mining because it concentrates only the valuable magnet elements. Recycling is complementary to mining: it lowers carbon and water use and can reduce supply pressure, but growing demand means primary production will still be necessary.

Data Points: Number of rare earth elements: 17 - Ahmad describes rare earths as 15 plus 2 elements at the bottom of the periodic table. Share of rare earth volume used in magnets: About 40% - Five or six magnet rare earths account for roughly 40% of rare earth volumes. Share of rare earth dollar value used in magnets: Over 95% - Most market value comes from the permanent magnet subset. China’s share of rare earth mining: About 60% - Majority of rare earth mining happens in China. China’s share of rare earth processing: Over 90% - Most concentrates are processed in China. China’s share of magnet manufacturing: Over 95% - Magnet production is overwhelmingly concentrated in China. Rare earth recycling rate globally: Less than 1% - Rare earths are among the least circular metals. Rare earth market size: About $20 billion in 2024 - Shail notes the current size of the rare earth market. Mixed rare oxide composition from California material: About 70-80% lanthanum and cerium oxide - Example given for ore shipped from California to China, illustrating low-value content in mixed oxides. Potential recycling rate for rare earths: Around 40-50% - Ahmad suggests rare earths could eventually be recycled at rates similar to other metals. Cyclic Materials target recycling share by 2030-2032: Around 2% of world rare earths - Company ambition for near-term scaling. DoD funding for Lynas Texas refining: Over $200 million - Example of U.S. government support to build ex-China refining capacity. DoD funding for Vacuum Schmitz magnet manufacturing: Over $100 million - Support for North American magnet production capacity.

Pivotal Quotes: "The energy transition is, at least to a first order, basically a transition from fossil fuels to metals and minerals." — Shail Khan: Opening framing for why critical minerals, including rare earths, are central to decarbonization. "We don't recycle much of those at all today... because magnets being magnetic attach to steel and travel with steel into steel recycling plants." — Ahmad Garaman: Explanation of why rare earth recycling is so low in current waste streams. "Engineers will still really like rare magnets, and buyers also will like rare magnets because they have multiple options for sourcing of rare magnets now." — Ahmad Garaman: Optimism that ex-China supply buildout will preserve technical benefits while reducing supply-chain risk.

Implications: Rare earth demand will keep rising with EVs and wind, so the industry must diversify supply, expand Western processing, and scale recycling. Cyclic’s approach could improve resilience, cut emissions, and reduce dependence on China, but it will complement—not replace—mining.
