Breaking China's rare-earth processing dominance requires building capacity at every stage below the mine: crushing and beneficiation, solvent extraction to separate individual elements (a 100+ stage chemical cascade for heavy rare earths), reduction to metals, alloying, and finally magnet sintering. Each stage has its own capital requirements, environmental challenges, and workforce needs.
Non-China projects are emerging but remain small. Lynas Rare Earths operates a separation plant in Malaysia with a capacity of roughly 10,500 tons REO per year and is expanding in Australia. MP Materials in the United States is developing a processing facility in Texas alongside its Mountain Pass mine. In India, the India–U.S. critical minerals deal signed in 2025 aims to accelerate joint processing ventures. But disclosed non-China separation project capacities collectively amount to a few tens of thousands of tons per year, set against China's processing throughput exceeding 200,000 tons per year. The gap is an order of magnitude.
The timeline matters. Even aggressive investment takes 5–10 years to bring a new separation plant from permitting to production. Magnet manufacturing requires a further step: metallurgical expertise to produce consistent NdFeB grades meeting automotive and aerospace specifications. Japan's TDK and Shin-Etsu are notable non-China magnet producers, but they rely partly on Chinese feedstock for heavy rare-earth additions, tying them back into the chokepoint the controls targeted.
For policymakers, the implication is clear: stockpiling, recycling, and substitution research buy time, but only integrated mine-to-magnet supply chains outside China offer a structural solution. Until those chains reach scale, every EV, wind turbine, and precision-guided munition produced outside China depends, directly or indirectly, on Chinese rare-earth processing.
