What follows are key findings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. China-centered dominance is measurable\u2014and enormous<\/h3>\n\n\n\n<p>The model estimates that China accounts for 68.57% of global Tb flows, with cumulative Tb flow\/production on the order of ~1.05 \u00d7 10\u2074 tonnes in the authors\u2019 accounting. This is not merely \u201cmarket share.\u201d It reflects system-level leverage\u2014the capacity to convert feedstock into separated materials and high-value Tb-bearing products, and to influence how much leaves China and in what form.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Ion-adsorption clays are a strategic lever<\/h3>\n\n\n\n<p>China\u2019s ion-adsorption clay deposits supply 53.8% of China\u2019s Tb output, translating to roughly 39.5% of global Tb production in the authors\u2019 estimate. These deposits\u2014mainly in southern China\u2014are disproportionately important for heavy rare earths and help explain why Tb remains a hard-to-replace chokepoint metal in the modern industrial chain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. The end-use story has flipped: from lamps to magnets<\/h3>\n\n\n\n<p>Terbium once flowed primarily into phosphors for fluorescent lighting (peaking at 74.5% of market flow in 2007). The paper shows that this era has been overtaken by the magnet economy: since 2014, the center of gravity shifted toward magnets, and post-2021, ~90% of Tb flows are tied to permanent magnets. That transition tracks the real economy\u2014electrification, automation, and high-efficiency motors scaling faster than legacy lighting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Recycling potential exists\u2014but the system isn\u2019t ready<\/h3>\n\n\n\n<p>The authors identify the most significant near-term \u201curban mine\u201d for terbium in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fluorescent lamps (estimated recovery potential ~381.8 t)<\/li>\n\n\n\n<li>Home appliances, a growing and steady stream of Tb-bearing end-of-life products<\/li>\n<\/ul>\n\n\n\n<p>They argue that without industrial-scale recycling, constraints will intensify\u2014especially as future end-of-life waves arrive from longer-lived assets like wind turbines and <a class=\"wpil_keyword_link\" href=\"https:\/\/rareearthexchanges.com\/news\/new-energy-vehicles\/\" title=\"China\u2019s Automotive Market Achieves Robust Growth in November, Led by New Energy Vehicles\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"52015\">new energy vehicles<\/a>, which can create delayed but substantial recovery needs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"the-re-ex-lens-plus-implications-for-chinas-processing-dominance\">The REExLens Plus Implications for China\u2019s processing dominance<\/h2>\n\n\n\n<p>This authors here reinforce a central <a class=\"wpil_keyword_link\" href=\"https:\/\/rareearthexchanges.com\/reex-insights\/\" title=\"REEx Insights\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"105701\">REEx<\/a> point: China\u2019s advantage is not only geology\u2014it is industrial integration. Even if new mines come online elsewhere, terbium\u2019s strategic vulnerability often sits in separation, metallurgy, and magnet-material conversion. The paper\u2019s trade mapping suggests that global Tb flows remain heavily concentrated around China-centric routes, including bidirectional dynamics where China imports certain inputs while exporting higher-value Tb-bearing forms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Implication 1: Ex-China supply is not \u201cjust build a mine.\u201d<\/h3>\n\n\n\n<p>Tb is a chokepoint metal. A mine without downstream separation, metallurgy, and qualified magnet production does not resolve strategic dependency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Implication 2: Recycling is strategically real\u2014but operationally immature.<\/h3>\n\n\n\n<p>The study frames recycling as essential, but underscores that scaling requires policy alignment, industrial capacity, and reliable collection streams\u2014not just lab validation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Implication 3: Environmental and governance risk is part of the supply chain.<\/h3>\n\n\n\n<p>The paper highlights environmental leakage from mining\/smelting and discusses persistent informal\/illegal mining dynamics in heavy <a class=\"wpil_keyword_link\" href=\"https:\/\/rareearthexchanges.com\/?post_type=acf-post-type&amp;p=38\" title=\"News\" data-wpil-keyword-link=\"linked\" data-wpil-monitor-id=\"100692\">rare earth<\/a> feedstocks\u2014reminding readers that \u201cclean tech\u201d demand can be linked to supply routes carrying ecological and governance liabilities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"limitations-what-this-study-cannot-prove\">Limitations: what this study cannot prove<\/h2>\n\n\n\n<p>This is a rigorous systems analysis\u2014but it remains a model.

As electrification and automation expand, Tb demand is increasingly pulled toward permanent magnets, where performance requirements tighten supply tolerance. The authors show that China\u2019s dominance is structurally rooted in heavy rare earth feedstocks and, crucially, downstream conversion capacity. For investors and policymakers, the message is clear: diversification requires processing, recycling, and industrial scale\u2014not slogans.<\/p>\n\n\n\n<p>Citation: Liu W., Guo W., Chen J., et al. <em>Tracking terbium metabolism in China with implications for its dominance in global rare earth supply.<\/em> Resources, Environment and Sustainability (2025). <a href=\"https:\/\/doi.org\/10.1016\/j.resenv.2025.100263\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"external-link\">https:\/\/doi.org\/10.1016\/j.resenv.2025.100263<span class=\"sr-only\"> (opens in a new tab)<\/span><\/a> <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2666916125000751?utm_source=chatgpt.com\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"external-link\">ScienceDirect<span class=\"sr-only\"> (opens in a new tab)<\/span><\/a><\/p>\n\n\n\n<p>\u00a9!-- \/wp:paragraph --&gt;<\/p><span class=\"et_bloom_bottom_trigger\"><\/span>","protected":false},"excerpt":{"rendered":"<p>China controls 68.57% of global terbium flows.
