# Chasing China’s Monazite Monopoly in Rare Earths Supply Analyzing China's strategic dominance and environmental legacy in global monazite ore processing. - **Source:** [IEEE Spectrum](https://spectrum.ieee.org/) - **Published:** 2026-10-15 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/2fbe5b82-ddde-409e-8663-57e8a54e3e2a ## The Baotou Environmental Legacy Baotou, an industrial hub of two million people, hosts the Weikuang Dam, a highly polluted ten-square-kilometer artificial lake. Built in the late 1950s, this site contains radioactive thorium resulting from decades of monazite ore processing. This environmental disaster forced China to implement strict regulations, effectively banning stand-alone monazite mining operations nationwide. ## Bayan Obo's Central Role The Bayan Obo complex, located 150 kilometers north of Baotou, remains the world's largest rare-earth deposit. While primarily an iron-ore mine, it produced 170,000 tonnes of rare-earth metal last year. Because it produces bastnaesite, mining monazite there is legally permitted, making it the primary source for China's domestic rare-earth supply chain. ## Strategic Importation Dynamics China imported over 70,000 tonnes of monazite ore last year, according to consultant Thomas Kruemmer. Due to radioactivity, concentrated monazite is classified as Class 7 dangerous cargo, limiting entry to only four Chinese ports. This regulatory framework involves state-owned entities like the China National Nuclear Corp and Shenghe Resources in oversight. ## Circumventing Import Controls Many companies bypass strict import controls by shipping heavy mineral sands containing only two or three percent monazite by weight. These sands are not subject to the same regulations as concentrated ore. Once inside China, firms separate the monazite concentrate from these sands to recover essential elements like dysprosium and terbium. ## Shifting Global Supply Chains Western nations are investing billions to reduce reliance on Chinese processing. The U.S. government recently committed $400 million to MP Materials and $725 million to Energy Fuels. These investments aim to secure monazite supplies from Australia, Brazil, and Madagascar, directly challenging China's long-standing dominance in the global rare-earth market. ## Strategic Asset Acquisitions China is aggressively securing rare-earth assets worldwide to compensate for lost supplies, such as the end of MP Materials' contracts with Shenghe Resources. Analysts suggest this is a strategic move to lock down global deposits, effectively making these resources unavailable to non-Chinese developers seeking to build independent, non-Chinese rare-earth supply chains. ## The Competitive Landscape David Merriman of Project Blue notes that the perception of these activities depends on one's geopolitical perspective. While Western nations view their own investments as essential for supply security, Chinese observers interpret these moves as strategic competition. China continues its long-term strategy of maintaining control over critical mineral processing infrastructure. ## Future Market Implications The global race for monazite highlights the tension between environmental sustainability and industrial necessity. As nations scramble to secure rare earths, China's historical experience with monazite processing serves as a cautionary tale. Future market stability depends on whether Western projects can successfully scale operations while navigating the complex regulatory and environmental challenges. ## Sources covering this story - https://spectrum.ieee.org/china-rare-earth-minerals — --- _Summary written by Brifing from the original reporting.
