China has just discovered the largest deposit of rare earths in the world. And he did it just when he needed it most.
China has a privileged position in terms of possession of rare earthbut it has just surprised the world with a new discovery: the Ministry of Natural Resources has confirmed that the Maoniuping deposit, in Sichuan province, is now the largest deposit of light rare earths on the planet. The news comes at a key moment, since it is these minerals that are the protagonists one of the hottest fronts between Beijing and Washington in their tariff war. What exactly has been found. New exploration in the Maoniuping mining area in Mianning county has confirmed the existence of 9.67 million tons of rare earth oxideswhich represents an increase of more than 300% compared to the reserves that were known until now, as announced by the Chinese Ministry of Natural Resources. With this data, the deposit surpasses that of Bayan Obo, in Inner Mongolia, which until now held the title of the largest light rare earth mine in the world with 44 million tons of proven industrial reserves. In addition to rare earth oxides, surveys have identified 27.1 million tons of fluorspar and 37.2 million tons of barite, both classified as deposits of exceptional scale. Why does it matter? Rare earth elements are the 17 elements that make electric car engines, fiber optic amplifiers, advanced weapons systems and smartphones possible, among many other technological elements that we use in our daily lives. Without them, much of the technology and defense industry simply does not work. China already produces more than 80% of the world supply annual of these materials, according to the state agency Xinhua. And this discovery further reinforces China’s position until now. The discovery within the discovery. According to Wang Denghong, director of the Institute of Mineral Resources of the Chinese Academy of Geological Sciences, what is truly striking about the discovery is not only the rare earths but fluorite and barite. Fluorite is an essential ingredient in the manufacturing of semiconductors and lithium-ion batteries. Barite, for its part, is essential in oil and gas extraction: it is used to stabilize wells and prevent blowouts. Without this element, hydrocarbon exploration, including fracking, would be paralyzed. Restrictions. Since April last year, China introduced export restrictions on seven rare earths and permanent magnets, precisely in response to the tariffs imposed by Donald Trump about Chinese products. China controls the gateway to rare earths, and basically any company that wants to take these materials out of the country needs express government authorization. Exports to Europe have picked up since the new licensing regime was implemented. Those going to the United States remain stagnant, according to collect Interesting Engineering. What’s coming now. With this discovery, Beijing consolidates its ability to use critical minerals as diplomatic and commercial leverage. The West has been trying for years diversify your supply chains of rare earths with projects in Australia, Canada or northern Europe, but none yet approach the scale of the Asian country.
