A Chinese research team has discovered a new rare-earth mineral named "Neyu River Mineral."

Recently, it was learned from China University of Geosciences (Wuhan) that the university, in collaboration with the Geological Survey Institute of Inner Mongolia Autonomous Region, has discovered a new rare-earth mineral in the central part of the ore body within the main mining section of the Baiyun Obo deposit in Inner Mongolia. The mineral has been named "Neodymium Huanghe Mine."
It is reported that the mineral "Neodymium Yellow River" recently received unanimous approval from the New Minerals Nomenclature and Classification Committee of the International Mineralogical Association.
Zhao Laishi, leader of the research team and researcher at the National Key Laboratory of Geological Processes and Mineral Resource Prediction at China University of Geosciences (Wuhan), explains that the Neodum-Huang River mineral belongs to the rare-earth carbonate mineral family and boasts a unique chemical composition marked by its exceptional enrichment in neodymium. As a key component in high-performance permanent magnet materials, neodymium is in strong demand across industries such as new-energy vehicles, wind power generation, and advanced information technology.
The Baiyun Ebo mine is the world's largest rare-earth deposit and also serves as China's treasure trove of mineral resources, with more than 210 minerals already discovered there. Zhao Laishi stated that the discovery of the Neodymium Yellow River ore further highlights the mine's complex nature and diverse resource potential.
Zhao Laishi introduced that, during their project research, the team conducted systematic field geological surveys and geochemical analyses, revealing the rare earth element distribution patterns and occurrence characteristics of the Bayan Obo deposit. Building on these findings, they have now established the orebody zoning features and the genetic model of the Bayan Obo deposit.
The neodymium-rich Huanghe mineral was a new discovery made through micro-area mineral analysis, guided by this ore-forming model theory. Previously, the team had also identified two additional rare-earth minerals from Bayan Obo—fluorocarbonite-neodymium and neodymium-monazite.
