Chinese geologists have made a groundbreaking discovery at the world’s largest rare-earth mine in northern China. The Chinese Academy of Sciences (CAS) announced the finding of two new minerals, Oboniobite and Scandio-fluoro-eckermannite, at the Bayan Obo deposit in the Inner Mongolia Autonomous Region.
Through a collaborative effort between the CAS Institute of Geology and Geophysics, Inner Mongolia Baotou Steel Union Co., Ltd., Baotou Research Institute of Rare Earths, and Central South University, these new niobium-scandium minerals were identified and confirmed by the International Mineralogical Association.
Niobium and scandium are vital metals with various industrial applications, including in aerospace, steel production, and energy technology. The discovery of these new minerals is significant for China’s economic and social development, according to CAS academician Li Xianhua.
The general manager of Inner Mongolia Baotou Steel Union Co., Ltd., Li Xiao, highlighted the rich mineral resources present at Bayan Obo, emphasizing the importance of ongoing mineral exploration in the region. This recent discovery marks the 19th and 20th new minerals found at the deposit since 1959.
Researcher Fan Hongrui described Oboniobite and Scandio-fluoro-eckermannite, noting their unique characteristics and significance. Scandio-fluoro-eckermannite, in particular, is the first mineral in China to contain scandium and is named after CAS academician Zhai Mingguo for his contributions to mineral studies in the country.
The discovery of these new minerals showcases China’s continued advancement in scientific research and mineral exploration, with potential implications for various industries and technological developments.
