Hyderabad: In a groundbreaking discovery, scientists at CSIR-National Geophysical Research Institute in Hyderabad have unearthed a trove of Light Rare Earth Elements (REE) in Andhra Pradesh's Ananthapur district. These minerals, including Lanthanum, Cerium, Praseodymium, Neodymium, Yttrium, Hafnium, Tantalum, Niobium, Zirconium, and Scandium, are key components in the electronic devices we use daily and a wide range of industrial applications like medical technology, clean energy, and aerospace. The scientists discovered strong anomalous concentrations of these elements in rock analyses, indicating their potential as an economically viable resource.
With manufacturing permanent magnets being the primary end use for REEs, the discovery is a significant milestone for the scientific community, as these magnets are crucial to modern electronics like cell phones, televisions, computers, and automobiles. Moreover, the luminescent and catalytic properties of REEs make them an essential component in high technology and green products. The European Union's goal to reach net-zero emissions will increase the demand for REEs by up to 26 times in 2050 compared to present demand.
The study was part of the SHORE project funded by the Council of Scientific and Industrial Research (CSIR-India), and the scientists used a multi-disciplinary approach to understand the rare metals and REE metallogeny, assess resources and identify economically potential sites. The discovery opens new possibilities for further exploration and development in the region. To determine the consistency of REE presence in depth, the scientists plan to undertake deep drilling of at least one km. This discovery is a promising step forward in the sustainable development of our society.
