Scientists at the CSIR-National Geophysical Research Institute (NGRI) in Hyderabad have detected the presence of Light Rare Earth Elements (REE) in a number of electronic devices and various industrial applications including medical technology, aerospace and defence. Andhra Pradesh.
Light rare earth element minerals include lanthanum, cerium, praseodymium, neodymium, yttrium, hafnium, tantalum, niobium, zirconium, and scandium.
PV Sundar Raju, Senior Principal Scientist, NGRI, told the press, “We found strong heterogeneous (enriched) light rare earth elements (La, Ce, Pr, Nd, Y, Nb and Ta) in the whole rock analysis, which host these REEs. do confirm the minerals.” India’s trust
The rare earth elements (REEs) are the 15 elements referred to as the lanthanide and actinide series in the periodic table of elements, along with scandium and yttrium.
REEs are key components in many electronic devices we use daily (such as cell phones) and various industrial applications including medical technology, clean energy, aerospace, automotive, and defense.
The manufacture of permanent magnets is the largest and most important end use for REE, he added.
Permanent magnets are essential to modern electronics, used in cell phones, televisions, computers, automobiles, wind turbines, jet aircraft, and many other products.
Due to their luminescent and catalytic properties, REEs are widely used in high technology and “green” products.
“To reach net zero, Europe will need 26 times more rare earth metals than current demand in 2050. Demand is also increasing due to digitisation,” he added.
The discovery of REE was part of a study funded by the Council of Scientific and Industrial Research (CSIR-India) under a project called SHORE (Shallow Subsurface Imaging of India for Resource Exploration).
Sundar Raju said the scientists had a multi-disciplinary approach to the Noise project.
“Under this project umbrella, our focused objective is ‘detailed understanding of RM (rare metal)-REE metallogeny, resource estimation and identification of economically potential sites, especially from the carbonatite-syenite complexes of Andhra Pradesh'” ‘ Was.
He added that after the discovery of REE, at least a deeper drilling of more than one km would reveal the continuum of REE presence in depth.
