From UPSC perspective, the following things are important :
Prelims level: Rare earth elements
Mains level: Not Much
Scientists at the National Geophysical Research Institute (NGRI) in Hyderabad have discovered the presence of rare-earth elements (REEs) in Anantapur district, Andhra Pradesh.
What are Rare-Earth Elements?
- Rare-earth elements (REEs) are a group of 17 elements, including lanthanum, cerium, praseodymium, neodymium, yttrium, hafnium, tantalum, niobium, zirconium, and scandium.
- These elements are widely used in modern electronics, such as smartphones, computers, jet aircraft, and other products, due to their unique magnetic, optical, and catalytic properties.
- These elements are crucial components in various electronic devices and have industrial applications in sectors like imaging, aerospace, and defense.
SHORE Project and discovery of REEs
- The discovery was part of a study funded by the Council of Scientific and Industrial Research (CSIR) under a project called ‘Shallow subsurface imaging Of India for Resource Exploration’ (SHORE).
- NGRI scientists found enriched quantities of REEs in “whole rock analyses”.
- Drilling for at least a kilometer deep will help ascertain the consistency of the elements’ presence underground.
Significance of the discovery
- The discovery of REEs in Anantapur district is significant as these elements are in high demand worldwide, and their supply is limited.
- REEs have become a subject of geopolitical concern due to their increasing demand and limited supply.
- China is currently the world’s largest producer and exporter of rare-earth elements (REEs), accounting for more than 80% of global production.
- The country has significant reserves of REEs and has invested heavily in mining and processing infrastructure.
