Rare Earth Deposits and Industry Potential in India
-
Geological Domains & Key Deposits:
-
Beach placers: Major REE deposits found along the eastern and southern coasts of India.
-
Chotanagpur Granite Gneiss Complex: Hosts heavy REE-bearing stream placers in Jharkhand and Chhattisgarh.
-
Carbonatite-hosted deposits (Western India):
-
Amba Dongar and Kamthai – major carbonatite REE sites.
-
Samchampi complex – low-grade yttrium (Y) ore.
-
-
Siwana Ring Complex (Rajasthan):
-
Hosts low-grade heavy REE (HREE) in (per)alkaline microgranite dykes and tuffs.
-
-
Kanigiri granite (Andhra Pradesh):
-
Rich in REE, niobium (Nb), tantalum (Ta), and thorium (Th).
-
-
Hydrothermal Veins:
-
Along Singhbhum Shear Zone and South Purulia Shear Zone – contain significant REE.
-
Kasipatnam area also shows REE potential.
-
-
-
Recommendations for Industry Development:
-
Planned resource utilisation based on deposit size and distribution:
-
Large-scale mining for vast deposits.
-
Small-scale/artisanal mining for scattered, small deposits.
-
-
Strengthen upstream and downstream sectors to identify and sustain REE resources.
-
Promote innovation through IT and materials engineering integration.
-
-
Strategic Importance:
-
Align REE development with Atmanirbhar Bharat, Mine in India, and Make in India initiatives.
-
Aim for self-reliance in critical minerals through sustainable and technological advancement.
-
-
Monazite:
-
A major source of rare earth elements (REEs) and thorium.
-
Thorium is a “prescribed substance” under the Atomic Energy Act.
-
-
Rare Earth Elements (REEs):
-
Includes 17 elements like cerium, lanthanum, neodymium, dysprosium, yttrium, etc.
-
Critical for electronics, defense, clean energy, and space technologies.
-
-
National Critical Minerals Mission (NCMM):
-
Launched to ensure secure, sustainable supply of critical minerals including REEs.
-
Aims to reduce dependence on China for rare earth supplies.
-
-
Global Significance:
-
India has strategic reserves of rare earths and thorium, positioning it as a key global player in future energy and technology sectors.
