Rare Earths

What are Rare Earths?
Rare earths refer to a group of 17 naturally occurring metallic elements with unique properties and a wide range of industrial applications. These are critical inputs for the global transition to a low-carbon economy, particularly in the production of clean energy technologies. Their critical role in the advancement of technology and sustainable development underscores the importance of securing a stable supply of these elements. REEs are divided into two categories:
Light Rare Earth Elements (LREEs)
These include elements like lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm), which are more abundant and generally have a lower atomic weight.
Heavy Rare Earth Elements (HREEs)
These consist of elements such as terbium (Tb), dysprosium (Dy), and yttrium (Y). They are less abundant and have a higher atomic weight.

GMDC’s Portfolio Includes High Purity Light Rare Earth Oxides

Neodymium

and praseodymium are integral to making the strongest magnets—permanent magnets; critical for motors in EVs and wind turbines.
Cerium finds its application as a catalytic converter in the automotive industry, polishing powder for glass products, and electrical components.
Lanthanum is primarily used in the catalytic cracking process in the petroleum industry, electronics and optics industries, and batteries for hybrid cars.
Our Vision
Developing India’s Sustainable Permanent Magnet Supply Chain
We aim to develop an end-to-end REE value chain from

rare earth mining

, processing, separation, and end-product manufacturing. We are coming up with one of the world’s top rare earths processing hubs in India. The hub will bring together the entire REE value chain and enable players to engage in downstream activities across industries such as metals and alloys,

NdFeB

magnets,

electric motors

, glass, and

optical glass

manufacturing in India.
Mining and Beneficiation at Ambadungar
GMDC is developing one of the world’s largest

rare earth

deposits at Ambadungar, a village in Chota Udepur district of Gujarat. The development consists of an open pit mine, processing plants, tailings storage facility, water supply, bulk power supply, mine infrastructure, workshops, offices, modern residential facilities with a best-in-class living ecosystem.
Our Ambadungar deposits contain light rare earth elements or

LREE’s

which are
critical minerals
for most economies globally. The ore will be mined from an open-pit mine and transferred for processing through crushing, milling, conditioning and floatation to form a mixed rare earth concentrate.
Separation and Integrated Downstream Manufacturing at Bharuch
The mixed rare earth carbonate produced at Ambadungar will be transferred to our separation plant in our

REE

hub at Bharuch. The end-result from this separation process will be the valuable rare earth oxides – Nd, Pr, La, Ce.
These separated oxides will be converted into metals and further used in manufacturing products such as catalysts for catalytic cracking as well as

rare earth magnets

–which serve as the cornerstone for global transition to

clean energy

and mobility.
