Rare Earth Elements |
Critical Minerals |
|
Definition |
These are a group of 17 chemically similar metallic elements (15 lanthanides plus scandium and yttrium). |
These are essential, non-fuel elements like lithium, cobalt, nickel, and rare earth elements (REEs). |
|
Abundance |
They are not rare, but rarely found in high concentrations, often mixed with radioactive thorium or uranium. |
Many critical minerals are not geologically rare, exist in significant quantities across the Earth’s crust. |
|
Application |
Essential for high-tech devices, defense systems, and green technology like electric vehicles and wind turbines. |
Vital for modern technology, defense, and clean energy (EVs, solar). |
|
Top producer |
China (roughly 60-69% of global mining production) followed by USA, Australia. |
China dominates, Australia (lithium), DR Congo (Cobalt), Indonesia (Nickel). |
|
Largest Reserve |
China holds the largest reserves, though smaller reserves in Brazil, Vietnam, India, Australia, and Russia |
Dominated by China, followed by Chile (lithium), Indonesia (Nickel). |
|
Supply Challenge |
Difficult extraction, environmental issues, geopolitical dependence. |
High demand, supply chain risks, and concentrated, limited supply. |
