What are Rare Earth Elementsand why they matter?
Rare earth elements comprise a group of 17 metallic elements that possess unique magnetic, optical, catalytic, and electrical properties. These characteristics make them indispensable in advanced manufacturing.
Demand for these materials is expected to grow substantially as countries expand clean energy technologies, digital infrastructure, and advanced manufacturing.
Rare earth elements comprise 3 sub-groups of 17 chemically similar metallic elements:
Light Rare Earth Elements (LREEs)
- Lanthanum
- Cerium
- Praseodymium
- Neodymium
- Samarium
Heavy Rare Earth Elements (HREEs)
- Europium
- Gadolinium
- Terbium
- Dysprosium
- Holmium
- Erbium
- Thulium
- Ytterbium
- Lutetium
Additional associated elements include:
- Scandium
- Yttrium
Although these elements are relatively abundant in Earth’s crust, economically recoverable concentrations are uncommon, and separating individual rare earths is technically complex and capital intensive.
Rare Earth Processing
Mining is only the first stage of the rare earth value chain. Producing usable materials requires:
- Mining
- Ore concentration
- Chemical cracking
- Solvent extraction
- Oxide production
- Metal refining
- Alloy production
- Magnet manufacturing
Countries that invest across this entire chain capture far more economic value than those that export raw ore alone.
Why Rare Earth Elements Matter
Rare earths are indispensable because they enable technologies that cannot easily be manufactured using alternative materials.
