Rare Earth Elements
Rare earth elements are a group of 17 chemical elements
that are critical to two of the fastest-growing sectors:
energy and high technology
Energy: High technology:
- Hybrid/Electric cars - Flat panel displays
- Wind turbines - Refrigeration
- Rechargeable batteries - Water filtration
- Catalysts - Defense applications
New applications are constantly being developed for
rare earths given their unique attributes

Tantalum and Niobium
Tantalum and niobium are both rare metals strategic
to the electronics and steel industries respectively
Tantalum is primarily used to manufacture electronic
capacitors. Used in everyday items like:
• Cell phones
• Computers
• Digital audio/video players and cameras
• LCD/plasma televisions
• Gaming devices
Niobium is primarily used as an alloy for the
production of harder and greater load-bearing steel
(used in: bridges, buildings, and oil and gas pipelines).

Recent Developments in the Tantalum Market
In 2010, tantalum prices have risen dramatically Demand Ta2O5 in Concentrate
(from US$45-60 to $100+/lb in a concentrate) in
response to:
Supply Constraints
• Increasing global pressure on the procurement
of tantalum from conflict regions in Central Africa,
principally the DRC
• US legislation on conflict minerals
• Diminishing inventories and stockpiles
• Suspended/reduced production Demand Growth
Growth in the global demand for
Long term: market requires additional production tantalum is expected to
from projects situated in politically stable countries continue at rates of between
that can demonstrate legitimate, long-term supply 8-12% per annum (CAGR)
