How do critical minerals affect supply chains?
Critical minerals are raw materials important to energy, defense or digital technology whose supply is considered exposed to geographic and political risk.
Formation process and geographic mechanism
Location of mining, refining and component production matters as much as geology. Ore may be extracted in one country but processed by only a few facilities, creating bottlenecks. Grade, energy, water, ports and permitting slow new supply. Critical lists vary by country, technology and time.
Spatial outcomes, measurement and management
Diversification combines new mines, substitute materials, efficient use, recycling and strategic stocks. Moving production elsewhere does not remove environmental or social costs. Traceability, waste management and community participation are part of supply security. Rapid demand growth can increase short-term price volatility.
