The United States has largely ceded its rare earth element processing industry to China over the past two decades, creating a strategic vulnerability that extends far beyond mining. While American companies can extract raw materials, the technical expertise to refine them into usable form has migrated overseas, leaving the nation dependent on foreign processing facilities for critical components in semiconductors, defense systems, and renewable energy technology.
The Biden administration has invested billions in domestic mining through the Inflation Reduction Act and infrastructure spending. Yet those initiatives address only half the problem. Processing rare earth elements requires specialized knowledge, specialized equipment, and specialized infrastructure that China dominates. Without domestic processing capacity, mined American ore still requires international shipping and foreign refinement.
Rebuilding processing expertise demands more than capital investment. The US must recruit or retrain workers familiar with complex chemical separation techniques. Universities need to expand materials science and chemical engineering programs focused on rare earth refining. Private companies require long-term government contracts to justify the upfront costs of building processing plants.
China controls approximately 70 percent of global rare earth processing capacity. That dominance gives Beijing leverage over American manufacturers and military suppliers. In times of geopolitical tension, the Chinese government could restrict exports, forcing American producers to halt production lines.
Several startups and established firms now attempt to establish domestic processing. MP Materials operates a rare earth mine in California but ships concentrates to Malaysia for processing. Lynas Rare Earths and others propose new American facilities, but construction timelines stretch years ahead.
Policy solutions exist. Congress could tie defense procurement contracts to domestic processing requirements. Tax credits could accelerate facility construction. Strategic government partnerships could guarantee purchase agreements, reducing investor risk.
The processing gap represents a blind spot in America's critical minerals strategy. Mining without processing capacity leaves the supply chain incomplete. Closing that gap requires the same focus on technical expertise and long-term industrial policy that built American manufacturing dominance in previous
