This Is How The US Can Become a Player in Rare Earth Metals

What It Covers

The US faces critical dependence on China for rare earth minerals essential to defense and technology. Heidi Kribo Rediker from the Council on Foreign Relations presents breakthrough biotech and materials science innovations that could bypass traditional mining, offering cost-competitive domestic alternatives through engineered proteins, rare-earth-free magnets, and waste recycling technologies.

Key Questions Answered

• •Biotech extraction methods: Companies like Alta Research Technology use genetically programmed proteins that target specific rare earth elements in waste streams, mine tailings, and e-waste. This approach eliminates environmental damage from traditional mining while accessing domestic resources. Berkeley researchers engineered harmless viruses to act as smart sponges, grabbing rare earths from water and releasing them with temperature and acidity changes for collection.
• •Rare-earth-free magnets: NIRON Magnetics commercialized technology from 2011 Department of Energy ARPA-E grants that creates magnets without rare earths. The company now scales production in Minnesota with a facility opening in 2027. This material engineering approach drastically reduces or eliminates rare earth requirements in magnets used across defense, automotive, and technology applications, directly challenging China's monopoly on magnet production.
• •Waste as strategic resource: The US produces massive quantities of e-waste, coal ash, and mine tailings containing recoverable rare earths. Old hard drives, cell phones, and batteries from earlier eras contain higher concentrations of rare earths than current products. Vulcan, only three years old, closed a 1.4 billion dollar Series A in August 2024, partnering with Reelement to recycle magnets and manufacture new ones domestically.
• •Equity valley of death: Breakthrough rare earth technologies face a specific funding gap that traditional debt-based government instruments cannot solve. In-Q-Tel, the CIA's venture capital arm, created the Compass Fund specifically to provide early-stage equity for critical mineral innovations. This addresses the market failure where private venture capital avoids difficult deep-tech investments, leaving viable technologies stranded between lab and commercialization despite national security urgency.
• •Industrial biotech for mining: Rio Tinto deploys proprietary microbes in Arizona copper mines to extract metals that were previously uneconomical through traditional methods. This biotech solution operates cost-competitively while avoiding environmental damage from conventional refining. The approach demonstrates how biological processes can unlock value from closed mines, offering a template for rare earth extraction that combines profitability with cleaner operations than China's state-subsidized, environmentally destructive model.
