Recommendation

Rare earths are critical to making the magnets in many electronics, including cell phones and electric vehicles. China dominates the world’s supply, but the Western Hemisphere now has a contender: its only rare earth mine, closed for years, has reopened under new leadership. Maddie Stone reports in Fast Company that MP Minerals, the new owner of California’s Mountain Pass mine, plans to process rare earth metals with more environmentally sound methods than China uses. Anyone interested in economics, trade, politics, national security, or the US automotive, defense or high-tech supply chain has a stake in rare earths. 

Take-Aways

  • Rare earths are indispensable in many electronics, but their geographic distribution raises political issues.
  • The rare earth business in China is notoriously polluting, but US-based MP Materials is trying to create a greener supply chain.
  • Mining rare earths is just the first step; processing them raises additional geopolitical and environmental concerns.
