U.S. Faces Significant Challenges in Rare Earth Refining Dominance Despite Mining Capacity
The United States currently accounts for approximately 12% of global rare earth mining, but its worldwide refining capacity stands at a mere 1%, according to Moody's Ratings. This stark contrast highlights a critical dependency on foreign nations, particularly China, which dominates the rare earth supply chain with 91% of global refining activity and over 70% of the world's supply of rare earth metals. The U.S. has recognized its over-reliance on China for these essential materials, which are vital components in a wide array of high-tech products, including defense weaponry, automobiles, and consumer electronics. Efforts are underway, supported by federal backing and private investment, to develop domestic rare-earth production capabilities. A key focus of these efforts is the Mountain Pass mine in San Bernardino County, California, operated by MP Materials, which holds the world's largest deposit of carbonatite, a significant source of several rare earth elements, niobium, and phosphate.
