Korea Zinc, a major minerals and metals company, has announced plans to invest $6 billion in building a critical minerals refinery in Clarksville and Gordonsville, Tennessee. This project is expected to create hundreds of jobs and marks the largest single private corporate investment in the state’s history.
The new facility will expand U.S. refining capacity for 13 critical minerals. Some of these minerals have recently been subject to export controls by China. The expansion of domestic refining capabilities aligns with legislative efforts in Congress, such as the Restoring American Mineral Security Act (S.2839), which was introduced by Senator Bill Hagerty (R-TN) alongside Senator Catherine Cortez Masto (D-NV). These efforts aim to reduce reliance on foreign supply chains and counter China’s influence over global mineral resources.
Senator Bill Hagerty commented on the development: “Korea Zinc’s decision to build a world-class critical minerals refinery in our state is not just an economic victory – it is a geostrategic one that directly supports President Trump’s efforts to restore American economic security in partnership with trusted allies, like South Korea,” said Senator Bill Hagerty. “This project will expand the United States’ capacity to produce the minerals that power our advanced industries and defense capabilities, strengthening national security while delivering high-paying jobs for hundreds of Tennessee families.”
The announcement highlights collaboration among federal, state, and local officials including Governor Bill Lee, Tennessee Department of Economic and Community Development Commissioner Stuart McWhorter, and the entire ECD team. Their involvement was instrumental in securing Korea Zinc’s commitment. The Tennessee Valley Authority also played a key role due to its energy infrastructure capable of supporting large-scale industrial operations.
