KOREA ZINC PLANS US SMELTER AFTER BUYING NYRSTAR’S CLARKSVILLE PLANT
Korea Zinc is working with the US Department of Defense and Department of Commerce to redevelop the US's only zinc smelter, at Clarksville in the southern state of Tennessee, and plans to expand the facility to handle 13 non-ferrous metals, including copper, zinc and lead, along with critical minerals, such as antimony, gallium and germanium.
Announcing a $7.4 billion investment in the project, Korea Zinc said that it has agreed to buy the Clarksville zinc smelter, which has been in operation for almost five decades, from Nyrstar (a unit of commodity trader Trafigura).
The redeveloped smelter will have an annual capacity of 540,000 tonnes, Korea Zinc said, with commercial production expected to commence in 2029.
Work is scheduled to start in 2026 and will help the US curb its reliance on critical mineral imports.
Separately, Nyrstar confirmed that it had reached an agreement to sell the smelter to Korea Zinc for an undisclosed sum.
