Rio Tinto's Kennecott Mine in Utah Key for Copper and Tellurium Production
Kennecott Mine, owned by Rio Tinto, is located in the Oquirrh Mountains, Utah, and is crucial for copper and tellurium production. The mine, known for being the largest man-made excavation, has been operational for over a century.
Initially discovered in 1848, copper became valuable in the late 19th century, leading to the establishment of Utah Copper Company in 1903. During the World Wars, the mine produced significant amounts of copper for military needs, accounting for 30% of U.S. copper during WWII.
Currently, it supplies 15-20% of U.S. copper demand, essential for modern technology and the green transition. Additionally, Kennecott produces tellurium, vital for advanced solar panels, and is one of only two U.S. producers.
A $1.5 billion expansion project is underway to extend operations to 2032, with underground mining commencing at North Rim Skarn by 2026. Sustainability efforts include transitioning to renewable diesel and extensive land reclamation.
