Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho, and Missouri. As of 2014, the US had 45 million tonnes of known remaining reserves of copper, the fifth largest known copper reserves in the world, after Chile, Australia, Peru, and Mexico.

Mining in Bolivia has been a dominant feature of the Bolivian economy as well as Bolivian politics since 1557. Colonial era silver mining in Bolivia, particularly in Potosí, played a critical role in the Spanish Empire and the global economy. Tin mining supplanted silver by the twentieth century and the central element of Bolivian mining, and wealthy tin barons played an important role in national politics until they were marginalized by the industry's nationalization into the Bolivian Mining Corporation that followed the 1952 revolution. Bolivian miners played a critical part to the country's organized labor movement from the 1940s to the 1980s.
