Production trends in the top five copper-producing countries, 1950-2012. This is a list of countries by mined copper production. Copper ore can be exported to be smelted so that a nation's smelter production of copper can differ greatly from its mined production. See: List of countries by copper smelter production.
Kilembe Mines is known to contain reserves and resources of copper in ore and tailings, as well as potential for cobalt, copper, and associated base metals, making it a key element in the transition to clean energy. The current price of copper is between $ 10,000 and $ 10,500 per tonne. [8]
In the United States, copper mining has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the US 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.
Porphyry copper deposits represent an important resource and the dominant source of copper that is mined today to satisfy global demand. [6] Via compilation of geological data, it has been found that the majority of porphyry deposits are Phanerozoic in age and were emplaced at depths of approximately 1 to 6 kilometres with vertical thicknesses on average of 2 kilometres.

The mines of the Keweenaw native copper deposits of Upper Michigan were major copper producers in the 19th and early 20th centuries, and are the largest deposits of native copper in the world. [6] Native Americans mined copper on a small scale at this and many other locations, [ 7 ] and evidence exists of copper trading routes throughout North ...
