Copper mining in the United States
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2007 the United States produced 1.19 million metric tonnes of copper, worth $8.8 billion, making it the world's third largest copper producer, after Chile and Peru. The nation produces 63% of the copper it uses, relying on imports from Chile, Canada, Peru, and Mexico for the remaining 37%. Top copper producing states in 2007 were (in order) Arizona, Utah, New Mexico, Nevada, and Montana.[1]
Copper mining activity has increased in recent years because of increased price: the price increased from an average of $0.76 per pound for the year 2002, to $3.02 per pound for 2007.[2]
