Copper mining and the copper extraction process

Reasonable quality, high conductivity copper can be recycled by melting, though copper that has been brazed needs refining or can be used to make copper alloys. Where are the most important copper regions and producers? The largest copper mining country in the world is Chile, which produces 5.5 million tonnes per year.
