Abstract. The metallogenetic role played by the Corocoro copper mine (La Paz Department, Bolivia), formerly considered to be the most important producer of copper in Bolivia, has been emphasized by several authors in their detailed studies. This important role explains in part, why the genesis of these cupriferous ores has, in the past, led to ...

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
