Like iron mining, the extraction of copper has increasingly become an open pit enterprise. A peculiarity of the industry is that most copper mines yield small amounts of other nonferrous metals—especially gold and silver—as byproducts. The process of bringing metallic copper to market usually in-volves four distinct operations: (1) mining ...

Copper ore is mined using two primary methods: open-pit mining and underground mining. Open-pit mining is employed for deposits near the surface, where large machines dig into the earth in stair-stepped layers. Drilling equipment and explosives are used to extract the ore, which is then transported to ore-dressing plants by trucks or conveyors.
