The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 percent of the world's total copper mine capacity. Chile and Peru, alone, account for about half of the copper mines on this list, but the U.S. does make the cut, with two mines among the top 20.

Innovations: Introduction to Copper: Mining & Extraction
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
Ores are removed either by open-pit or by underground mining. Ores containing as little as 0.4% copper can be mined profitably in open-pit mining, but underground mining is profitable only if an ore contains 0.7%-6% copper.
Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops.
Mining metals: Metals are often found as compounds in ores.An ore is a rock or mineral that has enough metal in it to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1000 kg of ore.
The KS Mine comprised a large open pit mine feeding gold-copper ore to a 52,000 tonnes per day (t/d) processing plant. Between 1998 and 2011, KS produced approximately 3.0 million ounces of gold and 750 million pounds of copper from 218 Mt of ore.

· Sometimes the copper ore mineral is different; for example, chalcocite (copper sulfide) is very different from malachite (copper carbonate with water).UNR has a nice write-up on basic open pit and underground mining technologies.
Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.

a horizontal passageway underground, which follows the vein or seam of the mineral ore. Drift mine – an underground coal mine that is accessed above water level. These are usually situated on the slope of a hill. Electro-refining – the use of electrolysis to improve the purity of the metal extracted from ore.
