Jun 25, 20190183;32;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.

Copper is a malleable, ductile reddish metal, and is one of only two strongly colored metals (gold being the other). Copper is a stable metal largely unaffected by water and air, although carbon dioxide will react with the surface of pure copper to form greenish copper carbonate.
Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).

Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals that occur in deposits large enough to mine.
Tiny Copper crystals throughout this specimen as well as Cuprite crystals. The Levant mine is one of the most famous mines in the world having been perched high on the cliffs above the Atlantic ocean. It was a major producer of copper and tin. Mine workings reached more than a mile out beneath the sea and to a dept of 2000 feet.
There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using todays compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, its roasted, which helps to convert sulfides to oxides.
