#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. These include: #azurite, #malachite, chalcocite, acantite, chalcopyrite and #bornite. Most copper comes from #chalcopyrite.
The world’s leading producer of copper is #Chile, followed by the U.S. and #Peru. The majority of copper in the #USA is produced in #Arizona, Utah and New Mexico. Other major #copper producing nations include #Australia, #Canada, #China, #Mexico, #Russia, #Indonesia #and #Pakistan.
