Escondida Copper Mine, Atacama Desert, Chile

Escondida means “hidden” in Spanish, and it refers to the fact that the copper ore body was buried beneath hundreds of meters of barren rock, and the surface geology gave no signs of its presence. Instead it had to be located by a laborious drilling program following a geologic trend—an imaginary line hundreds of kilometers long ...

Copper Mineral Uses and Properties - Geology

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).
