Copper has a vast range of and industrial uses. Its superior electrical conductivity makes it ideal for electronics, such as wiring and computer connections; and its ability to heat up and cool down quickly makes it ideal for heat exchange applications such as air conditioners.
What is copper? Copper is an essential mineral found throughout all body tissues. It is a critical component of many enzymes. Symptoms of copper deficiency include neutropenia, hypochromic anemia, impaired immune function, bone abnormalities .
Sulfide ores are more important commercially. Ores are removed either by openpit or by underground mining. Ores containing as little as % copper can be mined profitably in openpit mining, but underground mining is profitable only if an ore contains %6% copper. The oxidized ores, such as cuprite and tenorite,...
Kennecott Power House. The ore deposits were primarily composed of chalcocite which is known for its higher copper content and ease of refining. In addition to copper, a significant amount of silver and small amounts of gold came out of the mine. From a variety of legal battles over the claims and company reorganizations took place.

The properties of copper are conductivity, malleability and resistance, and this metal provides the lowest electrical resistance next to silver. It is also very ductile and easily drawn into thin wires. Copper ores are much more abundant than native copper and are the major source of copper worldwide.
Copper is an example of this. Copper mostly occurs as sulfide ores, which are heated in air to convert them to copper(II) oxide. Molten copper can be produced from copper oxide by heating with carbon:
