Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
In this article we will take you to some gigantic man-made holes: open pit mines. We'll show you the biggest, deepest and deadliest mines in the world.
Key points • Copper is malleable, ductile, and an extremely good conductor of both heat and electricity. • A computer contains around 1.5 kg of copper, a typical home about 100 kg and a wind turbine 5 tonnes.
That is good in the sense that despite a persistent deficit market narrative around copper for the last few years, the reality is the copper market is pretty much balanced, according to Reuters.
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2014 the United States produced 1.37 million metric tonnes of copper, worth $9.7 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru.

Missing: Prehistoric Michigan's Half-Billion Pounds of Copper By David Hoffman AA #35 pp.18-21 . Approximately 9,000 years ago, the Great Lakes achieved their current definition. Water levels would have been high near the time of the final glacier melt enabling human travel along ancient
As many of you know, copper is often seen as an indicator of economic health, historically falling when overall manufacturing and construction is in contraction mode, rising in times of expansion.
