What is copper PPT?
Introduction to Copper Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color.
What is Chile’s copper?
Overview. Chile is the top copper producer in world with 28 percent of global copper production and the world’s second largest producer of lithium with a 22 percent share of world production. In 2020, the sector produced 5.73 million tons of copper and 70 thousand tons of Lithium Carbonate Equivalent (LCE) in 2019.
Does Chile make copper?
Indeed, Chile is home to some of the world’s largest, better known copper mines. Approximately 80 percent of Chilean production comes from porphyry copper deposits rich in molybdenum, gold, and silver byproducts. Most such deposits lie in northern Chile (20º to 26º S).
What are the uses of copper?
Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).
