INTRODUCTION
Copper is a malleable, reddish brown metallic element, and one of the most widely used metals and probably the first metal from which useful articles were made. It is the most common conductor of electricity.
Due to its conductivity of electricity and heat, resistance to corrosion, malleability and ductility and its beauty, copper has long been used in a wide variety of applications.

ECONOMIC IMPORTANCE
* Copper is widely used for making electric wires due to its ductility and been the second most conductor of electricity after silver.
* It is used in producing a wide range of important alloys such as bronze, brass and cupronickel.
* It is used in metalwork because it is easy to work with, has an attractive appearance, and is resistant to corrosion.
* It has been used for coins throughout recorded history and has also been fashioned into cooking utensils, vats, and ornamental objects.
