Copper Facts Copper is a natural element – a metal that has been one of mankind’s most useful and valuable materials. It is represented by the chemical symbol Cu and the atomic number 29.
Copper is also an essential nutrient that is required by virtually all higher life forms. It is an essential component of dietary nutrition that enables the body to metabolize energy and function properly. As with humans, plants and animal health rely on adequate copper intake. The world’s two most important food crops – rice and wheat – are both highly dependent on sufficient copper in soil.
Copper has been indispensable to human progress. In fields ranging from medical equipment to energy efficiency, from jet planes to satellites, from television to the Internet, Copper is vital to our well being in day-to-day life.
Copper is by far the most sustainable gift of nature’s bounty. For as long as humans have put copper to use, they have taken advantage of the fact that it is virtually one hundred percent recyclable. It has always made economic sense to retrieve as much copper as possible from a product, at the end of its life cycle, and re-use it for some new purpose. Moreover, most copper in use, such as roofing, wiring, and plumbing, will remain in use for over half a century. Copper Insights Some of the earliest uses of copper we know of dates back to the cave men who used axes and other weapons made of copper. All the way from the Egyptian pyramids to Mohenjo Daro, archaeologists have discovered copper used to make statues and even plumbing systems. What surprised them was the fact that the plumbing was found to still be serviceable in our time!
Ancient belief systems found to be based on scientific facts have proven that Copper, drinking water in copper vessels due to the metal’s anti-fouling properties. considered to be a ‘pure’ metal was best for storing food. Our ancestors would store

Copper is one of the best and safest conductors of electricity and has replaced aluminium in all areas including house wiring. Think about this:
Replacing all Aluminium wound transformers with copper can result in annual energy savings of 4500 million kehr of energy and Rs. 1800 crores for India.
The daily dietary recommendation of copper for an adult is 1-2 mg and for a child is 0.5-I mg.
