What is Copper?

  • For thousands of years, Copper is a metal that has been a part of our civilization. Silver, gold, copper, and Iron all have been made use in one way or another.
  • Copper(Cu) is one of those elements that were never actually discovered. They have been a part of each footstep in the growth of civilization. We keep on learning the diverse places where copper is made use of in nature.
  • The metal has been used for such an extended time as it can be found secluded as an unadulterated element. One could be tunnelling in a mine and stumble across unadulterated copper in various forms.
  • It is the 29th element in the periodic table represented by the symbol ‘Cu‘ short for the Latin name ‘cuprum’.

Uses Of Copper

  • Copper sulphate is used widely as an agricultural poison and as an algicide in water purification.
  • While one may not consider copper being used for something other than coins, it is a crucial element in the creation of bronze.
  • Historically, copper was the first metal to be worked by people. The discovery that it could be hardened with a little tin to form the alloy bronze gave the name to the Bronze Age.

Certain Facts About Copper

  • Copper is an essential element. An adult human needs around 1.2 milligrams of copper a day, to help enzymes transfer energy in cells. Excess copper is toxic.

Practise This Question

In a sad twist you inherit “only” a copper mine while your siblings inherit gold and diamond mines. On inspection you come to know that your copper mine is fully equipped to extract the metal from the ore and also that it consists only of Chalcopyrite. Finely powdered, pulverized ore is ready to be processed. What would be your next step?
