Introduction to Aluminum

  • Symbol Al and atomic number 13.
  • Aluminum occurs in abundance on the surface of the earth.
  • Aluminum makes up about 8% of the Earth’s crust.
  • It is available in various forms such as oxide, sulphates, silicates, phosphates etc.
  • Mostly it is commercially produced mainly from bauxite.
  • Aluminum is remarkable for the metals low density and for its ability to resist corrosion due to the phenomenon of “Passivation”.

 

Introduction to Copper

  • Copper was first used as early as 10,000 years ago. A copper pendant from about 8700 B.C. was found in what is now northern Iraq.
  • In about 3000 B.C. , large deposits of copper ore were found on the island of Cyprus in the Mediterranean Sea.
  • When the Romans conquered Cyprus, they gave the metal the Latin name aes cyprium, which was often shortened to cyprium.
  • Later this was corrupted to cuprum, from which the English word copper and the chemical symbol Cu are derived.
  • Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29.
  •  Copper is found as native metal and in minerals ie. cuprite, azurite, chalcopyrite and bornite.
  • The most common sulfide ore is chalcopyrite, CuFeS , also known as copper pyrite or yellow copper ore. Chalcocite, Cu S, is another sulfide ore.
