Pyrite's name comes from the Greek, pyrites lithos, "the stone which strikes fire.". The crystals form in the Isometric System; cubes, octahedrons, pyritohedrons and combinations of these and other forms. It also may be found in radiating disks, hair-like crystals, concretions and massive lumps in sulphide ore deposits.
The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air. During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulfide and cuprous sulfide.

4As + 3O 2 → 2As 2 O 3. The copper pyrite is partly converted into sulphides of copper and iron. 2CuFeS 2 + O 2 → Cu 2 S + 2FeS + SO 2. 2FeS + 3O 2 → 2FeO + 2SO 2. The Process in summary: The concentrated ore is heated stoutly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces.
