COPPER-PYRITES, or Chalcopyrite, a copper iron sulphide (CuFeS2), an important ore of copper. The name copper-pyrites is from the Ger. Kupferkies, which was used as far back as 1546 by G. Agricola; chalcopyrite (from XaXK6s, "copper," and pyrites) was proposed by J. F. Henckel in his Pyritologia, oder Kiess-Historie (1725). By the ancients copper …

Let us now see the extraction of copper from its ore. The ore of copper which is used is the copper pyrite. Iron is one of the impurities present in the copper pyrite ore. We have to remove the iron by roasting the pyrite ore. Roasting is the process which involves heating with excess supply of oxygen.
