Chalcopyrite is the most abundant and wide spread ore of copper and in fact is the most abundant copper mineral. It occurs in a large variety of geological settings. The top two images above are from hydrothermal veins in base metal mines and the one below showing chalcopyrite's botryoidal (blister copper) form is from basalt in a trap rock quarry.

Chalcopyrite is the main ore of copper . Chalcopyrite is sometimes polished into beads and pendants as cheap jewelry. Chalcopyrite is a fairly common mineral, and therefore only the finest of localities will be mentioned. Large, well shaped crystals occur in numerous places in Cornwall, England, especially at the Carn Brea area.

Described as the world's most important ore of copper for nearly five thousand years is chalcopyrite. Some chalcopyrite has enough gold or silver that it can be an ore of those metals without the consideration of its copper content. Chalcopyrite is found in most sulfide mineral deposits throughout the world, which is its chemical classifiion.

Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of ore types, from huge masses as at Timmins, Ontario, to irregular veins and disseminations associated with granitic to dioritic intrusives as in the porphyry copper deposits of Broken Hill, the American cordillera and the Andes.

These deposits are rare compared with the other deposit types already discussed. They have produced significant amounts of zinc, lead, silver and sometimes copper. But, most of them are not economical to mine. Figure shows copper ore (mostly chalcopyrite and bornite) from the Rammelsberg SEDEX deposit in Germany.

 · Chalcopyrite the Peacock Ore. Chalcopyrite is the most important copper ore, and it is the primary source of many popular secondary copper minerals. It can occur in a variety of environments and forms, from hydrothermal veins to sedimentary layers. Nice chalcopyrite crystals are highly sought after by collectors.

 · Ninety percent of global copper resources are sulfide ores, where most of the copper is in the form of covellite (CuS), chalcocite (Cu 2 S), chalcopyrite (CuFeS 2), and bornite (Cu 5 FeS 4). Covellite and chalcocite are surface deposits and can be treated economically, but these resources are largely exhausted.
