Internal Geometric and Electronic Structures of Natural ...

The geometric and electronic structures of bornite (Cu5FeS4) were studied using the first-principle calculation based on density function theory. By analyzing the results, a mixed bonding state is found in bornite, which is a strong covalent bond with much weaker ionic bonds. The interaction between S and Fe is stronger than that between S and Cu.

Bornite Mineral Information, photo and Facts: Copper Ore

Bornite and chalcopyrite are the two common original copper minerals, from which other copper minerals have been derived through secondary action. It is also frequently, itself, a secondary mineral, formed in the upper, enriched zone of copper veins through the action of descending copper-bearing solutions, upon chalcopyrite.

Chalcopyrite - Wikipedia

Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid.
