Bornite is an important copper ore mineral. It ranks up there with many of the other copper ores such as chalcocite, chalcopyrite, covellite, digenite, cuprite and tetrahedrite. As a mineral specimen, bornite is usually lacking. Good crystals are rare and thus bornite is commonly known as simply a massive mineral

Experimental replacement of chalcopyrite by bornite

The ensuing solid-state replacement of chalcopyrite by bornite was studied both texturally and chemically. The relatively oxidizing conditions of the reaction chalcopyrite+covellite result in “massive replacement”, lacking structural control, where bornite and pyrite form complex intergrowth textures in chalcopyrite. Bornite nucleates

Bornite " Peacock Ore " Raw Rough Crystal Mineral

Bornite is a copper iron sulfide mineral with a chemical composition of Cu5FeS4. Small amounts of bornite are also found disseminated through mafic igneous rocks and carbonaceous shales. Bornite is easily recognized because it naturally tarnishes to iridescent shades of

Mineral description : Bornite

Bornite is an important copper ore. Occurance : In igneous rocks, pegmatites, hydrothermal veins. Also in the oxidation zones of copper deposits together with malachite. Associates : Notes : Often gets a bluish tarnish on exposed surfaces. Easily soluble in acids. Named after the Austrian mineralogist, I. von Born (1742-1791). Approved by IMA

Bornite Hyperleap

Bornite, also known as peacock ore, is a sulfide mineral with chemical composition Cu 5 FeS 4 that crystallizes in the orthorhombic system (pseudo-cubic). It is important as an ore for its copper content of about 63 percent by mass.

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.

Mössbauer study of bornite and chemical bonding in Fe

Abstract. The Mössbauer spectra of a nearly stoichiometric natural bornite, Cu 5 FeS 4, specimen were reinvestigated between 295 and 4.2 K.There is no difference between the Neél temperature T N as determined by the Mössbauer effect or by the susceptibility measurements (T N = 67.5 K). No additional paramagnetic doublet can be observed in the low-temperature MS spectra.
