ore chalcocite bornite

Bornite - Wikipedia

Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Bornite is also found as disseminations in mafic igneous rocks, in contact metamorphic skarn deposits, in pegmatites and in sedimentary cupriferous shales. It is important as an ore for its copper content of about 63 percent by mass.

Chalcocite - Wikipedia

Chalcocite , copper(I) sulfide (Cu2S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster. It has a hardness of ​2 ⁄2 - 3 on the Mohs scale. It is a sulfide with an orthorhombic crystal system. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning copper. It is also known as redruthite, vitreous copper and copper-glance.

Chalcocite: The mineral Chalcocite information and pictures

Chalcocite forms from the alteration of other minerals, especially other copper sulfides such as Bornite, Covellite, and Chalcopyrite, and may also form pseudomorphs after these minerals. It often forms in association with Chrysocolla, with the Chrysocolla forming as an alteration around the Chalcocite.Chalcocite is named after the Greek word chalcos, which means "copper" in Greek, in

Chalcocite - an overview ScienceDirect Topics

Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S). The concentrations of these minerals in an ore body are low. Typical copper ores contain from 0.5% Cu (open-pit mines) to 1−2% Cu (underground mines).

May 21, 2014  The sulfide bornite [Cu 5 FeS 4] is also an important copper ore (close to 65% by mass), especially in the copper porphyry deposits. It is Orthorhombic but commonly is massive and/or granular in habit. It does not display the brassy color of pyrite or chalcopyrite until tarnished but is a mottled brown/black/purple to copper-red but often is mixed with chalcopyrite. It easily tarnishes upon ...

Both apparently get sold as Peacock Ore with an acid bath.

Bornite is also known as “purple copper ore” and “variegated copper ore.” Bornite crystals are uncommon. Although they exhibit orthorhombic symmetry, crystals, when found, are cubic, octahedral, or dodecahedral, often with curved or rough faces. Bornite is frequently compact, granular, or massive and alters readily to chalcocite and ...
