Minable concentrations of bornite occur in hydrothermal veins, contact metamorphic zones, and in the enriched zone of many sulfide mineral deposits. Chalcopyrite, marcasite, and pyrite are other sulfide minerals commonly associated with bornite. Small amounts of bornite are also found disseminatSee more on geology
  • Chalcocite Wikipedia

    Chalcocite (UK: ˈ k æ l k ə ˌ s aɪ t /), copper(I) sulfide (Cu 2 S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster.It has a hardness of 2 1 ⁄ 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.

    Jul 02, 2011· At a depth of 47 m, it intercepted a layer of chalcocite mineralization 49 m thick with an average content of 1.17% copper and 0.21 g/t gold. Interestingly, under the chalcocite blanket, there was a zone of hypogene copper mineralization containing covellite with a 252 m interval, which returned grades of 0.61% copper and 0.11 g/t gold.

  • 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).
