The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.

It colour is brass-yellow and tarnishes to gray green and It is chemical composition of CuFeS2. It is hardness of 3.5 – 4 on the Mohs scale and diagnostic properties streak is black green, ...
Chalcopyrite is a of the tetragonal crystal system. Crystallographically the structure of chalcopyrite is closely related to that of zinc blende ZnS (sphalerite). The unit cell is tw as large, reflecting an alternation of Cu and Fe ions replacing Zn ions in adjacent cells.
07-10-2020· Roasting is carried out in extraction of metal in how many ores/minerals?
Chalcopyrite, magnetite, Cassiterite containing impurity of pyrites of Fe and Cu, Galena, Zinc blende, Siderite, Updated On: 10-7-2020
Introduction. Chalcopyrite is the principal ore mineral of copper (Geoscience Australia, 2015).Concentrates produced from chalcopyrite-rich ores may also be enriched significantly in other elements. Silver is one such element and is commonly extracted as an economic by-product during copper smelting and refining (Ayres et al., Reference Ayres, Ayres and Råde 2013).
24-01-2013· The mineral chalcopyrite (CuFeS 2) is the world's most abundant source of copper, a metal component in virtually every piece of electrical equipment. It is the main copper mineral in several different ore deposit types, the most important of which are porphyry deposits.
Chalcopyrite (/ ˌ k æ l. k ə ˈ p aɪ ˌ r aɪ t,-k oʊ-/ KAL-kə-PY-ryte, -koh-) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS 2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale.Its streak is diagnostic as green tinged black.
The Vathi porphyry Cu-Au±Mo deposit is located in the Kilkis ore district, northern Greece. Hydrothermally altered and mineralized samples of latite and quartz monzonite are enriched with numerous rare and critical metals. The present study focuses on the bulk geochemistry and the mineral chemistry of pyrite, chalcopyrite, magnetite, and titanite.
14-06-2021· are also potential sources of rare metals, mainly as by-products [9–12]. Pyrite and chalcopyrite are common sulfides in various types of metallic mineraliza-tion, whereas magnetite and titanite are common accessories and, therefore, have been used as indicator minerals for specific ore types [13–26]. Over the last 20 years, several
03-12-2012· Inactivation of the gene encoding the M. sedula copper efflux protein, copA, using targeted recombination compromised metal resistance and eliminated chalcopyrite bioleaching. In contrast, a spontaneous M. sedula mutant (CuR1) with elevated metal resistance transformed chalcopyrite at an accelerated rate without affecting chemoheterotrophic growth.
07-06-2021· The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas.
Cu in chalcopyrite, but all the metals were originally dis-persed in a high-temperature sulphide mineral termed Monosulphide Solid Solution (MSS), which converted to pyrrhotite, pentlandite and chalcopyrite as it cooled. PGE may be hosted in chalcopyrite or pentlandite, but they may
01-04-2000· The same may apply to Bi and Te. As Pt, Au, Bi and Te are not usually metals in solid solution in chalcopyrite, a subsolidus exsolution origin seems rather unlikely. For the Os–Ir–Pt inclusions we can find arguments both in favour of and against an exsolution origin.

20-04-2017· Chalcopyrite is a brassy yellow mineral with the chemical composition CuFeS2, or copper iron sulfide. It is found in most sulfide mineral deposits around the world. Chalcopyrite loses its surface metallic luster and brass-yellow color when it weathers, changing to a dull, gray-green color.
Chalkopyrit, veraltet auch als Kupferkies, Gelbkies, pyrites aureo colore oder geelkis bekannt, ist ein sehr häufig anzutreffendes Mineral aus der Mineralklasse der „Sulfide und Sulfosalze" mit der chemischen Formel CuFeS 2.Die Verbindung besteht also aus je einem Teil Kupfer und Eisen sowie zwei Teilen Schwefel und ist damit chemisch gesehen ein Kupfer-Eisen-Sulfid.
