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.
Bornite commonly occurs with other copper sulphide minerals such as chalcocite and weathers, or “oxidizes”, to malachite. Chalcopyrite is the most common ore mineral for copper. Chalco comes from the Greek word chalko, meaning copper. Chalcopyrite is commonly found in sulphide deposits in most ore-forming environments.
Bornite is an ore mineral of copper, and is known for its iridescent tarnish. "Peacock Ore", which is sold to amateur mineral collectors and tourists, is often labeled as a variety of Bornite.However, most Peacock Ore in reality is Chalcopyrite treated with acid, which produces a strongly-colored iridescent tarnish.Bornite is named for Ignatius von Born, an Austrian mineralogist and
Copper or The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S) covellite (CuS) bornite (Cu5FeS4) tetrahedrite ((Cu Fe)12Sb4S13) and enargite (Cu3AsS4) The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs A typical copper sulphide ore

Upon surface exposure, bornite will weather to chalcocite or other copper minerals. Bornite is a popular and fast-selling mineral specimen at museums, mineral shows, and tourist shops. However, some material sold as "peacock ore" has a tarnish with spectacular colors greatly exceeding what is expected on bornite.

Associated ore minerals include pyrite, sphalerite, bornite, galena, and chalcocite. Chalcopyrite serves as the copper source for many secondary mineral deposits. Copper is removed from chalcopyrite by weathering or solution, transported a short distance, then redeposited as secondary sulfide, oxide, or carbonate minerals.

copper ores chalcopyrite,bornite,chalcocite. copper ore chalcocite bornite. Manufacture of copper About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral for example chalcopyrite (CuFeS 2) (the most abundant copper ore) bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S) These ores contain typically only about Get Info】
ORIGIN OF ORE TEXTURES: PORPHYRY COPPER DEPOSITS. Apr 23, 2010 By last count, there are more than 100 porphyry copper deposits in North of chalcopyrite and bornite responsible for the copper ore grade of 0.75%, being mined, lattice intergrowths of bornite-chalcocite are most common.get price
The chalcopyrite-pyrite mixed type ore and chalcopyrite-bornite mixed type ore samples were obtained from Daye Mine of Hubei Province of China and Meizhou Mine of Guangdong province of China, respectively. X-ray diffraction (XRD) (Fig.1 (a) and (b)) indicated that the former mainly contained chalcopyrite and pyrite, the latter mainly contained
Peacock Ore, Bornite Healing Stones . Peacock Ore, also known as Bornite, is a copper mineral mined in Mexico. Known for its iridescent colors, it was nick-named peacock ore by early miners. This stone of happiness and joy will help you tune into positive forces in life and channel that energy to others.
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
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
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.
