Chalcopyrite (/ ˌkælkəˈpaɪˌraɪt, - koʊ -/ [7][8] 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.

2019年5月2日 · Chalcopyrite is also known as Peacock Ore because of its lovely iridescent green, blue, pink, purple, and gold colors that resemble the feathers of a peacock. The colors of Chalcopyrite come from the oxidation of copper and iron in the crystal. It’s a common mineral that can be found in most sulfide deposits.

Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS 2. It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years. The surface of chalcopyrite loses its metallic luster and brass-yellow color upon weathering.

2023年9月5日 · Chalcopyrite is a mineral and ore of copper. Its chemical composition is CuFeS2, meaning it contains copper (Cu), iron (Fe), and sulfur (S). Chalcopyrite is one of the most important copper ores and is widely distributed in various geological environments. It is often found in association with other sulfide minerals.

Brass yellow, often with an iridescent tarnish. Named in 1725 by Johann Friedrich Henckel from the Greek "chalkos", copper, and "pyrites", strike fire. Chalcopyrite Group. Chalcopyrite-Eskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in …

Chalcopyrite, the most common copper mineral, a copper and iron sulfide, and a very important copper ore. It typically occurs in ore veins deposited at medium and high temperatures, as in Río Tinto, Spain; Ani, Japan; Butte, Mont.; and Joplin, Mo. Chalcopyrite (Cu2Fe2S4) is …

Chalcopyrite is easily the most widespread copper-bearing mineral. A common mineral found in almost all sulfide deposits, chalcopyrite usually occurs in medium-temperature and high-temperature hydrothermal veins in igneous rocks or metamorphosed igneous rocks.

2023年4月9日 · Chalcopyrite is a naturally occurring mineral composed of copper, iron, and sulfur. Its chemical formula is CuFeS2, and it has a bright yellow color with iridescent purple, blue, and green hues. Chalcopyrite is commonly called peacock ore because of its metallic luster and rainbow-like colors.

Chalcopyrite is an important ore of copper found in a wide range of hydrothermal environments. It is often associated with sphalerite and galena. It oxidizes to form copper minerals such as malachite, azurite, cuprite and tenorite.

2023年7月13日 · Chalcopyrite usually occurs in anhedral masses or aggregates of variable granulometry, frequently as vein filling or disseminated. Also in stratiform concentrations with varied morphologies, laminar, massive, pseudomorph (by replacement) and collomorph. It acquires granoblastic texture in metamorphic contexts.
