    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.

  2. Apr 29, 2018 · 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.

  3. 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 igneous rocks.

  4. What is Chalcopyrite? 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. It tarnishes to a ...

  5. Numerous localities world wide. The most economically important mineral in porphyry copper deposits. Link to MinDat.org Location Data. Name Origin: From the Greek, chalkos, "copper" hence "Copper Pyrite." Name Pronunciation: Chalcopyrite + Pronunciation. Synonym: ICSD 2518.

  6. Chalcopyrite is a copper iron sulfide (CuFeS 2) mineral with a brassy to golden yellow color (Fig. 1.36). Chalcopyrite contains 34.5% Cu, 30.5% Fe, and 35.0% S. The mineral is the principal source of copper metal, and one of the major source of sulfur. The mineral also contains traces of elements of gold and nickel and recovered in refinery.

  7. The Mineral chalcopyrite. Chalcopyrite has a golden yellow color, which often resembles Gold. However, its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it. Chalcopyrite is a beautiful mineral, with good crystals being fairly common.

  8. 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 a member of a group of.

    Chalcopyrite is a striking, bright yellow, metallic mineral that occurs in nearly all sulfide deposits. Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS2), with pyrite (FeS2), but the two can be distinguished by their relative hardness and chalcopyrite’s iridescent tarnish.

  10. Nov 19, 2018 · Chalcopyrite is the most important copper ore, and it is the primary source of many popular secondary copper minerals. It can occur in a variety of environments and forms, from hydrothermal veins to sedimentary layers. Nice chalcopyrite crystals are highly sought after by collectors.
