Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals that occur in deposits large enough to mine.

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.

Bornite has a brown to copper-red color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places. Its striking iridescence gives it the nickname peacock copper or peacock ore. Mineralogy. Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.

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 ...

Chalcopyrite is a beautiful mineral, with good crystals being fairly common. It is also readily available, with quality specimens being surprisingly affordable. "Peacock Ore" which is sold to many amateur mineral collectors often as a variety of Bornite, is in fact almost always Chalcopyrite treated with acid to produce an iridescent tarnish ...

Chalcanthite is an important ore of copper in areas where it occurs in relative abundance, such as in Chile and Spain. It is also used as a root killer in sewer pipes by flushing Chalcanthite pellets down the toilet. Specimens are popular among collectors, and the synthetically grown crystals are often sold to unwary collectors.

Copper is a malleable, ductile reddish metal, and is one of only two strongly colored metals (gold being the other). Copper is a stable metal largely unaffected by water and air, although carbon dioxide will react with the surface of pure copper to form greenish copper carbonate.

Associated with various copper minerals, most commonly with the oxidized ores, cuprite, malachite and azurite. Most of the copper of commerce is obtained from one or the other of its sulfides. Some, however, is found as the native metal. Copper, often contains small amounts of silver, bismuth, mercury, etc.

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.

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.
