Appearance

Wisconsin Geological amp; Natural History Survey 187; Chalcocite

Description Chalcocite is formed either as a primary vein mineral or, more typically, in supergene deposits where it forms as a result of the redeposition of copper from the breakdown of minerals such as chalcopyrite or bornite.

Copper Minerals Education Coalition

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. These include azurite, malachite, chalcocite

Chalcanthite The blue mineral Chalcanthite information

The Mineral chalcanthite Natural Chalcanthite crystals are very rare in nature. Wellformed crystals are easily grown synthetically from copper sulfate solutions. This can be done by dissolving a readily available chemical salt called copper sulfate, and then letting the water evaporate.

Covellite

Covellite (also known as covelline) is a rare copper sulfide mineral with the formula CuS. This indigo blue mineral is commonly a secondary mineral in limited abundance and although it is not an important ore of copper itself, it is well known to mineral collectors.

CHALCOCITE (Copper Sulfide)

Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur.

Chalcocite Geology Wiki Fandom

Chalcocite is commonly found as a lead color to a dark black color, and it usually grows in many different types of sedimentary rocks. It is a very commonly mined copper mineral, and when growing with different rocks, it can sometimes change the structure of the rock/mineral.

Chalcocite (Cu 2 S) belongs to a group of sulfide minerals formed at relatively low temperatures (see also argentite). Chalcocite alters to native copper and other copper ores. Chalcocite alters to native copper and other copper ores.

Chalcocite Mineralogy4Kids

Once of the most important copperore minerals, chalcocite occurs as a secondary mineral in or near the oxidized zone of copper sulfide deposits. Under surface conditions, the primary copper sulfides are oxidized, the soluble sulfates formed move downward reacting to form chalcocite, and thus, enriching the ore in copper.

Spionokopite, Cu 39 S 28 Frenzel [41], found that the blue covellite, formed by leaching of chalcocite, may have an excess of copper up to the composition Cu 14 S. However, at a later stage Goble [31] defined new minerals, spionokopite and yarrowite. Spionokopite, found in nature as a mineral, has the composition in the range between Cu 132 S

Chalcopyrite Mineral Uses and Properties

The most significant chalcopyrite deposits to be mined are hydrothermal in origin. In these, some chalcopyrite occurs in veins and some replaces country rock. Associated ore minerals include pyrite, sphalerite, bornite, galena, and chalcocite. Chalcopyrite serves as the copper source for many secondary mineral deposits.
