One of the most important ores of the copper mineral is chalcocite, and compared to other ores it has the most benefits. Chalcocite has a content of high copper, and copper can be easily separated from sulfur. Chalcocite is very scarce, and it is formed from the mineral's alteration of primary copper attacked by oxygen. The color of chalcocite may be black or blackish-grey, with a grayish ...

Chalcocite. Definition. Chalcocite (Cu 2 S) is a lead-grey or black mineral, found as a copper ore or in veins. It is a source of copper. It is most commonly found as a supergene mineral in the enriched zones of sulfide deposits. It is also occurs in hydrothermal veins. It has a hardness of 2½ – 3 on the Mohs scale.
CHALCOCITE: Chalcocite, or copper sulfide, is a secondary mineral that forms mainly below the oxidation zones of copper deposits. It is a major ore of copper and is collected for the rarity of its crystals, metallic luster, and subtle, blue-purple iridescence.
A copper ore has a head grade of 4% copper (Cu) and 10% iron (Fe). The ore is a sulphide, with chalcocite and pyrite the minerals present. Assuming that the remainder of the ore is pure silica: i) Calculate the weight percentage of sulphur in the ore.
Chalcocite is an important copper ore. It has a high copper content and the process of extracting the copper from the sulfur in Chalcocite is relatively easily. Chalcocite is also an important collector's mineral, and good crystals command very high prices.
Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S). The concentrations of these minerals in an ore body are low. Typical copper ores contain from 0.5% Cu (open-pit mines) to 1−2% Cu (underground mines).
Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
Chalcocite definition, a common mineral, cuprous sulfide, Cu2S: an important ore of copper. See more.
Copper can be extracted from various types of ores, most of which belong to the sulfidic ores such as chalcopyrite, bornite, covellite, digenite and chalcocite. Chalcopyrite is the most common copper-bearing mineral and accounts for approxi-mately 70% of the copper deposits in the world.1 At present,
Copper can be found in more than 200 minerals, but only about 10% of this occurs in the form of sulphide minerals (e.g., chalcopyrite, bornite and chalcocite) or oxidized minerals (e.g., cuprite), which are of significance as copper ores (Lossin, 2001).Depending mainly on the ore type, as well as the geographical, economic and environmental considerations, copper can be extracted through:

Chalcocite, sulfide mineral that is one of the most important ores of copper.Valuable occurrences include deposits of sulfide minerals at Ely, Nev., and Morenci, Ariz., where other components of the original rock have been dissolved away; it is also found with bornite in the sulfide veins of Tsumeb, Namibia, and Butte, Mont. For detailed physical properties, see sulfide mineral (table).
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.
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 …
"Peacock Ore" Bornite is easily recognized because it tarnishes to iridescent shades of blue, purple, red, green and yellow. It is commonly called "peacock ore" or "purple copper ore" after these iridescent colors. Upon surface exposure, bornite will weather to chalcocite or other copper minerals.
