Chalcopyrite, CuFeS 2, is the dominant copper mineral in these ores, with small amounts of another copper mineral, cubanite, CuFe 2 S 3.Some gold, silver, and the six platinum-group metals also are present, and their recovery is important. Cobalt, selenium, tellurium, and sulfur may be recovered…
Transcribed image text: 12 Question (3 points) a See page 111 "Native," or elemental copper can be found in nature, but most copper is mined as oxide or sulfide minerals. Chalcopyrite (CuFeS2) is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide.

Copper is found in many minerals that occur in deposits large enough to mine. These include: azurite, malachite, chalcocite, acantite, chalcopyrite and bornite. Most copper comes from chalcopyrite. The world's leading producer of copper is Chile, followed by the U.S. and Peru.
Chalcopyrite is essentially unleached under the mild oxidizing conditions of heap leaching (very slow leach kinetics). It can, however, be leached under oxidizing conditions at elevated temperatures or by microbial leaching under low-potential conditions (Gericke, Govender, & Pinches, 2010).This has led to extensive study into leaching of chalcopyrite concentrates as an alternative to smelting.
Best Answer. The chemical formula for Chalcopyrite is CuFeS 2. This compound corresponds to a molecular mass of 183.54. The distribution of mass for this compound is. Iron Fe 55.845 (1) 30.430%. Copper Cu 63.546 (1) 34.626%. Sulfur S 32.065 (2) 34.944%. Cu – copper represents 34.626% of the total mass of this compound.
Chalcopyrite Properties. 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 derived from chalcos (Greek for copper) and pyrite (an iron sulfide). photos
The most common source of copper (Cu) is the mineral chalcopyrite (CuFeS2). How many kilograms of chalcopyrite must be mined to obtain 450. g of pure Cu? Science. 1. Which of the following best describes an example of land reclamation? A. After an area is mined for copper, the soil is replaced and new plants are planted. B.
Mining also occurs in Mexico just south of the US border and Baja California. Other locations include Oklahoma, Missouri, Colorado, New York, New Jersey and Pennsylvania. (5 & 7) Economic Uses: Chalcopyrite is polished into cheap jewelry such as pendants and beads (12). For instance, chalcopyrite can be formed into cabochons, which are smooth ...
Chalcopyrite. Un article de Wikipédia, l'encyclopédie libre. 2. Sulfures, incluant séléniures et tellurures. Unités du SI & CNTP, sauf indication contraire. La chalcopyrite est une espèce minérale composée de sulfure double (35 % massique), de cuivre (34,5 %) et de fer (30,5 %), de formule CuFeS 2.
Chalcopyrite. Named from the Greek words for "copper," chalkos, and for "fire," pyr, likely in reference to the color of the mineral as well as its copper content. While similar to pyrite, Chalcopyrite is distinguished physically and visually as being softer and a brighter yellow with a green hue when wet.
Part 2 (1 point) How much chalcopyrite had to be mined to produce 100 pennies if reaction I had a percent yield of 72.00% and all other reaction steps had yield of ? 1442.46g CuFes Part 3 (1 point) How much chalcopyrite had be mined to produce 100 pennies if each reaction involving copper proceeded in 72.00 % yield? g CuFeS2.
The minerals commonly associated with chalcopyrite include pyrite, bornite, chalcocite, galena, and sphalerite. Uses Area. The most important use of chalcopyrite is an ore of copper for five thousand years. Some chalcopyrite ores consist of some amount of zinc substituting for iron. Some chalcopyrite ores consist of sufficient mining silver or ...
As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using ...

Chalcopyrite - the Peacock Ore. 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.
Chalcopyrite is famously minded at Olympic Dam, one of the largest mines in the world.
"0.938 kg CuFeS"_2" is needed to obtain 325 g of pure "Cu". The chemical formula for chalcopyrite, "CuFeS"_2 indicates that each mole of the compound contains one mole of copper. The following represents the method that will be used to determine how many kg of "CuFeS"_2 must be mined to obtain "325g Cu". color(red)("mass Cu"rarrcolor(blue)("mole Cu"rarrcolor(green)("mol …
Chalcopyrite. Chalcopyrite is an Ore, it must be smelted in an Ore Smelter to extract Bar of Copper or Bar of Cast Iron with 8% and 4% respectively chance (% showed with all mining skills), otherwise it smelts into Slag . Ore is a type of Stone, so it can also be used as pavement and to build with. Chalcopyrite looks like this inside the game:
Also, the conversion of chalcopyrite is an important process in secondary mineralization during supergene enrichment, and secondary mineralization may occur during long cycles of dump leaching. In deep solution mining, secondary reactions undoubtedly will assume an important role.
Chalcopyrite is a very common mineral and the major ore of copper occurring as massive mineral deposits to veins to disseminated crystals in the porphyry copper deposits so important in the U.S. Massive Bornite and chalcopyrite, Flambeau Mine, Rusk County, Wisconsin. In fact, it is often called "peacock ore!"
Chalcopyrite occurs with lead and zinc ores in the Tri-State district in Cherokee County. Although chalcopyrite is mined throughout the world as a copper ore, commercial quantities of the mineral are not known in Kansas. Greenockite (hardness 3-3 1/2) Greenockite, …
Mined chalcopyrite can be an appropriate photo-Fenton-like catalyst in the degradation of phenolic compounds found in OMW because it can provide a high TOC removal, proper acidic pH conditions, low leaching of iron species and spontaneous formation of a small amount of H 2 O 2. However, the catalyst stability must be improved to minimize the ...
Chalcopyrite and its associated minerals were taken from the Dongchuan copper mine in Yunnan, China. The impurities and gangue minerals were manually removed to prepare single mineral of high-purity chalcopyrite. The prepared sample was soaked in 1% sulfuric acid solution for 12 h, and then naturally dried after repeated rinsing with deionized water.
