The chemical compound CuSO 4 has a wide range of applications. Some of these uses are listed below. The pentahydrate of this compound, CuSO 4 .5H 2 O is used as a fungicide due to its ability to kill several fungi. Copper sulfate is used in Benedict's solution and in Fehling's solution, which is used in testing for reducing sugars.
All III12 and lI2 chalcopy- rites together with CuFeS2 are listed in table 2. The chalcopyrites for which the modifications are known up to the melting point are collected in fig. 5, where along the horizontal axis the axial ratio c/a of the chnicopyrite unit cell is plotted, versus the type of anion along the vertical axis.
tal point of view, this is a questionable produc-tion route. Several different processes can be used for copper production. The traditional process is based on roasting, smelting in reverbatory fur-naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con-verting for production of blister copper, which is
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 melting point of CuFeS2 was not determined here, but Schlegel and Schtiller (7) obtained a value of 950~ did additions of Se and Cu. This behavior suggests that an appreciable range of composition is possible; however, infrared transmissions of samples of differing lattice con- stant were very similar.

Relative atomic mass: 63.546 (3) Copper has been known since ancient times. The origin of the name comes from the Latin word cuprum meaning the island of Cyprus famed for its copper mines. It is a malleable, ductile, reddish-brown metal, resistant to air and water. Exposed surfaces form greenish carbonate film. Pure copper occurs rarely in nature.
copper (Cu), chemical element, a reddish, extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat. Copper is found in the free metallic state in nature. This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans.

Iron pyrite (FeS 2) has attracted significant attention as a promising inorganic material in various applications, such as electrode materials for high-energy batteries, medical diagnostics, semiconductor materials, and photovoltaic solar cells.In this study, we characterized the crystalline structure and magnetic properties of FeS 2 using X-ray diffraction (XRD), vibrating …
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
It is necessary to know the values of the thermal conductivity coefficient of a semiconductor material to assess the possibility of its application as a thermoelectric. The thermal conductivity of natural minerals of galena (PbS), chalcopyrite (CuFeS2), and ZnS ceramics was studied using the absolute stationary method of longitudinal heat flux in the range of 50-300 K.
As the melting points of Cu and Fe are high, the main synthesis approach to obtain CuFeS 2 relies on high-temperature melting combined with annealing and this approach requires considerable time ...
The temperatures of these two zones were regulated independently, and the temperature of the zone with a quartz crucible exceeded the melting point of the compound by 20 K. The samples of CuFeS 2− δ were single-phase and they crystallized in the tetragonal structure with the lattice constants a = 5.287(5) Å and c = 10.423(10) Å.

The iron oxides interact with silica and other oxide materials to form the slag which reduce the melting point of reaction mix. $$ce{Cu2O + FeS <=> Cu2S + FeO}$$ $$ce{FeO + SiO2 → underset{slag}{FeO.SiO2}}$$ The matte contains 30–70% copper, primarily as copper sulfide, as well as iron sulfide.
Smelting is the process of taking the copper concentrate (CuFeS2) and reacting it with SiO2, and O2 to produce slag (waste), copper matte and sulphur dioxide (gas) Too much silica results in the copper being oxidised Too quickly. The matte copper is further treated in a copper converter. Original Description. Copper Processing.
