copper sulfide uses

One typical series of reactions that occur under oxidizing conditions and at high temperatures is shown below: FIGURE 15.4. EC#: 215-271-2. Fume cupboard, Bunsen burner, retort stand, boss and clamp (steel/iron), heat-proof mat and tongs; K. NowińskaA. Antifungal agent for topical use 4. The copper ions are distributed in a complicated manner over interstitial sites with both trigonal as well as distorted tetrahedral coordination and are rather mobile. In electroplating processes. Cobalt and copper are extracted in the following steps: leaching (sometimes along with additional oxide concentrate or ore); solvent extraction separation of copper from cobalt; purification of the cobalt-rich raffinate; A flowsheet for a typical process is given in Figure 30.7 and operating details are given in Tables 30.2–30.6. Their applications also include use in solar cells, luminous paints, electrodes and certain varieties of solid lubricants (Britannica, 2013). In addition, the majority of its members are semiconductors. Both minerals and synthetic materials comprise these compounds. Copper sulfate solutions may serve as an antiseptic and as a source for depositing copper on metals. /Anemia was able to be corrected/ by the addition to the diet of ash from animal or vegetable sources. The equilibrium diagrams of the Cu–S–Cl–H2O system at temperatures of 25, 100 and 150 °C are shown in Fig. Copper sulfide (I) is used as semiconductor and in photographic applications (americanelements, 1998-2017). COPPER SULFIDE . 8. Cooled roaster calcine (~75°C) is leached in aqueous sulfuric acid solution to give a leach sulfate solution of ~22 g/L Cu and 7 g/L Co. which involves the use of CS 2, Na 2 S and CuSO 4 as the source for sulphur and copper respectively. Copper sulfate helps in eradicating snails that harbor the parasite responsible for … Copper sulfate is an inorganic compound made by combining two elements, sulfur and copper. The estimated flotation stage recoveries and the feed mass flow rates are given in Table 1. Note the roasting temperature of 695–705°C. The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper that is cast into slab-like anodes. Some copper sulfides are economically important ores. A variety of fibres have been used including nylon, polyester, wool and acrylic for antistatic applications such as carpets. INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. The principal difference lies in what occurs at the anodes: oxygen evolution at the electrowinning anodes, dissolution of copper (the reverse of reaction 1) at the electrorefining anodes. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. It has a narrow range of stoichiometry ranging from Cu1.997S to Cu2.000S. Different stoichiometric compositions can be obtained by changing the redox atmosphere of the synthetic environment. The blood is teste… A good example is a 2009 study of the ternary compound CuCo2S4[14] (a spinel mineral known as carrollite) that "was undertaken primarily to establish unequivocally the oxidation state of the Cu in the mineral" and concluded "that the experimental and simulated Cu L2,3 absorption spectra established an unequivocal oxidation state of CuI in the carrollite bulk". Other leaching methods include ammonia leaching, which is used for certain copper oxide ores. Oxidation of iron impurities also occurs at the anodes to produce ferric and ferrous ions in solution. Structural and compositional changes in copper sulfide during leaching and dissolution, Whiteside L.S, Goble R.J, The Canadian Mineralogist; (1986);. Common Names and Synonyms: Cuprous sulfide. Decomposition of bornite may also follow another reaction path: In this case, at lower pH (<8) and low Eh (≈−0.40…−0.35) H2SO3 is formed, where sulfur is oxidized from S2− (in bornite) to S4+ (in H2SO3), and further decomposition follows: Copper, for its part, is reduced (bornite contains both Cu2+ and Cu+) to Cu+, whereas iron does not change its valence, as Fe2+ ions are formed. DATE OF LAST REVISION: 07/09/15. The anodes are electrolytically refined in cells sketched in Fig. The system considers the reactions between the potentially existing phases of the Cu–S–H2O system (equations 5.185–5.208) and ions and substances containing chlorine, Table 5.8. Experimental procedure involves the reaction of 15 ml Triton X-100, 25 ml Most of the copper ores mined today are oxide or sulfide ores. On the other hand, copper (II) sulfide finds applications in solar cells, superionic conductors, photodetectors, electroconductive electrodes, photothermal conversion devices, microwave protective coating, active radio wave absorbers, gas sensors and radiation polarizer… Pourbaix diagram of the Cu–Fe–S–O–H2O system at 25 °C. Estimated flotation stage recoveries, feed mass flow rates and global recovery goals. The copper sulfate test is a visual method of determining the existence of free iron in specifically stainless steel. Industrial Cobalt Electrowinning Details∗. Figure 8.

CAS Number: 1317-40-4 / EC Number: 215-271-2 Company: Angstrom Sciences, Inc. Further evidence that the assignment of the so-called "valence hole" should be to the S2 units in these two formulae is the length of the S-S bonds, which are significantly shorter in CuS (0.207 nm) and CuS2 (0.203 nm) than in the "classical" disulfide Fe2+(S2)2− (0.218 nm). In comparison with the previously discussed diagrams, the diagrams of the Cu–S–Cl–H2O system are characterised by the presence of a large area of stability of univalent chlorine complexes of copper. A decrease of the total concentration of copper below 0.01 M results in the area of stability of CuCl2−(aq). 5.15. SAFETY DATA SHEET . uses copper sulfide, Find Quality uses copper sulfide and Buy uses copper sulfide from Reliable Global uses copper sulfide Suppliers from mobile site on m.alibaba.com This substance is mainly used as a pesticide in agricultural or nonagricultural practices to help eliminate bacteria, algae, roots, plants, snails and fungi. Oxide concentrate: 20% Cu, 1.3% Co (60% Cu recovery, 40% Co recovery). Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution (Sherrit, Pavlides, & Weekes, 2005). Copper /is/ essential for erythropoiesis in rats fed a milk-based diet. TABLE 30.5. Copper sulfide is a crystalline solid used as a semiconductor and in photo optic applications. There is a resemblance to the cell of Fig. Table 1. Interspersed copper anodes and cathodes are suspended in an electrolyte. Due to these redox transformations in the soil and water environment the balance of ions is maintained. In this example, the production of a copper concentrate is investigated. This table describes concentrate production. Evans, in Reference Module in Materials Science and Materials Engineering, 2016. Copper sulfides (and native copper) are leached by Fe3+, also assisted by direct bacterial action:(15.11a)2FeS2+7O2+2H2O→2Fe2++2SO42−+2H2SO4(15.11b)O2+4Fe2++4SO42−+2H2SO4→4Fe3++6SO42−+2H2O(15.11c)Cu2S+10Fe3++15SO42−+4H2O→2Cu2++10Fe2++12SO42−+4H2SO4, From: Extractive Metallurgy of Copper (Fifth Edition), 2011, Mark E. Schlesinger, ... William G. Davenport, in Extractive Metallurgy of Copper (Fifth Edition), 2011. Treatment of copper deficiency 5. Finally, in relation to the study of the RVO and PAX collector mixtures, it was found that a mixture of 60 g/t of RVO and 40 g/t of PAX in the absence of foaming agent presented the best results in terms of copper recovery (98.66%) and the selectivity index with respect to pyrite (2.88) and silica (14.65), improving PAX selectivity and recovery compared to the use of RVO as the only collector. The starting solution is solvent extraction raffinate, containing approximately 7 g/L Co. Advance electrolyte is prepared from the raffinate by purification, precipitation of cobalt hydroxide then redissolution of the cobalt hydroxide in recycle spent electrolyte from cobalt sulfate electrowinning. Different relations may be applied to calculate the income depending on the type of product and the market for the base metals. Conductivities range from (10−10…10−8 [Ω cm]−1) with nylon and polyester. Although many textbooks (e.g. Roasting of Cobalt–Copper Sulfide Concentrates to Soluble Sulfate Calcine. New Window. The anodes are dissolved to the point at which they start to fall apart. Copper sulfide ores must be concentrated before they can be economically transported and smelted. Precious metal impurities in the anode are not oxidized at the anode potentials employed, but fall to the bottom of the cell as an “anode slime” which is occasionally harvested from the cells and sent for recovery of precious metals. The residuum is removed from the cell and re-melted/cast into fresh anodes and these are placed in the cell. Section 1: Identification . TABLE 30.2. 3. This division of copper into species depends not only on temperature but also on the total activity of copper in the solution. It is used to keep algal blooms away, especially from the swimming pools and water reservoirs. Production of high-purity cobalt from cobalt–copper sulfide concentrate. It is designed to give soluble sulfate calcine rather that insoluble oxide calcine. This is cast into slab-like anodes. With increasing temperature the amount of the copper complexes in the system varies. The maximum number of stages was determined based on the estimated stage recoveries and the bounds on global recoveries, which resulted in three cleaner stages and one scavenger stage. Table 5.8. In dump leaching, the pH of the solution is maintained between 1.5 and 3.0, partly to preserve bacteria that promote and accelerate the oxidation of purity and copper sulfate minerals and also to prevent hydrolysis of iron salts. Sulfide Simultaneously, as a result of reaction (3), Cu (which in bornite can have the valence of 2+ or 1+) is reduced to metallic copper. Substances containing chlorine in the equilibrium system Cu-S-Cl-H2O. Typical operating conditions for copper electrorefining cells are (Habashi 1998): 100–200 Amps m−2 at a cell voltage of 0.3 V with an electrolyte of 40 g L−1 of copper and 150–200 g l of sulfuric acid. Both are constructed of acid resistant concrete and contain cathodes (connected in parallel) interleaved with anodes (also connected in parallel). Copper sulfide is a copper sulfide, a chemical compound of copper and sulfur. Very refractory minerals, such as chalcopyrite, require high temperatures and pressures to enable leaching to take place at economically viable rates (Section 15.7). 15.4. 8. In contrast, recycling copper typically uses 90% less energy. After mineralogical examination, we decided to divide the ore into four species for characterization: Cp (100% CuFeS2), CpPy (95% CuFeS2 - 5% FeS2), PyAs (70% FeS2 - 30% AsFeS), and Sc (100% SiO2). Antiseptic agent 2. Felipe D. Sepulveda, ... Edelmira D. Gálvez, in Computer Aided Chemical Engineering, 2012. The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. CU-FES-02-C , CU-FES-03-C , CU-FES-04-C , CU-FES-05-C CAS #: 1308-56-1 Relevant identified uses of the substance: Scientific research and development Supplier details: American Elements 10884 Weyburn Ave. The resulting Fe2+ is reoxidized to Fe3+ by O2. Principal impurities are iron and precious metals (gold and silver). J.W. It is found in nature as the mineral chalcocite. Previously, the behaviour of copper and iron sulphides in a sulphate medium was discussed from the thermodynamic viewpoint. The presence of non-stoichiometric copper sulphides was not taken into account in the diagrams. Principal impurities are iron and precious metals (gold and silver). SECTION 1. Precipitation with MgO and redissolution produces cobalt-rich, high-purity electrolyte. Depending on their composition, these copper sulfides are either semiconductors or metallic conductors. Species diagrams should be applied to these purposes, as discussed later. 5.14. If at room temperature the highest stability was shown by CuCl32−(aq), at higher temperatures it is CuCl2−(aq). The input is high-purity cobalt sulfate electrolyte ~20 g/L Co2+. Whatever their source, copper sulfides vary widely in composition with 0.5 ≤ Cu/S ≤ 2, including numerous non-stoichiometric compounds. Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite). Therefore, this group of copper sulfides shows ionic conductivity at slightly elevated temperatures. Copper sulfate is used in the preparation of Paris green, to kill mosquito larvae that cause malaria. Eng.,19', 204 (2006). Certain metal salts like copper sulphide and copper iodide are predominantly utilised for electrically conductive coatings on fibres, as they are easily processable using ordinary textile technology. Dyes - Copper sulfate can also be used as a mordant in vegetable dyeing. Adjacent cells are connected in series and several hundred cells would be contained in a typical electrorefining tankhouse. Sketch of a copper electrorefining cell from (Evans and DeJonghe 2002). Alternatively stainless steel cathode blanks are used as described above under Copper Electrowinning. These methods are called leach-precipitation-flotation and are applied to mixed sulfide ores. By continuing you agree to the use of cookies. Leaching systems using copper chloride as an oxidation agent are also being introduced. Copper sulfate CuSO 4 found its application in various fields of human activity. Deposition of slags of the presented mineral composition in the environment may produce certain effects in surface and/or ground waters. Seek medical attention. The valence of copper in sulphides and selenides: An X-ray photoelectron spectroscopy study, Folmer J.C.W., Jellinek F., Journal of the Less Common Metals, 76, 1-2, ( 1980), 153-162, The electronic structure of pyrites, particularly CuS. Column flotation cleaner cells are particularly effective at giving a high Cu grade in the concentrate. This stability is confirmed by Eh–pH diagrams (Pourbaix, 1978) plotted for a Cu–Fe–S–H2O system for the following conditions: temperatures typical for the climate prevailing in Poland (−5 and +25 °C). Etching - Copper sulfate is also used to etch zinc plates for intaglio printmaking. Most minerals require the application of both an acidic environment and an oxidizing agent to leach copper as Cu2+. Its crystal structure is analogous to that of pyrite, with all sulfur atoms occurring as S-S units. Extraction of Cobalt and Copper from Sulfide and Mixed Sulfide-oxide Ores. Product Name: Copper Sulfide . In order to determine these effects, detailed simulations of the behavior of the main mineral component of the metallic inclusions in the slag, i.e., cubanite, were carried out. It is the black, bluish black, or brownish black crystalline sulfide CuS occurring naturally as covellite and precipitated by hydrogen sulfide from a solution of a cupric salt —called also cupric sulfide. Copper sulfide finds applications in the following: Solar cells; Superionic conductors; Photodetectors; Electroconductive electrodes; Photothermal conversion devices; Microwave shielding coating; Active absorbents of radio waves; Gas sensors; Polarizers of infrared radiation; Chemical Properties. Siew Wei Goh, Buckley A.N., Lamb R.N: Copper(II) sulfide?, Min. 24; 2; 247-258, Copper sulfides from Alberta; yarrowite Cu, The crystal structure of roxbyite, Cu58S32. It often highlights the green tints of the specific dyes. The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. 7. 5 °C – pH=5.9÷10.3 (∆pH=4.4); Eh=−0.58÷−0,30 (∆Eh=0.28). Consequently, the stability region of bornite in the summer season (25 °C) will be narrower than in the winter season, as the ranges ∆pH and ∆Eh decrease with rising temperature in the series of −5, 5 and 25 °C. Fig. E–pH diagram of the Cu-S-Cl-H2O system for 100 °C, the activity of sulphur-containing substances of 10−1 M, the activity of copper-containing substances of 10−1 and 10−2 M at the unit activity of chlorides. The chemical properties of copper sulfide are provided in the table below: Both minerals and synthetic materials comprise these compounds. For instance, anhydrous copper sulfate can be used as a dehumidifying agent. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The copper sulfide is oxidized by Fe3+. 5.14. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H 2 S, is bubbled through solutions of Cu(II) salts. Copper sulfate is an inorganic compound that combines sulfur with copper that has been registered for use in the United States since 1956. Typical concentrate grades are 30% Cu (higher with chalcocite, bornite, and native copper mineralization). Frank K. Crundwell, ... William G. Davenport, in Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals, 2011. It has the chemical compound Cu2S. Copper sulfate is used to test blood for anemia.
