Dyes - Copper sulfate can also be used as a mordant in vegetable dyeing. Principal impurities are iron and precious metals (gold and silver). 8. The issue of the valence of copper in sulfides (as well as selenides and tellurides) continues to be revisited in the literature. Interspersed copper anodes and cathodes are suspended in an electrolyte. CAS Number: 1317-40-4 / EC Number: 215-271-2 Company: Angstrom Sciences, Inc. Oxide concentrate: 20% Cu, 1.3% Co (60% Cu recovery, 40% Co recovery). 4 FIRST AID MEASURES. 15.4. Although many textbooks (e.g. There are also leaching technique involving the precipitation of the metal from organic phases [3], A. Harlin, M. Ferenets, in Intelligent Textiles and Clothing, 2006. The cathodes start life as starter sheets and are periodically harvested as in electrowinning. 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. [Cu] = 0.01 M; [Fe] = [S] = 0.1 M. (Peters, 1976). A typical structure is cell-core or side-by-side bi-component structure. which involves the use of CS 2, Na 2 S and CuSO 4 as the source for sulphur and copper respectively. Curing \"Proud Flesh\" on Horses. Common Names and Synonyms: Cuprous sulfide. Details of Industrial Leaching of Copper–Cobalt Sulfate Roaster Calcine, Figure 30.7∗. In addition to the iron sulphate, iron chloride is also used as an oxidation agent, especially because it is a far more efficient leaching agent than the sulphate. [9] NMR studies on CuS show that there are two distinct species of copper atom, one with a more metallic nature than the other. The anodes are electrolytically refined in cells sketched in Fig. Pourbaix diagram of the Cu–Fe–S–O–H2O system at 25 °C. In addition, the majority of its members are semiconductors. Alternatively stainless steel cathode blanks are used as described above under Copper Electrowinning. After mineralogical examination, we decided to divide the ore into four species for characterization: Cp (100% CuFeS 2 ), CpPy (95% CuFeS 2 - 5% FeS 2 ), PyAs (70% FeS 2 - 30% AsFeS), and Sc (100% SiO2). A glance at Table 1 shows that there is little tendency for the iron in the electrolyte to co-deposit with the copper; copper deposition is thermodynamically much more favorable. Copper sulfate is an eff… Product Name: Copper Sulfide . Ingredient: Copper (I) Sulfide. The data are approximate. Evans, in Reference Module in Materials Science and Materials Engineering, 2016. 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. 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. However, even though the use of seawater in mineral process Figure 8. 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. Major uses: Preparation of Bordeaux and Burgundy mixtures for use as fungicides: Manufacture of other copper fungicides such as copper-lime dust, tribasic: copper sulphate, copper carbonate and cuprous oxide: Manufacture of insecticides such as copper arsenite and Paris green: Control of fungus diseases (see Table B) Correction of copper deficiency in soils This is cast into slab-like anodes. Column flotation cleaner cells are particularly effective at giving a high Cu grade in the concentrate. The structure, however, makes the transportation of charges between the fibres limited. CuS is a moderate conductor of electricity. It destroys algae and bacteria caused by growing algae in swimming pools in addition to preventing athlete’s foot, a fungal infection that grows in between the toes in warm climates (such as an indoor swimming pool). Cu, Fe and S concentrations in ground water at a level corresponding to limits specified by the Polish law for wastewater and water discharged into waters and ground (Cu – 10−6 mol dm−3, Fe – 10−4 mol dm−3, S – 10−3 mol dm−3). Research done by Havlik (2008) and others (Peters, 1977) has demonstrated that cubanite is not stable in a hypergenic environment and in the presence of water and oxygen is converted at a fast rate into chalcopyrite according to reaction equation: whereas the formed chalcopyrite in the same environment will undergo further conversion into bornite according to reaction equation: Bornite is a more stable copper and iron sulphide in a hypergenic environment than cubanite and chalcopyrite. 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. 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. Etching - Copper sulfate is also used to etch zinc plates for intaglio printmaking. 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. Typical Cu sulfide recoveries to concentrate are 85–90%. Antifungal agent for topical use 4. Evans, in Encyclopedia of Materials: Science and Technology, 2003. Copper based nanoparticles have shown excellent anticancer activity as well as have been long used for radio-imaging. Stanislav S. Naboychenko, ... Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009. The naturally occurring mineral binary compounds of copper and sulfur are listed below. The anodes are dissolved to the point at which they start to fall apart. Species diagrams should be applied to these purposes, as discussed later. The copper content of the solution varies from less than 1 g/L to several grams per liter. In many cases, the copper sulfate test is used as a pass/fail examination of a passivation process on a part or stock material, but it can also be used as a test to determine if passivation is necessary in the first place. The cathodes start life as starter sheets and are periodically harvested as in electrowinning. TABLE 30.3. Flotation is commonly used to concentrate copper sulfide minerals, such as chalcopyrite (CuFeS2). The iceman's hair contained high levels of the toxin arsenic, which may indicate the man was exposed to the element during copper … It is designed to give soluble sulfate calcine rather that insoluble oxide calcine. New Window. Most of the copper ores mined today are oxide or sulfide ores. 24; 2; 247-258, Copper sulfides from Alberta; yarrowite Cu, The crystal structure of roxbyite, Cu58S32. 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. CAS#: 1317-40-4 %: 100. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H 2 S, is bubbled through solutions of Cu(II) salts. Otzi the Iceman (3300 BCE) was found with an axe that had a head consisting of nearly pure copper. A typical benefit of the solution is markedly textile-fibre-like properties with reasonable conductivity. In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "copper sulfides". Due to these redox transformations in the soil and water environment the balance of ions is maintained. 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 Substances containing chlorine in the equilibrium system Cu-S-Cl-H2O.

This division of copper into species depends not only on temperature but also on the total activity of copper in the solution. 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. SECTION 1. INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. It is found in nature as the mineral chalcocite. The product is electrowon cobalt metal, 99.65–99.7% Co. Cobalt recovery from concentrate to metal is ~62%. This substance is mainly used as a pesticide in agricultural or nonagricultural practices to help eliminate bacteria, algae, roots, plants, snails and fungi. Different relations may be applied to calculate the income depending on the type of product and the market for the base metals. 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). Fig. 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). If at room temperature the highest stability was shown by CuCl32−(aq), at higher temperatures it is CuCl2−(aq). For instance, anhydrous copper sulfate can be used as a dehumidifying agent. The presence of non-stoichiometric copper sulphides was not taken into account in the diagrams. Treatment of copper deficiency 5. 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. 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. We use cookies to help provide and enhance our service and tailor content and ads. General Measures: Remove patient from area of exposure. 8. At these concentrations of Cu, Fe, and S in ground water the stability regions of cubanite and chalcopyrite are nonexistent, which is accordant with reactions (1) and (2). 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. TABLE 30.4. Typical concentrate grades are 30% Cu (higher with chalcocite, bornite, and native copper mineralization). Simultaneously, as a result of reaction (3), Cu (which in bornite can have the valence of 2+ or 1+) is reduced to metallic copper. ∗(Adham et al., 2010). ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. The residuum is removed from the cell and re-melted/cast into fresh anodes and fresh anodes are placed in the cell. 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. Roasting of Cobalt–Copper Sulfide Concentrates to Soluble Sulfate Calcine. Copper monosulfide is a chemical compound of copper and sulfur.It was initially thought to occur in nature as the dark indigo blue mineral covellite.However, it was later shown to be rather a cuprous compound, formula Cu + 3 S(S 2). COPPER SULFIDE . The estimated flotation stage recoveries and the feed mass flow rates are given in Table 1. Table 1. Copper sulfide is a copper sulfide, a chemical compound of copper and sulfur. Typical operating conditions for copper electrorefining cells are (Habashi, 1998): 100–200 A m-2 at a cell voltage of 0.3 Vwith an electrolyte of 40 g l-1 of copper and 150–200 g l-1 of sulfuric acid. CAS#: 22205-45-4 %: 100. Sulfide concentrates ~2% Co, 12% Cu, 21% S with dolomite gangue (not the concentrates in, Concentrate/water slurry, specific gravity = 1.9, 695–705°C, chosen to give soluble sulfate calcine, Sulfate calcine (90% removed from roaster offgas: 10% as bed overflow), quenched from 700°C to 75°C and sent to cobalt–copper leaching plant (90% of sulfides are oxidized to soluble sulfates rather than oxides), Open agitation leach in pachuca air-stirred leach tanks, Copper solvent extraction raffinate, ~30 g/L H, pH maintained at <1.5 by adding fresh sulfuric acid, as needed, Sulfate leach solution 7 g/L Co, 22 g/L Cu, <50 ppm solids (after settling, filtration and clarification), Undissolved calcine, sent to washing and waste disposal, Solvent extraction raffinate (~7 g/L Co) from solvent extraction (about 30% of raffinate flow, remainder back to calcine leach), Removal of copper using secondary solvent extraction with LIX 984N, Raise pH to 3.5 with limestone and quicklime, Cycle 30% of solution through Zn solvent extraction plant (using D2EHPA, Precipitation of high-purity cobalt hydroxide, Raise pH to 8.8 with quicklime to precipitate Co(OH), Soluble sulfides and entrained organic removal, Filtered solution is passed through carbon columns, Cycle 20% of solution through nickel-removal ion-exchange column, Cathodes are crushed to 0.02 m × 0.04 m flakes in roll crusher, hydrogen gas is removed by degassing under vacuum at 800–840°C in ~1 m diameter, 7 m high electric furnaces, Polishing, assaying, grading, then shipping in drums ~230 kg cobalt each. 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". In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as … Zdzisław, in Reference Module in Materials Science and Materials Engineering, 2017. ... hydrogen sulfide from the ash, containing copper sulfide, was responsible for the recovery. /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. CuS, for example, can be written as Cu3(S2)S. Several nonstoichiometric compounds with Cu:S ratios between 1.0 and 1.4 also contain both monosulfide as well as disulfide ions. The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. [11][12]. 4 FIRST AID MEASURES. [13] This apparent discrepancy with the X-ray photo-electron spectrum data simply highlights the problem that NMR has in assigning oxidation states in a mixed-valence compound. Elemental copper found in nature can be leached by either oxygen or ferric ion: All copper sulfides require the presence of Fe3+ and O2 as oxidizing agents for leaching to occur. At very high pressures, a copper disulfide, CuS2, can be synthesized. 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. Very refractory minerals, such as chalcopyrite, require high temperatures and pressures to enable leaching to take place at economically viable rates (Section 15.7). In this example, the production of a copper concentrate is investigated. Therefore, this group of copper sulfides shows ionic conductivity at slightly elevated temperatures. 7. This bond length difference has been ascribed to the higher bond order in (S-S)− compared to (S-S)2− due to electrons being removed from a π* antibonding orbital. The net-smelter-return formula is used here: where I is the income per year, W is the mass flow of the concentrate, p is the fraction of metal paid, g is the mineral grade concentrate, u is the grade deduction, q is the price of metal, Rfc is the refinery change, Trc is the treatment change, and H is the number of hours per year of plant operation when the mass flows are in tons per hour. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Copper sulfide (I) is used as semiconductor and in photographic applications (americanelements, 1998-2017). TABLE 30.6. Some copper sulfides are economically important ores. Ingredient: Copper (II) Sulfide. Other leaching methods include ammonia leaching, which is used for certain copper oxide ores. Expert control systems help to optimize the performance of flotation plants. The residuum is removed from the cell and re-melted/cast into fresh anodes and these are placed in the cell. Antiseptic agent 2. Modern concentrators are automatically controlled to give maximum Cu recovery, maximum % Cu in the concentrate, and maximum ore throughput rate at minimum cost. Copper /is/ essential for erythropoiesis in rats fed a milk-based diet. 7. −5 °C – pH=6.1÷11.0 (∆pH=4.9); Eh=−0.59÷−0.29 (∆Eh=0.30). 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. IDENTIFICATION. Their crystal structures usually consist of alternating hexagonal layers of monosulfide and disulfide anions with Cu cations in trigonal and tetrahedral interstices. 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. The copper sulfate test is a visual method of determining the existence of free iron in specifically stainless steel. Estimated flotation stage recoveries, feed mass flow rates and global recovery goals. Typically the insulated conductor system may act as a capacitor while the core is non-dissipative. By continuing you agree to the use of cookies. Precipitation with MgO and redissolution produces cobalt-rich, high-purity electrolyte. With increasing temperature the amount of the copper complexes in the system varies. The anodes are dissolved to the point at which they start to fall apart. Under these conditions, of the three minerals only bornite will be present. But it is more often used to clear sewer lines of invasive tree roots, which can burst pipes and lead to costly repairs if left untreated. It often highlights the green tints of the specific dyes. Copper sulfate helps in eradicating snails that harbor the parasite responsible for … FIGURE 30.7. TABLE 30.5. 6. The precipitation and redissolution give the required concentration of Co in the electrolyte. Prominent copper sulfide minerals include Cu2S and CuS. Therefore, it appears that the application of E–pH diagrams to chloride systems is more complicated than in the case of the sulphate systems owing to the fact that the chloride form a large number of species, electropositive, electronegative and electroneutral. There is a resemblance to the cell of Figure 7. A glance at Table 1, shows that there is little tendency for the iron in the electrolyte to co-deposit with the copper; copper deposition is thermodynamically much more favorable. Both minerals and synthetic materials comprise these compounds. DATE OF LAST REVISION: 07/09/15. SAFETY DATA SHEET . Copper Sulfide is a crystalline solid used as a semiconductor and in photo optic applications. Adjacent cells are connected in series and several hundred cells would be contained in a typical electrorefining tankhouse. [8][9][10] The use of copper dates back more than 10,000 years. Copper sulfate is an inorganic compound that combines sulfur with copper that has been registered for use in the United States since 1956. Copper sulphate is a very versatile chemical with as extensive a range of uses in industry as it has in agriculture. J.W. Fig. TABLE 30.2. Table 5.8.
