There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. The quantity of lime used can be reduced considerably. Preparation of sulfides If not breathing, administer artificial respiration (Copper (II) Sulfide, 2009). These compounds can be differentiated by their crystalline structure. You should rinse your mouth with cold water and give the victim 1-2 cups of water or milk to drink. (2014). Chemical and physical properties vary depending on the components present. [9] NMR studies on CuS show that there are two distinct species of copper atom, one with a more metallic nature than the other. That is because they have high copper content, and the copper in … If swallowed, call a poison control center immediately. The issue of the valence of copper in sulfides (as well as selenides and tellurides) continues to be revisited in the literature. Some copper sulfides are economically important ores. Cleavage is perfect in one direction forming thin sheets. The naturally occurring mineral binary compounds of copper and sulfur are listed below. It is a moderate conductor of electricity. Whatever their source, copper sulphides vary widely in composition with 0.5 ≤ Cu / S ≤ 2, including numerous non-stoichiometric compounds. Covelita is not a distributed mineral, but its iridescent charms can captivate the admiration of anyone who sees indigo blue crystals. The Copper sulphides Describe a family of chemical and mineral compounds with the formula Cu X S Y . Depending on their composition, these copper sulfides are either semiconductors or metallic conductors. Contains copper and lead sulfide in copper concentrates. 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. Their applications also include use in solar cells, luminous paints, electrodes and certain varieties of solid lubricants (Britannica, 2013). (S.F.). Britannica, T. E. (2013, Aug. 23). Properties, SDS, Applications, Price. Retrieved from pubchem.ncbi.nlm.nih.gov. Symptoms include vomiting, gastric pain and dizziness, may cause irritation to the skin and eyes and inhalation may cause respiratory irritation (MATERIAL SAFETY DATA SHEET Copper Sulfide, 1995). Alginate-based functional nanocomposite films were prepared by the incorporation of copper sulfide nanoparticles (CuSNP) using a solution casting method and characterized their properties. 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). Retrieved from onboces.org. This method, developed by Lionel Milberger, is a low-cost, accessible way to detect if hydrogen sulfide is present in the air. These compounds can be differentiated by their crystalline structure. Properties of Copper Sulfide. THE MINERAL CHALCOCITE. Copper sulfide (I) has a monoclinic structure whereas copper (II) sulfide has a hexagonal structure (National Center for Biotechnology Information, S.F.). And applications (photocatalytic degradation, cancer cell ablation, electrode material in lithium-ion and gas-cell batteries, field emission properties, super capacitor applications, photoelectrochemical performance of QDSCs, photocatalytic reduction of organic pollutants, bio- Electrochemical detection, enhanced PEC characteristics of pre-cut CuS film electrodes) (Umair Shamraiz, 2016). Copper (Cu). The covalent property of sulfur allows sulfur-sulfur bonds and the incorporation of S 2 pairs in some sulfides such as pyrite. Copper (II) sulfide has a melting point of 220 ° C where it decomposes, is insoluble in water, hydrochloric and sulfuric acid and is soluble in nitric acid, ammonium hydroxide and potassium cyanide (Royal Society of Chemistry, 2015 ). In case of contact with eyes, they should be rinsed immediately with sufficient amount of water for 15 minutes, raising the lower and upper eyelids occasionally. Retrieved from chemspider.com. Copper Sulfide Nanoparticles As a New Class of Photoacoustic Contrast Agent for Deep Tissue Imaging at 1064 nm. Retrieved from onboces.org. (2014). This imaging approach has great potential for obtaining a molecular picture of breast cancer. Retrieved from americanelements.com. Its crystal structure is analogous to that of pyrite, with all sulfur atoms occurring as S-S units. Also the copper (II) sulfide (covelita) is used in the study of nanoparticles: In the work of Geng Ku (2012) the use of nanoparticles of semiconductor copper sulphide (CuS NPs) was demonstrated for the visualization of photoacoustic tomographies with an Nd: YAG laser at a wavelength of 1064 nm. However, it is not the main mineral of copper due to its scarcity. Pyrite is a major source of iron and is one of the most abundant of the sulfur minerals. LABEL IDENTITY Copper Sulfide CHEMICAL NAME/SYNONYMS Copper Sulfide FORMULA Cu2S (or Cu1.8S) CHEMICAL FAMILY Metal Sulfide CAS REGISTRY NUMBER 22205-45-4, LISTED IN THE TSCA INVENTORY HAZARDOUS INGREDIENTS Copper Sulfide %: 100 TLV: 1mg/m3 OSHA/PEL: 1mg/m3 (as Cu) (as Cu) PHYSICAL AND CHEMICAL PROPERTIES • pH and NaHS concentration affect Fe 2 O 3 reprecipitation onto bornite and chalcopyrite. Fracture is flaky. Immediately induce vomiting. [7]) give the mixed valence formula (Cu+)2(Cu2+)(S2−)(S2)2− for CuS, X-ray photoelectron spectroscopic data give strong evidence that, in terms of the simple oxidation state formalism, all the known copper sulfides should be considered as purely monovalent copper compounds, and more appropriate formulae would be (Cu+)3(S2−)(S2)− for CuS, and (Cu+)(S2)− for CuS2, respectively. Copper monosulfide is a chemical compound of copper and sulfur. Both Cu2S and the copper-deficient Cu1.97S have very similar but distinguishable electronic and crystal structure. 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 polarizers Infrared (azom, 2013). All presented Cu2−xS NCs show a blue shift in the band gap absorption compared to bulk Cu2−xS. Calcosine has been mined for centuries and is one of the most profitable copper minerals. Eng.,19', 204 (2006). In virtually all of the sulfides, bonding is covalent, but some have metallic properties. Therefore, this group of copper sulfides shows ionic conductivity at slightly elevated temperatures. Whatever their source, copper sulfides vary widely in composition with 0.5 ≤ Cu/S ≤ 2, including numerous non-stoichiometric compounds. Retrieved from galleries.com. Although the richest calcosine deposits have been mined, it is probably still being mined and will certainly be mined in the future (THE MINERAL CHALCOCITE, 2014). Copper sulfide has received wide attention as a potential thermoelectric material with high performance and abundant resource. Immediate steps should be taken to limit spread to the environment. Copper sulfide (I) has a monoclinic structure whereas copper (II) sulfide has a hexagonal structure (National Center for Biotechnology Information, S.F.). Also massive and in small grains in sulfide ore bodies. It can be classified into three groups, namely monosulfide, disulfide and mixed monosulfide. [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. (2015). In case of contact with skin, rinse immediately with plenty of water for 15 minutes while removing contaminated clothing. Sulfide ores contain sulfur. It has been mined for centuries and is one of the most profitable copper ores. Although many textbooks (e.g. At very high pressures, a copper disulfide, CuS2, can be synthesized. Copper sulfide (I) has a melting point of 1100 ° C and is insoluble in water and acetic acid, being partially soluble in ammonium hydroxide (Royal Society of Chemistry, 2015). MATERIAL SAFETY DATA SHEET Copper Sulfide. 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. The elemental copper will react with hydrogen sulfide to produce a purple-black-ish copper sulfide product, visible on the surface of the copper rod. *Please select more than one item to compare [6], The bonding in copper sulfides cannot be correctly described in terms of a simple oxidation state formalism because the Cu-S bonds are somewhat covalent rather than ionic in character, and have a high degree of delocalization resulting in complicated electronic band structures.
