· Copper is so valuable that its theft from worksites and power substations has become a national problem. Replacing the lost copper with new metal produced by the traditional method of cooking copper sulfide ores requires a multistep process to extract the copper and produces troublesome byproducts.
Learn MoreThe copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wetted, suspended in a slurry, and mixed with xanthates or other reagents, which render the sulfide particles hydrophobic.

Learn More· Copper ii sulfide or cupric sulfide represented by the chemical formula CuS that bears the IUPAC name sulfanylidenecopper is a black powder or lumps that is soluble in nitric acid but insoluble in water. It occurs as the mineral covellite and is an ionic compound [3, 4].
Learn More· And then, the anchoring effect occurred due to the hydrogen bonding between the pits of PAN substrate and the chelating agent. Consequently, the copper sulfide layer deposited by the electroless plating reaction with EDTA and TEA. The swelling degree (S d) was proposed and evaluated from the FT‐IR spectra.
Learn MoreReaction of copper with sulfide. Copper(II) is precipitated by sulfide in M hydrochloric acid Cu 2+ (aq) + H 2 S (aq) CuS (s) + 2 H + (aq) Reaction of copper with water. Copper(II) forms a hexaqua complex with water. The complex is slightly acidic, due to hydrolysis [8]
Learn MoreMagmatic sulfide deposits containing nickel (Ni) and copper (Cu), with or without (±) platinum-group elements (PGE), account for approximately 60 percent of the world's nickel production. Most of the remainder of the Ni production is derived from lateritic deposits, which form by weathering of ultramafic rocks in humid tropical conditions.

Learn MoreControlled adsorption at the surface of copper sulfide minerals 135 So, no adsorption of those substances at the non-stoichiometric copper (I) sulfide surface has occurred. The nonionic surfactant (n-octanol) caused limited decrease in the capacitance of the EDL and the course of the dependence of
Learn MoreCopper is recommended as a supplementary method of increasing biological safety in the hospital environment. The objective of this study was to determine the antibacterial activity of copper sulfate salts on strains of bacterial pathogens isolated from different clinical pictures in different health establishment in Algeria.
Learn More· Some copper sulfide ores also contain significant quantities of gold and silver. According to the mineral compositions, these ores can be sub-divided into three main groups including (a) copper-gold ore, (b) copper sulfide ore with moderate pyrite content and (c) massive sulfide copper ores.

Learn MoreCopper(I) sulfide is an ionic compound which means we need to cross multiply the charges (oxidation numbers) to get the correct formula. Cu has a charge of +1 as indicated by the roman numeral in the name and S has a charge of -2 since its in group 16 of the Periodic table.
Learn MoreThe purpose of this study was: (1) to find the effect of temperature on the wet oxidation of chalcopyrite, pyrite, and copper sulfide over the biological and nonbiological range; (2) to determine the influence of ferrous and ferric iron and free oxygen(air) on the oxidation. The sulfide minerals studied were oxidized over a range of temperatures between 25° to 75° C.
Learn More· containing copper sulfide) and a copper tolerant cladosporium fungus was detectable Brinch MadsenThey occurred together with silver sulfide whiskers, rubber mats were seen as the source of volatile sulfur. Rarely, the necessary reduced sulfur sources emitting e. g. hydrogen or carbonyl sulfide for the occurrence of Zlack Spots [
Learn MoreTwo-dimensional (2D) semiconductors with suitable direct band gaps, high carrier mobility, and excellent open-air stability are especially desirable for material applications. Herein, we show theoretical evidence of a new phase of a copper(i) sulfide (Cu2S) monolayer, denoted δ-Cu2S, with both novel electron
Learn MoreCopper sulfide belongs to a family of chemical compounds and minerals with the formula CuxSy. It can be classified into three groups, namely monosulfide, disulfide and mixed monosulfide. Copper sulfide occurs naturally in nature as a mineral called covellite.
Learn MoreHydrogen sulphide (H 2 S) is considered one of the most corrosive atmospheric pollutants. It is a weak, diprotic, reducing acid, readily soluble in water and dispersed into the air by winds when emitted from natural, industrial, and anthropogenic sources. It is a pollutant with a high level of toxicity impairing human health and the environment quality.
Learn MoreCopper sulfide dendrites and subsequent uniform nanowires up to tens of micrometers long can be grown on carbon-coated transmission electron microscopy (TEM) Cu grids from elemental sulfur at room temperature under ambient conditions without
Learn MoreCopper is also a key base metal for green and renewable products, and is used extensively in the production of electric vehicles, solar panels and wind turbines. Production. Pure copper is usually produced from a multistage process, starting with the mining and concentrating of low-grade ores that contain copper sulfide minerals.
Learn MoreCopper sulfide is a p-type semiconducting material which belongs to I-VI compound semiconductor metals. Chalcogenide thin films of copper sulfide have received particular attention since the discovery of the CdS/CuS hetrojunction solar cell in 1954 [1]. Other applications of CuS thin films include laminated glazing,
Learn MoreCopper sulfide has attracted much attention over the years for its various unique properties, 26 for which it has been applied in numerous fields such as optical filters, room temperature ammonia gas sensing, lithium rechargeable batteries, and photocatalysis. 2730 Herein, we have demonstrated a solution phase synthetic protocol for porous copper sulfide by mixing an
Learn MorePotential for New Nickel-Copper Sulfide Deposits in the Lake Superior Region. Scientists from the Geological Survey are evaluating the potential for undiscovered sulfide deposits containing varying amounts of nickel, copper, platinum-group metals, and cobalt in the Lake Superior region as part of an ongoing effort to assess the mineral
Learn MoreIn the copper sulfide system, sulphur has a higher diffusion coefficient than copper, which results the formation of nonstoichiometric Cu 2− x S structure. 28,29 In the XRD pattern, the most intense peak can be indexed as the interlayer spacing of the stacked aromatic segments in the (002) planes with a distance of nm of the conjugated aromatic ring with lattice constant
Learn More· The discovery that copper could also be obtained by heating Blue Stones or minerals (primarily copper sulfide ores) occurred between 4000 – 3000 BC. The extraction of Copper from Copper Sulfide Ores provided Man with another, more abundant source of copper.
Learn More· However, little deposition of copper sulfide occurred even after 432 h of heating when either of these passivators was added to the oil. The concentration of dissolved copper significantly decreased when either of these passivators was added to the oil, which reflects the formation of complex layers on the copper surface caused by the reaction between these
