A microwave-assisted hydrothermal method sol - gel process copper sulfide film, the glass substrate sequentially immersed in a mixed solution of dilute hydrochloric acid, concentrated sulfuric acid, hydrogen peroxide and deionized water in the activation process, the copper acetate was added to the ...
Soluble in nitric acid, hot concentrated hydrochloric acid, sulfuric acid and sodium cyanide solution, slightly soluble in ammonium sulfide solution, insoluble in water and sodium sulfide solution. It can be oxidized into colloidal state in humid air. The conductivity is better than cuprous sulfide....
The principal ore of copper is chalcopyrite, a sulfide of copper and iron, also called copper pyrite. Other important ores are chalcocite, or copper glance, a shiny lead-gray copper sulfide; bornite, a lustrous reddish-brown sulfide of copper and iron; cuprite, a red cuprous oxide ore; an...

OccurrenceCopper is the 26th most abundant element on Earth, but it is rare to find pure metallicdeposits. It is found in many different types of mineral ores, many of which are close to thesurface and easy to extract. It is found in two types of ores: (1) sulfide ores, such as cov...
A hydrometallurigical process featuring treating sulfide metal concentrate with hydrochloric acid or hydrogen chloride gas and an oxygen-bearing gas (air or oxygen) in an aqueous medium to recover metal from said sulfide metal concentrate is disclosed.DUBECK; MICHAEL...
Black copper(II) sulfide, CuS, is obtained when hydrogen sulfide is passed through dissolved CuCl2. CuCl2 forms several copper(II) complexes with several types of ligands in aqueous solutions. DescriptionCopper chloride is a brownish-yellow powder.Molecular weight =134.44. Boiling point =993℃ (dec...
[83] reported the electroless deposition of a copper sulfide coating on polyacrylonitrile (PAN) with a chelating agent of triethanolamine. However, they obtained a CuS coating, not pure Cu on the PAN film. The aim is to improve the EMI shielding effectiveness. The composition and operating ...
in copper smelting gold, the pattern of using sulfide ore as the main raw material and pyrometallurgy copper as the main material will not change for a long period of time. With the natural enrichment of copper sulfide resources to reduce day by day, suitable for the treatment of poor ore ...
