extraction of copper from sulphide

How is copper extracted from its sulphide ore? Explain the various

Answer:In the extraction of copper from its Sulphide Ore when ore is subjected to roasting some of it is oxidised to Cu2O which reacts with the remaining Cu2S to give copper metal.

Copper Mining and Extraction Sulfide Ores

Edu ion Resources Copper Mining and Extraction: Sulfide Ores It’s hard to imagine a world without copper. We rely on copper for power lighting heating communi ions water supply and transport.

copper extraction and purifi ion - chemguide

Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from sili e carbonate or sulphate ores. Getting copper from chalcopyrite CuFeS 2


extraction of copper from sulphide ore Large amount of copper are obtained from copper pyrite CuFeS2 by smelting. Ores containing 4% or more copper are treated by smelting process.

Leaching of Copper Sulphides - SAIMM

The technology should be suitable for retrofits e.g. the conversion of a copper heap leach solvent extraction SX and electrowinning EW facility once the oxide and transition material is exhausted Valkama 2013 . Throughout this paper ‘copper sulphides’ describes both mixed copper–iron sulphides such as

Extraction of copper from sulphides - Free ZIMSEC and Cambridge Revision

Flux is a material used to purge impurities from another metal copper in this case during the smelting process; The sulpher burns off as a gas: \text copper sulphide oxygen \rightarrow\text copper sulpher dioxide Slag which contains most of the unwanted impurities forms a layer at the top of the molten copper and is tapped off

Mining and Extraction: Oxide Ores - processes for extracting copper

Most of the copper ores mined today are oxide or sulfide ores. 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. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Copper Extraction from Sulfide Ores - Latest Contents

This process is used for the extraction of copper from low grade sulfide ore. In this process the crushed and ground ore in bulk about 100000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.
