  • How Extraction of Copper from Copper Pyrites? QS Study

    Extraction of copper from copper pyrites involves the following steps Crushing and concentration The ore is crushed and then concentrated by froth floatation process.

  • Extraction of Copper from Copper pyrite Grade 12

    The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration, Roasting, Smelting and Bassemerisation.

  • Extraction of copper from copper pyrites (CuFeS2

    Extraction of copper from copper pyrites (CuFeS2) Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur.

  • Extraction of copper is done from copper pyrites which

    Extraction of copper is don chemistry. Extraction of copper is done from copper pyrites which contain small quantity of : A. zinc. B. iron. C. sodium. D. carbon. MEDIUM. Answer. The principle ore of copper is copper pyrite, C u F e S

  • Why is the extraction of copper from pyrites more

    13.10.2019· On the other hand, the Gibbs free energy of formation of Cu 2 O is greater than that of CO. Hence, C can reduce Cu 2 O to Cu. C (s) +Cu 2 O (s) → 2Cu (s) + CO (g) Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore through reduction.

  • Mining And Extraction Of Copper From Its Ore Flowchart

    Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

  • Why is the extraction of copper from pyrites more

    Why is the extraction of copper from pyrites more difficult than that from its oxide ore through reduction? MEDIUM. Video Explanation . Answer. In the Ellinggam diagram (graph of Δ r G o vs T) for the formation of oxides, copper-copper oxide line is almost at the top. Hence, oxide ores of copper can be easily reduced to copper by heating with coke. The Δ G o vs T lines for CO

  • The Extraction of Copper Chemistry LibreTexts

    Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain

The gibbs free energy formation f g of cu 2 s is less than that of h 2 s and cs 2erefore, h 2 and c cannot reduce cu 2 s to cuon the other hand, the gibbs free energy formation of cu 2 o is greater than that of co hence, c can reduce cu 2 o to cuc s cu 2 o s 2cu s co g hence, the extraction of copper from its pyrite ore is difficult than from

  • Extraction of copper from copper pyrites (CuFeS2

    Extraction of copper from copper pyrites (CuFeS2) Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2-----> SO 2 4AS + 3O 2----->2AS 2 O 3 2. Copper pyrites is
