  • copper extraction and purification - chemguide

    The process. The concentrated ore is heated strongly with silicon dioxide silica, calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper II ions in the chalcopyrite are reduced to copper I sulphide which is reduced further to copper metal in the final stage

  • Extraction Of Copper | Mining, Concentration, Smelting

    Copper Mining: The commonest ore used in the extraction of copper is 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

  • Copper Extraction from Sulfide Ores - Latest Contents

    EXTRACTION OF COPPER FROM SULPHIDE ORES Copper is mostly extracted from the sulphide ore, copper pyrites, by means of the following two processes: i-Smelting process ii-Hydrometallurgical process SMELTING PROCESS Modern copper metallurgy is based on the smelting process. Following steps are involved: i. CONCENTRATION OF THE ORE

  • Extraction of copper from cuprous oxide - Self Study Point

    of from cuprous oxide [ I oxide] is mainly from CuFeS 2.The involve the following steps given in flow sheet

  • Copper Mining and Extraction Sulfide Ores

    can be from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid

  • The Extraction of Copper - Chemistry LibreTexts

     · The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite C u F e S 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


    Large amount of copper are obtained from copper pyrite CuFeS2 by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS


    metal is from molten matte through bessemerization . The matte is introduced in to Bessemer converter which uphold by tuyers. The air is blown through the molten matte. Blast of air converts Cu2S partly into Cu2O which reacts with remaining Cu2S to give molten

  • copper Cu - David Darling

    Most is from , also known as chalcopyrite. The raw from ores is not pure enough for electrical purposes and is further purified by electrolysis

  • In the extraction of copper from its sulphide ore, the

    The metal is mainly from is sulphide ore CuFeS 2 .The Cup obtained can be reduced to by treating with Cu 2 S. 2Cu 2 S → 3 O 2 2Cu 2 O + 2SO 2 Switch

  • Copper extracted from copper pyrites ore in blast furnace

    The method used to from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to by a different method from silicate, carbonate or sulphate ores. Chalcopyrite also known as and similar sulphide ores are the commonest ores of


     · Most is from , CuFeS 2. The ore is roasted in a limited supply of air to produce to produce I sulphide: 2CuFeS 2s + 4O 2g → Cu 2 S s + 3SO 2g + 2FeO s The I sulphide is then reduced to by heating in
