  • Extraction Of Copper | Mining, Concentration, Smelting

    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 Concentration of Ore: The ore is crushed into a fine powder and a suspension isExtracting copper from other ores Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution Concentration of the copper(II) sulphate solution by solvent extraction The very dilutecopper extraction and purification chemguideCopper can be extracted 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 This trickles slowly through the ore dissolving copper to formCopper Mining and Extraction Sulfide Ores
