    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 silicate, carbonate or sulphate ores Getting copper from chalcopyrite, CuFeS 2 Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper The oresThe 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 isExtraction Of Copper | Mining, Concentration, SmeltingCopper 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
