  • Extraction Of Copper | Mining, Concentration, Smelting

    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 Concentration of Ore: The ore is crushed into a fine powder and aExtracting 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 orescopper extraction and purification chemguide

  • Copper Mining and Processing: Processing Copper Ores

    Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper Although the processing costs areExtracting 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 orescopper extraction and purification chemguide
