  • 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 aExtracting iron and copper Ores Unreactive metals such as gold are found in the Earth's crust as the uncombined elements However, most metals are found combined with other elements toExtracting iron and copper Reactions of metals AQAExtracting 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 Thecopper extraction and purification chemguide
