  • The Extraction of Copper Chemistry LibreTexts

    Aug 21, 2020· Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) 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

  • 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.

    Extraction of MetalsConvert Ores to OxidesReduction of Metal OxidesSolved Question For YouNow we already saw how the ore of a metal is concentrated to remove impurities known as gangue. After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form i.e. the native form of metal. First, we must convert the ore to a suitable form. The metals need to be in an oxide form for the reduction process to be easier. Hence the ores are converted to oxides, so it is ideal for reduction. After doing so the ores will undergo reduction, to give us metal. Therefore the two main step
