  • 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

  • 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

  • copper extraction and purification chemguide

    Extracting copper from other ores. Copper can be extracted from non-sulphide 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.

  • Copper Extraction from Sulfide Ores Latest Contents

    This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.

  • Extraction of Copper from Copper pyrite Grade 12 Science

    The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

  • Copper mining and the copper extraction process explained

    Copper is also extracted from oxidised ores including copper silicates, carbonates and sulphates. Here, the copper ores are crushed and ground as above, but they are then leached with sulphuric acid to produce an impure copper sulphate solution. The solution is purified using solvent extraction
