  • Copper Mining and Extraction Sulfide Ores

    Copper 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.

  • How is copper extracted from its Sulphide ore ? Explain

    In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S to give copper metal. In this process, Cu 2 S behaves as reducing agent.. 2Cu 2 S+3O 2 +heat→2Cu 2 O(s)+2SO 2 (g). 2Cu 2 O+Cu 2 S+heat→ 6Cu(s)+SO 2 (g). In electrolytic refining of copper, the impurities left behind at

  • 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.

    Sulphide ores are extracted by the process of roasting: They are heated in the presence of air. 2CuS +3O₂ -----> 2CuO +2 SO₂. Then the ore is reduced to it's elemental form: 2CuO ----Δ----> 2Cu + O₂. Copper can also be extracted by the process of electrolytic refining. This is the apparatus: Anode: Impure metal.

    Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
