  • extracted of copper from ores - griffonner

    The Extraction of Copper - Chemistry LibreTexts. Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper(II) sulfate solution.

    Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3 Cu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3 Cu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2

    Leaching is the process to extract pure copper from a low grade ore. Leaching is the process of extracting substances from a solid by dissolving them in a liquid, in this process the ore is dissolved in liquid but not impurities. Then the copper solution is reacted with iron to get pure copper (reduction process). C u 2 + + H 2 → C u (p u r e ...

    Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

  • Extracting copper. Extracting copper.

    Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.
