  • Copper production & environmental impact

    Sulfide Ore. The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations. At the end of this smelting process the copper is about 99% pure.. Oxide Ore. The copper-bearing solution is collected and pumped to the extraction plant where it is purified.

  • How is Copper Ore Processed

    The ore contains chalcocite, chalcopyrite, bornite and covellite as sulphides and cuprite, tenorite, malachite, azurite and chrysosolla as oxides, carbonates and silicates and native copper. The sulphides chalcocite, covellite and bornite are products of secondary sulphide enrichment, while chalcopyrite and pyrite are primary minerals.

  • Copper Mining and Production Processes Explained

    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.

  • A review of the beneficiation of copper-cobalt-bearing minerals in the

    Low-grade ore deposits are of increasing interest in mineral processing owing to dwindling resources of high grade, easily exploited ores. For Cu–Co ores in the DRC, oxidised ore deposits have historically been the main source of Cu–Co as they are relatively simple to process, mainly by leaching/solvent extraction/electrowinning.
