  • Copper Mining and Extraction: Oxide Ores

    Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching. The process used to treat sulfide copper ores begins at the mine site, where the copper

  • ANDRITZ thickening solutions for beneficiating oxidized

    Start beneficiating oxide ore alongside sulfide ore. In the mining industry, beneficiation increases the value of the ore by removing the gangue minerals, i.e. the worthless material mixed in with the desired substance. In 2018, Comika was already beneficiating sulfide ore and moving into oxide ore. Unlike sulfide ore, the beneficiation of oxide ore involves acid leaching, where the copper is

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

    1/11/2019· Ziyadanogullari and Aydin (2005) investigated the thermal sulphidisation of a Cu oxide ore from the Ergani Copper Mining Co, in southeast Turkey. The ore sample used contained 2.03% Cu, 0.15% Co, and 3.73% S. The valuable minerals present were chrysocolla, chalcopyrite, and native copper. The gangue comprised pyrite, carbonate, calcite, and clay minerals. The ore (of a size up to

  • Iron oxide copper gold ore deposits Wikipedia

    Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging
