  • Mining and Extraction: Oxide Ores processes for

    Copper is refined from ores in the ground, either through underground or openpit mines Most of the copper ores mined today are oxide or sulfide ores Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extractionCopper Mining and Extraction: Oxide Ores Copper Leaching Oxide Ores with Sulfuric Acid The flowchart above shows how the smelting process of sulfide ores produces sulphur dioxide, which is converted to sulfuric acid The chart below shows how acid is used to leach out copperflowchart for production of copper by leaching
