  • Copper Mining and Processing: Processing Copper Ores

    A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling CopperSulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill using secondary crushe

    Sulfide Copper OresOxide Copper OresIn-Situ LeachingProducing Copper from Recycled SourcesVirtually all sulfide-type copper ores, including chalcocite (Cu2S), chalcopyrite (CuFeS2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic. The mixture is then bathed in water along with a foaming agent, which encourages frothing.See more on thoughtcoEstimated Reading Time: 6 mins
