Copper Production: How Is Copper Made? - ThoughtCo

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.在thoughtco.com上预计阅读时间:7 分钟
