  • Copper Production: How Is Copper Made? - The Balance

    Jan 14, 2019· Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) 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.
