Copper Production: How Is Copper Made? - ThoughtCo

Sulfide Copper Ores . 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.

Azurite: The blue gem material, ore of copper, and pigment.

Geologic Occurrence. Azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment.
