Azurite The blue gem material ore of copper and pigmentUses of Copper Supply Demand Production Resources

Azurite is a secondary mineral that usually forms when carbon dioxide laden waters descend into the Earth and react with subsurface copper or 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 environmentWhat Properties Make Copper Useful The excellent alloying properties of copper have made it invaluable when combined with other metals such as zinc to form brass tin to form bronze or nickelThese alloys have desirable characteristics and depending on their composition are developed for highly specialized applications
