:Copper RecoveryCopper Oxide · Azurite: Azurite (Cu3 (CO3)2 (OH)2) is a blue-colored carbonate mineral that is often found in oxidized copper ore deposits. It forms as a secondary mineral through the weathering and alteration of primary copper minerals. Azurite is known for its striking blue color and is used as a gemstone and in jewelry.
