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

    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.

    2.7.4.1.2 Copper Ore Leaching by Ore Type. The leaching of copper ores is conducted somewhat differently depending on the minerals present in the ore. Oxide ores containing chrysocolla, malachite, azurite, cuprite, etc., are readily amenable to acid leaching. An acid solution is often mixed with the ore during agglomeration to initial leaching

  • AZURITE (Hydrated Copper Carbonate)

    Azurite is a very popular mineral because of its unparalleled color, a deep blue called "azure", hence its name. Azure is derived from the Arabic word for blue. The color is due to the presence of copper (a strong coloring agent), and the way the copper chemically combines with the carbonate groups (CO3) and hydroxyls (OH).Azurite has been used as a dye for paints and fabrics for eons.

  • Malachite Wikipedia

    Malachite often results from the weathering of copper ores, and is often found with azurite (Cu 3 (CO 3) 2 (OH) 2), goethite, and calcite. Except for its vibrant green color, the properties of malachite are similar to those of azurite and aggregates of the two minerals occur frequently.
