Copper Ore Formation

The formation of the native copper ores is not completely understood. The fact that it is a relatively unique deposit of a very large size makes the understanding of the ore formation processes problematic. The lack of sulfur in the ores is a very unusual feature in the formation of copper deposits. Most copper ore deposits will contain some.

    Copper Cu is an extremely useful industrial metal that is ductile capable of being drawn into wire malleable capable of being hammered and molded and an excellent conductor of electricity only silver is better. Copper is found in many minerals that occur in deposits large enough to mine. These include azurite malachite chalcocite.

    Copper. Copper is a reddish relatively abundant easily-worked metal with a bright metallic luster. Its chemical symbol is Cu. Copper occurs as a native metal and as compounds frequently of sulfur that are easily smelted. It is a good conductor of heat and electricity and its main uses are in electrical wire plumbing roofing coins and.

    Copper is among the few metals known to ancient civilizations. Copper gold silver platinum and meteoric iron are the only metals found in their native state. However 90 of copper comes from sulfide ores. Most copper ores contain 0.5 Cu or less iron being the principal metallic impurity. The ores are ground to a fine powder and concentrated normally by floatation to 2025 Cu.

    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.
