Copper Geoscience Australia
Chalcopyrite in Australia is found in rocks that are more than 250 million years old. Bornite (Cu 5 FeS 4), covellite (CuS) and chalcocite (Cu 2 S) are important sources of copper in the world and many ore bodies also contain some malachite (CuCO 3.Cu(OH) 2), azurite (Cu 3 (CO 3)2.Cu(OH) 2), cuprite (Cu 2 O), tenorite (CuO) and native copper

Cobre mine, Cuba
Depletion of the ore forced deeper and more expensive extraction, and this combined with falling copper prices led to the decision to close the mine in 2001. From the time mining began in 1544 to the end of operations in 1998 over 3 million tonnes of ore were extracted, with grades of 2% to 20% copper.

Copper
CharacteristicsCopper is a chemical element with the symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkishorange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermoco

CopperNickel Welding and joining plate, sheet and pipe
While copper and nickel are mutually soluble with each other as shown in Figure 1, a number of other elements are not soluble in the CuNi alloy and if present may cause cracking in the heat affected zone (HAZ) or weld metal.Lead, sulfur and phosphorus are particularly detrimental and may cause intergranular hot cracking in highly restraint joints.
Copper Mining and Processing Processing of Copper Ores
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
