Chemical composition & Mechanical characteristic
Copper is obtained from copper ore and copper scraps. There are three kinds of copper ore; sulfide ore, oxide ore and natural copper. Natural and oxide ores are the secondary products of sulfide ore, which is 65% of the whole amount of copper ore. Most of the sulfide copper ore is processed into copper by pyrometallurgical process. As the sulfide copper ore isn't reduced as it is, the ore is first processed into 30-50% Matte in blast, reverberatory or flash furnace and then copper anode with 98% purity in converter. Finally, electrolytic copper with higher than 99.99% purity from the copper anode through electrolytic refining process.
