Copper From Beginning to End Copper is a major metal and an essential element used by man It is found in ore deposits around the world It is also the oldest metal known to man and was first discovered and used about 10 000 years ago And as alloyed in bronze (copper tin alloy) about 3000 BC was the first engineering material known to man.In an integrated process copper bearing materials are leached with dilute sulfuric acid and the dilute pregnant leach solution is reacted with ferrous scrap to produce cement copper precipitate containing copper metal ferrous impurities and normally refractory metal impurities The raw cement copper is preliminarily treated to separate portions of the ferrous impurities and is then melted.
