Copper (cu) |
Copper ores have been mined for at least 5, 000 years because it is easy to get the copper out of them. For example, if a copper oxide ore (CuO) is heated in a wood fire, the carbon in the charcoal can reduce the oxide to metal: Making pure copper. Extremely pure copper (greater than %), called electrolytic copper, can be made by electrolysis.
