The facts on copper What is Copper? Copper is a light reddish-brown metallic element with the symbol "Cu" and atomic number 29 on the periodic table of the elements. The name copper is derived from the word Cyprus, the island where the Romans obtained their copper supply. It was the first metal to be widely used by humans.
After washing the organic, the copper on the extractant is stripped into a pure copper electrolyte, providing the feed to copper electrowinning. LME Grade A copper cathodes (99.999% Cu) are produced under conventional electrowinning conditions. An evaporator is used to maintain the plant water balance.
