Copper Refining an overview ScienceDirect Topics

网页Copper is a relatively uncommon metal that is mostly produced as a by-product of copper and nickel refining. Copper poisoning can result in a variety of health problems, including cramping, convulsions, and even death [189]. Copper ion (Cu 2 + /Cu) has a strong redox potential and, upon reduction, is deposited on cathodes, as seen in.
