The thick plate made of crude copper (including 99%) is used as anode, the thin plate made of pure copper is used as cathode, and the mixture of sulfuric acid and copper sulfate is used as electrolyte. After being electrified, copper dissolves into copper ions (Cu) from the anode and moves to the cathode, where electrons are obtained and pure copper is precipitated. Impurities such as iron and zinc, which are more active than copper, will dissolve into ions (Zn and Fe) with copper. Because these ions are not easy to precipitate compared with copper ions, they can be avoided to precipitate on the cathode as long as the potential difference is adjusted properly. Impurities such as gold and silver, which are less active than copper, are deposited at the bottom of the cell The copper plate produced in this way, called "Copper Cathode" or "Electrolytic Copper Cathode", is of high quality and can be used to make electrical products.
Application of Copper Cathodes
Copper cathode is an non-ferrous metal which is closely related to human beings.Its widely used in electric, light industry, machinery manufacturing, construction, national defense industry and other fields.
Copper cathode is widely used in electronic industry, accounting for more than half of the total consumption. It is used for winding various cables, wires, motors, transformers, switches, printed circuit boards and other machinery and field.
