Electrolytic copper cathode production line

The blister copper (containing 99% copper) is pre-made into a thick plate as the anode, the pure copper is made into a thin sheet as the cathode, and the mixed solution of sulfuric acid (H2SO4) and copper sulfate (CuSO4) is used as the electrolyte. After electrification, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. After reaching the cathode, electrons are obtained and pure copper (also known as electrolytic copper) is precipitated at the cathode. Impurities in blister copper, such as iron and zinc, which are more active than copper, will dissolve together with copper as ions (Zn and Fe). Since these ions are less likely to be precipitated than copper ions, the precipitation of these ions on the cathode can be avoided as long as the potential difference is properly adjusted during electrolysis. Impurities less reactive than copper, such as gold and silver, are deposited on the bottom of the cell. The copper plates produced in this way, called "electrolytic copper", are of extremely high quality and can be used to make electrical products.

Electrolytic copper is a widely used metal. It has unique advantages in electrical conductivity, potential conductivity, tensile strength, extensibility, corrosion resistance, fatigue resistance, etc. Electrolytic copper is very closely related to human beings. The non-ferrous metals are widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields.
