What is cathode copper electrolytic copper?

Cathode copper is also what we call electrolytic copper, and cathode copper is another name for electrolytic copper. The cathode copper is made of thick copper (containing 99% copper) as the anode, pure copper 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.

Blister copper refined copper electrolysis

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 anode 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.

Copper electrolysis requires special electrolysis equipment or production lines, which can convert a large amount of blister copper into refined copper to improve its utilization rate.
