The blister copper (99% copper content) is pre-made into a thick plate as the anode, pure copper is made into a thin sheet as the cathode, and a mixed solution of sulfuric acid and copper sulfate is used as the electrolyte. After energization, copper dissolves into copper ions (Cu) from the anode 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 into ions (Zn and Fe) along with copper. Since these ions are less likely to be precipitated than copper ions, the precipitation of these ions on the cathode can be avoided by appropriately adjusting the potential difference during electrolysis. Impurities that are less active than copper, such as gold and silver, are deposited at the bottom of the electrolytic cell. The copper plate produced in this way, called "electrolytic copper", is of extremely high quality and can be used to make electrical products.

Electrolytic copper is a non-ferrous metal closely related to humans. It is widely used in electrical, light industry, machinery manufacturing, construction industry, defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in my country. Copper is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used in various cables and wires, windings of motors and transformers, switches and printed circuit boards, etc.

In the manufacture of machinery and transportation vehicles, it is used to manufacture industrial valves and fittings, meters, sliding bearings, molds, heat exchangers and pumps.

It is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.
