Introduction

Electrolytic Copper is made of blister copper containing 99% copper, pre-made thick plate as anode, pure copper made into thin sheet as cathode, and mixed solution of sulfuric acid and copper sulfate as 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 plate produced in this way, called “electrolytic copper”, is of high quality and is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields.
