Electrolytic purification of copper: thick copper (containing 99% copper) is pre-made into a thick plate as an anode, pure copper is made into a thin plate as a cathode, and a mixture of sulfuric acid (H₂SO₄) and copper sulfate (CuSO₄) is used as an electrolyte. After being energized, copper dissolves into copper ions (Cu) from the anode and moves to the cathode. After reaching the cathode, it obtains electrons and precipitates pure copper (also known as electrolytic copper) 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.
