Electrolytic purification of copper: coarse copper is made into thick plate in advance as the anode, pure copper is made into thin sheets as the cathode, sulfuric acid (H2SO4) and copper sulfate (CuSO4) mixed liquid as the electrolyte. After the current is energized, copper dissolves into copper ions (Cu) from the anode and moves to the cathode, where electrons are acquired and pure copper (also known as electrolytic copper) is precipitated.
Impurities in coarse copper such as iron and zinc, which are more active than copper, dissolve with copper into ions (Zn and Fe). Because these ions are not easy to precipitate compared with 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 at the bottom of the cell. The copper plates thus produced, called “electrolytic copper”, are of very high quality.
KES large – capacity rectifier is a kind of three-phase ac power conversion into voltage adjustable dc power device. Widely used in electroplating, electrolysis, electrochemistry, oxidation, electrophoresis, smelting, electrocasting, communication and other fields, mainly aluminum, magnesium, lead, zinc, copper, manganese, bismuth, nickel and other non-ferrous metal electrolysis; Salt water, potassium salt electrolytic caustic soda, potassium alkali, sodium; Potassium chloride electrolysis to produce potassium chlorate, potassium perchlorate; Steel wire heating, silicon carbide heating, carbon tube furnace, graphitization furnace, melting furnace and other heating; Electrolysis of water to produce hydrogen and other high-current fields.
