What does electrolytic copper distinguish with red copper have?

Red copper is pure copper, also known as The British copper industry copper has good electrical conductivity and thermal conductivity, excellent plasticity, easy to hot pressing and cold pressure processing, can be made into tubes, rods, lines, strips, strips, plates, foil and other copper materials. As a result of high purity, red copper organizes fine, contain oxygen extremely low, without stomatal, trachoma, crack, impurity, conductive performance is beautiful. The surface finish of electroetching mould is high. After heat treatment, the electrode has no direction. It is suitable for fine and fine beating. Now it is widely used in manufacturing wire, cable, electric brush, electric spark special etching copper and other products requiring good electrical conductivity, magnetic instruments and instruments, such as compasses, aviation instruments and so on. Copper sulfate in agriculture and forestry can control pests and diseases, inhibit the algae in water mass reproduction.

Electrolytic purification of electrolytic copper: coarse copper (containing 99% copper) is made into thick plate as anode, pure copper is made into thin sheet as cathode, sulfuric acid (H2SO4) and copper sulfate (CuSO4) mixed liquid as electrolyte. After the current is energized, copper dissolves into copper ions (Cu) from the anode and moves to the cathode, where electrons are obtained 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 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 at the bottom of the cell. The copper plate produced in this way is called "electrolytic copper", which is of high quality and can be used to make electrical products. The deposit at the bottom of the electrolytic cell is called "anode mud", which is rich in gold and silver, which is very valuable and has high economic value for reprocessing.
