Every year, 50% of copper is purified into pure copper by electrolysis and used in the electrical industry.
The red copper mentioned here must be very pure, with copper content of more than 99.95%. A small amount of impurities, especially phosphorus, arsenic and aluminum, will greatly reduce the conductivity of copper.
Oxygen in copper (it is easy to mix a small amount of oxygen during copper smelting) has a great impact on the conductivity.
Copper used in electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony and bismuth will make the crystallization of copper unable to combine, resulting in heat brittleness, and will also affect the processing of pure copper.
This kind of pure copper with high purity is generally refined by electrolysis: impure copper (i.e. crude copper) is used as anode, pure copper is used as cathode, and copper sulfate solution is used as electrolyte.
When the current passes through, the impure copper on the anode gradually dissolves, and the pure copper gradually precipitates on the cathode.
Copper refined in this way; The purity can reach 99.99%. Red copper is a relatively pure copper, which can be approximately considered as pure copper, with good conductivity and plasticity, but poor strength and hardness. The Pure Copper Sheet plates can be cut into various shapes as needed and can be processed into various parts, such as gaskets, washers, crafts, and so on.
