What is cathode copper?
A thick plate of crude copper (99% copper) was prepared in advance as the anode, a thin plate of pure copper was prepared as the cathode, and a mixture of sulfuric acid and copper sulfate was used as the electrolyte. After electricity, 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 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, so as long as the potential difference is properly adjusted during electrolysis can avoid these ions precipitate on the cathode. Impurities less active than copper, such as gold and silver, are deposited at the bottom of the cell. The resulting copper plate, called electrolytic copper, is of very high quality and can be used to make electrical products.
1. Copper is the most widely used and the largest consumption in electrical and electronic industry, accounting for more than half of the total consumption. Used for all kinds of cable and wire, motor and transformer winding, switches and printed circuit boards.
2. In the manufacture of machinery and transport vehicles, they are used to manufacture industrial valves and fittings, instruments, plain bearings, dies, heat exchangers and pumps.
3. In chemical industry, it is widely used in the manufacture of vacuum, still pot, brewing pot and so on.
4. In the national defense industry used to manufacture bullets, shells, gun parts, etc., for every 1 million bullets produced, 13 to 14 tons of copper is used.
5. In the construction industry, used as a variety of pipes, pipe fittings, decorative devices, etc.
