Scrap copper refers to copper products or copper scrap that are no longer used. As people's awareness of environmental protection increases, the treatment of scrap copper has also received more attention. The following are several common waste copper treatment methods: 

1、Smelting, recycling and smelting is one of the most common waste copper treatment methods. By heating the scrap copper to high temperatures, metal copper in the copper product can be melted. The melted copper can be poured into the mold and re-formed, and used to make copper products again. This treatment method not only recycles copper resources, but also reduces the pollution of waste copper to the environment. 

2、Electrolysis recycling is another common method of scrap copper treatment. By adding scrap copper products to the electrolytic cell, copper ions are precipitated in the electrolyte through the action of electric current, and finally pure copper is formed. This method can efficiently recover copper resources and have less environmental pollution.

3、Processing and reusing scrap copper can also be processed through processing and reuse. The scrap copper products can be processed, such as shearing, compression, etc., and can be converted into copper blocks, copper wires, etc., and then reused to manufacture copper products. This method not only allows copper resources to be recycled, but also reduces energy consumption during scrap copper treatment. 

4、Environmentally friendly treatment. For waste copper products containing harmful substances, such as lead-containing copper products, environmentally friendly treatment is required. This treatment mainly includes physical and chemical treatment. Physical treatment separates harmful substances from copper through separation, filtration and other methods. Chemical treatment is to convert harmful substances into harmless substances through chemical reactions. This method can protect the environment and reduce the harm of harmful substances to the ecosystem.

To sum up, there are many ways to treat waste copper, including smelting and recycling, electrolytic recycling, processing and reuse, and environmental protection treatment. These treatment methods can not only recycle copper resources, but also reduce environmental pollution and protect the ecological environment. In the future, with the advancement of science and technology and the enhancement of environmental awareness, the scrap copper treatment method will be more perfect and efficient.
