How many recycling methods of separating copper from scrap cable wires?

Some recyclers understand that metallic copper and non-metallic plastics can be recovered from waste cable wires, so they have the idea of recycling waste cable wires. However, since the early stage of cable recycling business is not very well understood, They often ask the recycling methods of separating copper from scrap cable wires. Here, we DOING company to introduce to you.

Recycling waste wires and cables, we want to obtain the metal copper and plastic inside, so the ultimate purpose is to separating copper from scrap cable wires. Recycling methods of separating copper from scrap cable wires has fire burning, manual peeling method, chemical method, freezing method, water washing, mechanical crushing and other processing methods. In the following, we summarize the recycling processing methods of waste wires and cables as follows.

Recycling methods of separating copper from scrap cable wires

Fire burning: This method uses the combustible nature of the wire sheath to directly burn scrap cable wires, and then recover the copper inside. The copper was burned by fire. During the process of burning, the copper was severely oxidized, which reduced the copper recovery rate. But the plastic on the surface of the cable was burned, causing waste of resources.

Washing method: In addition to burning copper, there are also washing method. Corrosion and oxidation of copper separated by water-type copper wire recycling equipment damaged the performance of copper. And how to deal with the large amount of waste water generated in the production process is also a difficult problem.

Manual peeling: The manual peeling method is to manually peel the copper and plastic from scrap cable wires. However, this method has low efficiency and high cost, and has a poor processing effect on automobile wires, network wires, and household appliance disassembly wires. With the current economic development, labor costs are getting higher and higher, and fewer and fewer waste wires and cables are treated by this method.

Chemical method: This method uses chemical potion, which is separated from copper by immersion treatment of potion. The problem is that the medicinal solution produced is not easy to handle and will cause large environmental pollution. Therefore, this method is only in the experimental stage and has not been put into civilian use.

Freezing method: Liquid nitrogen is used as a refrigerant, so that scrap cable wires are frozen at ultra-low temperature and become brittle, and then are broken and shaken to separate plastic and copper. This method has high cost, is difficult to operate on a large scale, and has not been put into actual production.

Mechanical crushing method: This method uses dry copper wire granulator machine to completely separate and recycle copper and plastic through crushing, crushing, air separation, and electrostatic separation. The whole process is dry physical sorting, without using water, fire and any chemical raw materials, so there is no secondary pollution. There is no requirement for raw materials for copper wire granulator machine, and any domestic or industrial wire can be processed. The purity of copper and plastic processed by copper wire granulator machine can reach over 99%.[Related reading: How do I separate copper from scrap cable wires?]
