Different places and purity prices will be different, about 14- 18 yuan/kg. At present, the recycling price of scrap copper is determined according to the copper price of Yangtze River futures. Scrap copper is divided into copper and brass, and the prices are different.
At present, there is no standard for scrap copper in China, but with the acceleration of industrialization in China, the social and economic environment faced by the recycling, trading and recycling industries of scrap nonferrous metals has changed greatly. Not only has the variety composition of waste non-ferrous metals changed greatly, but also foreign waste non-ferrous metals and various available wastes have flooded into China.
It provides a rich source of raw materials for the production of nonferrous metals in China, and also puts forward new requirements for the production and processing of recycled nonferrous metals.

Matters needing attention
1. chemical method: the technology of treating waste cables by chemical method was put forward in the 1990s, and it was also discussed in China and during the Eighth Five-Year Plan period. This method has a big defect that the waste liquid can not be treated and has a great impact on the environment, so it is rarely used;
2. Freezing method: This method was also put forward in the 1990s. It uses liquid nitrogen as refrigerant to make the waste cable brittle at extremely low temperature, and then the plastic skin is separated from the copper wire section by squeezing and feeling. China also initiated project discussion before the Eighth Five-Year Plan period, but the disadvantage of this method is that it is difficult to carry out industrial production because of high funds.
