Scrap copper, as a very important material in the copper industry, has a very serious effect in the production process of the copper industry.

There are two types of scrap copper according to its origin. One type is old scrap copper, which is the item thrown away after use. It is the item thrown away after use, such as discarded or dismantled from old buildings and transportation systems, called old scrap copper.

Another type is new scrap copper, which is the waste generated during the copper industry production process. Generally speaking, new scrap copper accounts for more than half of the scrap copper used for regeneration.

After reprocessing, about one-third of the scrap copper will be returned to the mall as refined copper, while the remaining two-thirds will be reused in non refined copper or copper alloys.

The possibility of interspersing pollution is high due to chemical decontamination, especially when it comes to the generation of secondary waste or when using circular decontamination. When implementing chemical methods for surface cleaning, due to the use of various chemical reagents and corresponding specialized equipment and power, appropriate operating cost support is required.

Scrap copper is one of the main materials for refining copper, including old and new scrap copper. Old scrap copper comes from high-rise buildings and underground pipelines discarded by old equipment and machines; The new scrap copper comes from copper shavings discarded by processing plants (the output ratio of copper materials is about 50%).

Generally, the supply of scrap copper is relatively stable, and scrap copper can be divided into miscellaneous copper (with a grade of over 90%) and yellow miscellaneous copper (including copper materials (old motor circuit boards); Copper produced from scrap copper and other similar materials is also known as recycled copper.

Overall, the classification of scrap copper is based on the content of pure copper,

Bright copper (Cu>99%)

#1 copper (Cu 97%)

#2 Copper (95% -96%)

Motor copper (92-94%): Generally refers to the copper on the motor inside the motor.

Purple impurity copper (79-81%)

Smelting grade copper (Cu90-92%)

Copper bricks (CU93%)

Fire burning line (95-97%)

Purple copper edge material

H59 yellow impure copper. Brass is represented by+H; (Yellow) indicates items such as H80, H70, H68, H59, etc.

In fact, they are all called purple copper, but the type that is more commonly traded in the market is called purple mixed copper, with a copper content of about 80%. There are also scrap metal varieties that are more commonly traded in brass. Generally, brass is 59% pure copper, with zinc as the main component. This type of copper is also called yellow mixed copper
