As a very important source of raw materials in the copper industry, scrap copper plays an extremely important role in the production process of the copper industry. There are two types of scrap copper according to its origin, one is old scrap copper, which is an item that is thrown away after use, such as old scrap copper that is thrown away or disassembled from old buildings and transportation systems. The other type is new scrap copper, which is the scrap produced in the copper industry production process. Generally speaking, new scrap copper accounts for more than half of the scrap copper used for recycling. Scrap copper is one of the main raw materials for refining copper, including old scrap copper and new scrap copper. Old scrap copper comes from high-rise buildings and underground pipes discarded by old equipment and old machines; new scrap copper comes from copper shavings discarded by processing plants. At this stage, the supply of scrap copper is relatively stable, and scrap copper can be divided into miscellaneous copper and brass miscellaneous copper; while copper produced from scrap copper and other similar environments is also called recycled copper.
