China's copper resources are inherently inadequate and cannot fully meet the needs of national economic development. Since the 1980s, the shortage of copper demand in China has been supplemented and solved by imports. It is precisely because of this that the Chinese government and related companies have always attached great importance to the recycling of waste copper. Before the 1990s, the materials sector and the national supply and marketing cooperative system in the country to establish a wide range of scrap metal and waste recycling network, and waste recycling scrap copper included in the mandatory plan.
After the 1990s, with the establishment and gradual improvement of the socialist market economic system and the continuous development of the national economy, the scale of copper consumption has grown rapidly, so the demand for scrap copper has increased significantly, and the supply of scrap copper has been supplied. Expanded from abroad to abroad. Imports of scrap copper began to increase year by year. The varieties of domestic imported waste copper are mainly 2# scrap copper, used wires, cables and a large number of waste motors with low copper content. The waste copper imported from China mainly comes from the United States, Japan, the European Union and Russia, of which the largest import volume from the United States accounts for 40% to 50% of the total imports.
The content of metal in used household appliances accounts for about 75%. Therefore, metal has become the main target for the recycling of used home appliances. Compared with the recovery of metals (including precious metals and base metals) in microelectronics, the recovery of base metals in used household appliances is generally carried out by fire or physical processes. The order of recovery is generally iron and iron alloys, copper, aluminum , lead , tin, etc. metal.
The recycling of copper materials, waste household appliances contain a large amount of copper, mainly in various types of wires, condensers, strips, motors, circuit boards and electronic components. The household appliances and electronics industries use almost all varieties of copper, with the largest use of wire, strip and electrolytic copper foil. Therefore, when copper is recovered from used household appliances, the variety and form of copper-containing scrap are complicated. Before recycling copper in household appliances, it is necessary to understand the knowledge of copper.
Copper wire is the largest variety of copper materials, the most widely used varieties, mainly used for wire and cable conductors, enameled wire, tinned wire and so on.
The main varieties of copper-containing alloy wire are brass wire (including ordinary brass wire, brass flat wire, lead brass wire, etc.), mainly used for screws, hardware, zippers, jewelry, bicycle banners and so on. The use of pipes is relatively concentrated and is mainly used in the manufacture of air conditioning coils, condensing pipes and water supply and drainage pipes. The strips are used in a wide range of applications and are mainly used in the manufacture of transformers, automotive water tank fins, electronic copper strips and ordinary brass strips.
Copper strips used in household appliances are mainly electronic copper strips and ordinary brass strips. The electronic copper strip is a copper-iron- phosphorus alloy, which is mainly used for integrated circuit plug-ins. The electronic copper strips of the grades c19200 and c19400 have exceeded 10,000 tons in domestic use. Ordinary brass belts are mainly used to manufacture parts and decorations for electrical appliances, automobile instruments, various heat sinks, communication equipment and computers.
Electrolytic copper foil is mainly used in the production of printed circuit boards in the electronics industry. The product requirements are high and the technical difficulty is large. The development trend is ultra-thin and double-sided processing. With the rapid development of the information industry, its usage is increasing. The largest variety of bars is lead yellow stick, which is mainly used in the manufacture of various machinery, electrical appliances, hardware and other parts. The product has low requirements on copper grade and can be produced by scrap copper.
With the depletion of copper resources, the recycling of copper-containing scrap has attracted the attention of all countries in the world, not only because of its high value in recycling and recycling, but also because people pay more and more attention to environmental protection issues. Strengthened the recycling of waste copper.
The domestic waste copper recycling industry is characterized by a wide range of points. From the perspective of the existing recycling methods of large and medium-sized enterprises, they can be roughly divided into four types:
A large state-owned smelting and mining conglomerates, such enterprises recycling of scrap copper is mainly to complement its own raw materials (copper concentrate) is insufficient to meet the needs of the production capacity of the play, such as white silver Nonferrous Metals Company, Daye Nonferrous Metals Corporation, Jiangxi Copper Company, Tongling Nonferrous Metals Corporation, etc.;
2. Enterprises that purchase copper concentrates and waste copper to meet production needs, such as Chongqing Smelter, Yunnan Smelter, Zhuzhou Smelter, Shenyang Smelter, etc.;
3. Crude copper and waste copper are remelted, refined and electrolyzed to meet the production needs, such as Wuhan Smelter, Taicang Electrolytic Copper Plant, Changzhou Dongfang Xinyuan Copper, Ningbo Jintian Copper Company, Luoyang Copper Processing Factory, Guangzhou Copper factory, etc.;
4. Enterprises that recycle waste copper for production, such as Tianjin Electrolytic Copper Factory (with some crude copper).
In addition to the above-mentioned large and medium-sized copper smelting and processing enterprises, there are still hundreds of small copper smelters in China. Most of these enterprises belong to collective or private enterprises using waste copper as raw materials, and they are recycled by simple production process (cupola, small reverberatory furnace, etc.). Most of the products obtained are crude copper (commonly known as black copper). Among them, some companies' final products are copper sulfate.
In short, the blister copper produced by such enterprises generally contains high impurities and cannot be directly used for the production of processed copper. These products require one-step refining and electrolysis. In the traditional production and operation process, the main distribution center for domestic waste copper recycling and regeneration has gradually formed.
According to the survey, the recycling and recycling of domestic waste copper is mainly concentrated in five provinces and cities such as Hebei, Jiangsu, Zhejiang, Guangdong and Shanghai. In Jiangsu Province and Shanghai, not only are there a large number of companies producing recycled copper, but also the output of recycled copper. At present, the distribution and recycling of domestic waste copper is mainly concentrated in Qingyuan and Xin'an in Hebei Province, Shaoxing, Ningbo and Guangdong in Zhejiang Province.
At present, there are two main methods for producing recycled copper in China: the first type is to directly smelt waste copper into different grades of copper alloy or fine copper, so it is also called direct utilization method; the second type is to use copper to pass the fire method. The cast anode copper is processed, then electrolytically refined into electrolytic copper and other valuable elements are recovered during the electrolysis process. When using the second type of method to treat copper-containing scrap, there are usually three different processes, one-stage, two-stage, and three-stage.

The major western countries are the world's major copper consumers, and they are also the major producers of waste copper and the major countries of recycling. The direct use of scrap copper in western countries is higher, but the output of recycled copper is lower. This is because the environmental laws of major western countries are very strict, and the punishment will be heavy when pollution is caused. The recycling and remelting of recycled copper will cause a certain degree of local pollution, and the waste copper in these countries is often sold abroad. In fact, this practice is pollution transfer.
