The difference between waste circuit board recycling and other garbage recycling is that waste circuit board recycling can be completely dissociated, recycling effective resources, and will not cause environmental pollution. To a certain extent, this is the need for the development of my country's electronic waste recycling technology and environmental protection industry, and it is also the level of my country's environmental protection recycling industry, which represents the progress and improvement of a country's mechanical technology. The application of circuit board recycling equipment in electronic waste recycling has freed my country's electronic waste separation technology from traditional chemical separation methods, reduced environmental pollution, and promoted the development of an environment-friendly society. On the other hand, circuit board recycling equipment can make the recovery rate of raw materials higher, save labor costs, and bring good economic benefits to enterprises.
Electronic circuit board waste is not an ordinary waste, but a resource-rich aggregate containing precious metals such as gold, silver, platinum, and rhodium, and alkaline metals such as copper, iron, and nickel. According to statistics, among 1 ton of electronic circuit boards randomly collected, about 272 kg of plastic, about 130 kg of copper, about 0.45 kg of gold, about 41 kg of iron, about 30 kg of lead, about 20 kg of tin, about 18 kg of nickel, about 18 kg of antimony 10 kg. Therefore, electronic waste circuit boards can be regarded as a kind of "high-grade" ore, with a high degree of resource recovery and high economic benefits. With the depletion of the earth's mineral resources, whether it is from the perspective of garbage disposal and reducing environmental pollution, or from the perspective of recovering valuable metals and alleviating the contradiction between supply and demand of resources, it is of great practical significance to recycle e-waste as a secondary resource. .
In electronic waste, recycling circuit boards, although difficult, has high economic value. The circuit board is equivalent to dozens to hundreds of times the metal grade in ordinary minerals, and the metal content is as high as 40% or more, mostly copper, in addition to gold, tin, nickel, lead, silicon, etc. , there are many rare metals, and the content of abundant minerals in nature is usually only 3-5%. In addition, non-metallic waste residues of discarded circuit boards can be used as building materials. At the same time, materials such as solder and plastic on waste circuit boards are also important resources that can be recycled.
