Da Xing waste recycling, recycling Dongguan gold-plated, gold-plated Recycling scrap materials provided by the Da Xing. We are Dongguan City of scrap material recycling companies (www.dxhphs.com) located at: Dongguan specializes in: scrap metal recycling, waste plastic recycling, e-waste recycling, industrial waste recycling, building new technology to make e-waste into resources, "mine "1 ton of used computer can be extracted from 660 grams of gold, 1 kg silver, 150 g of copper, nearly two kilograms of precious metals and other resources; 1 ton of old mobile phones can be extracted from 400 grams of gold, 2.3 kilograms of silver, 172 g copper. Today, the method for processing electronic waste: waste is fed into the circuit board level crusher, crushed into 1-2 cm of particles; these particles in the secondary crusher again "downsizing" of less than 0.8 mm into a fine powder. Then, they all enter a high-voltage electrostatic separator "Accept assessment", by the action of high-voltage electrostatic and non-metallic powder is a roller shaft firmly suck, and metal powder were "dumped" from the large forces. Finally, the metal powder was isolated by vacuum distillation of various components of gold, copper, iron and other liaobu gilded recycling, non-metallic powder can be made into renewable extruded sheet - this way, all of the waste can be "active aging." a. How effective is treatment? Typically South City gilded recycling, mining 1 ton Jinsha about 5 grams of gold can be extracted, and according to estimates, powder per ton of waste computer after the destruction, the gold content is 660 g. Moreover, from one ton of scrap computer can also extract 1 kg of silver, 150 g of copper, nearly two kilograms of rare metals and other resources. From one ton of old mobile phones can be extracted from 400 grams of gold, 2.3 kilograms of silver, 172 g copper. When an American throw away a computer, it will eventually go? Recently, a United Nations report noted that the recovery of Dongguan gilded world produces about 70% of electronic products eventually flow into China in the form of waste, including waste TV, refrigerator, washing machines, computers, mobile phones and other electronic products and components. They are mostly produced in China, after the completion of the mission around the world, ultimately, "returning to their roots." Most e-waste recycling into China through illegal channels gilt, which has formed a complete industrial chain. Upstream industry chain, is garbage exporting agents. In the United States, East, West Coast, waste export agent company will sell e-waste to developing countries. For American companies, processing one ton of e-waste takes 400-1000 U.S. dollars, while exports cost only 10-40 U.S. dollars per ton. Therefore, the garbage exports to cost much more. According to Silicon Valley "to prevent Toxics Coalition," the survey report, the United States has 50% to 80% of electronic waste is exported to Asian countries, mainly in China every year. Another big country electronic products to Japan, but also the source of e-waste exports. Japan every one million units of waste home computer, recovered by the provisions of the channel is less than 10, most of the other inflows to developing countries. The next part of the industry chain, China and other junk traders in developing countries. After docking them and sellers, these e-waste in the name of a new computer or industrial waste declaration, shipped by sea to Hong Kong or other ports, then sent to the mainland via e-waste land transport. Many of the middlemen involved in the process are well versed in Chinese import and export of Sino-US trade policy.
