Waste electronic-Gold mountain and Silver mountain in city
Electronic waste, also known as e-waste, including all kinds of daily life abandoned after using the computer, communication equipment, household electrical appliances such as television, refrigerator, washing machine, as well as enterprises and institutions was eliminated in the process of production, office electronic instruments and meters, etc., and large quantity. , according to data of the national security council, according to a report out in America, 1998, 1998 computers in the next 10 years will reach 1.5 billion units number of computers that are to be eliminated.
Precious metals generally refers to gold (Au), silver (Ag), platinum (Pt), osmium, iridium (Os) (Tr), ruthenium (Ru), rhodium (Rh) and palladium (Pd), a total of eight kinds of metal, they are expensive and scarce resources. Because of the precious metals and their alloys with excellent electric conductivity, flexibility and high strength, are widely used in televisions, computers and mobile phones in common appliances such as circuit board assembly, capacitors and other electronic components.
With the speeding up of the electronic products renewal speed and increasing number of electronic waste, a large number of electronic waste containing precious metals failed to get effective recycling, not only wastes a large amount of precious resources, serious environmental pollution. Therefore, a scientific and reasonable recycling electronic waste of precious metals can save resources, reduce the production cost, and can effectively reduce waste emissions, to achieve the purpose of protecting the environment.
With the continuous development of electronic industry and economy as well as the electronic products renewal speed up, as raw materials for the production of one of the precious metal consumption is more and more big. Along with the increase in scrap electronic products, combined with the electronic waste processing difficulties, recycling utilization rate is not high, a large number of electronic waste containing precious metals to effective recycling, not only cause serious environmental pollution, also caused a lot of waste of valuable resources. Therefore, to strengthen the consciousness of prevention and control of electronic waste pollution legislation, scientific, reasonable and efficient recycling of electronic waste precious metals, such not only can save energy resources, reduce production costs, reduce waste emissions, and the purpose of protecting the environment,
Electronic waste recycling precious metals in the process of the treatment and follow-up two stages. Before processing mainly refers to the mechanical processing method, including dismantling, crushing, separation process; Subsequent processing, including precious metals extraction, pyrometallurgy, etc. Before processing can use our crusher,etc., subsequent processing, you can use our Precious metal recycling machine, etc. It is understood that a ton of gold extraction in electronic waste volume up to 130 grams, can bring us great harvest.
