How are waste circuit boards treated
Scrap circuit board board board testing, scrap circuit board board board recycling, scrap circuit board board board refining technology is a comprehensive body to benefit from a technology that can provide a source of raw materials is a constant source, to be able to refine gold from electronic waste there are many materials, such as common scrap computer motherboard, cpu, memory sticks, sound cards, video cards, network cards, used mobile phones, printers, VCD, DVD, communication circuit boards, televisions, Digital electronics, refrigerators and washing machines, game consoles, learning machines, MP3, MP4 and many other materials have gold, silver and other precious metals. A ton of ore can only extract a few grams to dozens of grams of gold, while a ton of electronic waste can extract about 900 grams of gold, 1500 – 3000 grams of silver, 60 grams of palladium, 130 kilograms of copper, and some tin, nickel, and other metals. With the renewal of electronic products, the amount of electronic products scrapped is rising year by year, and discarded electronic waste can be found everywhere, as long as you contact the major scrap buying stations and repair shops, electronics factories. Immediately have a lot of resources. From the recovery than from the original mine in the cost of much lower, the economic benefits are very obvious.
In addition outside, the external materials of many used electronics as well as the internal metal components can be reused to generate even greater value. So, a lot of electronic waste is a small “gold mine”. It is an inexhaustible gold mine that never runs out.
Gold is traditionally the world’s universal preservation of hard currency, no shelf life, never worry about the sale of products, the country’s gold shops of all sizes are cash acquisitions, scrap circuit board testing there is gold can be refined, you can sell money. Look at the current market for a variety of investment projects to dazzle people, but the real investment less, high benefit is not much, scrap circuit board refining gold and silver technology market is really rare, not lost for a cold quick rich project.
As we all know, the pollution hazards of used home appliances are great. Such as used mobile phones, end-of-life computers, televisions, refrigerators and other electrical appliances, internal parts contain lead, nickel, cadmium, mercury and other toxic substances. According to relevant expert tests, a single button battery can pollute 600 cubic metres of water, while a single No.1 battery rotting in the ground can render a square metre of land useless. As you can see, the recycling management of used appliances has undoubtedly become an essential part of living in an environmentally friendly environment. At the national level, recycling management of used appliances is also being strengthened, with the development of an expanded scope of appliance recycling and the adoption of a subsidy policy for appliance recycling companies. However, the fact is that a number of enterprises are only playing the signboard of environmental protection, but the actual environmental protection can not be achieved: the main reason lies in the existence of a worldwide technical problem of waste circuit board recycling – the separation of mixtures.
