The computer motherboard chip contains gold. 1 ton computer board can extract 1 kg gold. E-waste has high utilization value. Some used mobile phones, computers and other parts can pick out components containing gold, silver and copper to extract precious metals such as gold. About 1 30 kg of copper, 20 kg of tin and 0.45 kg of gold can be separated from1ton line card. Every 100g of mobile phone body contains copper 14g, silver 0. 19g, gold 0.03g and palladium 0.0 1g on average. The pins of memory and cpu must be gold, because these highly integrated chips are easy to heat and oxidize, so gold should be used. Just a small amount. Mainly in some chips of motherboard, CPU, graphics card and sound card.
Common circuit boards include CPU, computer motherboard, memory stick, graphics card and other computer accessories with high gold content. Judging from the level of gold content, the gold content of circuit boards in medical instruments is much higher than that of computer accessories, and some modules in precision instruments are also very high in gold content.
The common circuit boards in our daily life mainly include: televisions, computers, washing machines, refrigerators, air conditioners, mobile phones and other household appliances; It must be said here that the mobile phone board is a good raw material for refining precious metals, especially in old-fashioned mobile phones and computers, such as Nokia, Motorola, Philips, Bird and other old-fashioned mobile phones. Computer boards with high gold content, such as old-fashioned desktops, old-fashioned computers with floppy disks, and 98 systems.
According to statistics, each ton of used mobile phones contains about 280 grams of gold, 2000 grams of silver and 100 grams of palladium, of which copper and a small amount of platinum, iridium and rhodium are temporarily excluded. According to the annual elimination, these used mobile phones contain 2800kg of gold, 20000kg of silver and100kg of platinum group palladium. This is a treasure house of precious metals and platinum group metals.
Electric Hanjin should be a big switch, and his contacts used to be practical metal contacts with gold, which makes him a very good conductive metal, so that he can accurately transmit electricity through explosive high voltage, without power failure, fever or fire. It has a better conductive effect than any metal, so the general switch or contact with important parts requires the contact of the entrusted point.

There are also various connection plugs for the connection parts of the chip and the board. Generally, the higher the integration level, the higher the gold content. At most, the pins of CPU in used computers contain gold, and the backward chips are much more advanced, because the precision of gold plating process is different, and now they look basically the same.
Among household appliances, including household appliances, computers have the highest gold content, and small household appliances include these mobile phones.
Many household appliances actually contain some gold and silver, such as refrigerators, televisions, washing machines, power switches, and even many common appliances such as mobile phones, electric razors and computer memory chips.
Why do gold and silver appear on some household appliances? Gold is actually one of the few precious metals that will not oxidize. Gold has stable chemical properties and strong corrosion resistance. It does not react with oxygen even at high temperature in air, nor does it react with oxygen and sulfur at high temperature. Its chemical properties are very stable. If a layer of gold is electroplated on the power supply or contact point, it can play a long-term non-oxidation role and prolong the service life of electrical appliances. Therefore, in the yellow and flashing part of the power supply of waste household appliances, the appearance is actually plated with a layer of gold.
