1, now usually use motherboard about 300 to 500 yuan. The computer is a desktop computer, or a notebook, is a brand machine or assembly machine, if the motherboard is broken, it is generally a computer that has been used for a long time, and the electricity at that timeThe brain chip and the motherboard are relatively lower than the current version, and the price is about 700 to 1200. Notebook motherboard is more expensive, to configure higher, the motherboard price is higher, the desktop will be slightly lower.
2. The recycling price of old computers is usually between 500 and 2000 yuan. Specifically, the motherboard is worth about 120 yuan, the CPU is about 80 yuan, the memory is about 160 to 180 yuan, the chassis power supply is about 100 yuan, and the other parts are about 200 yuan in total, and the recovery price of these parts is about 500 yuan. If the parts are taken apart and sold separately, the price may be higher than if they are recycled as a wholeIt's a little higher. The recycling price will vary depending on the configuration and age of the computer.
3, old computer recycling motherboard 120 yuan, CPU about 80 yuan, memory 160-180 yuan, chassis power supply about 100 yuan. Other parts are around 200 yuan. It all adds up to about 500 yuan. If it is recycled, the price of the parts sold separately will be more expensive than the overall recycling.
4. The recycling price of old computers is usually between 500 and 2000 yuan. Specifically, the motherboard may be worth 120 yuan, the CPU about 80 yuan, and the memory bar 160To 180 yuan, chassis and power supply about 100 yuan, other parts total about 200 yuan, these add up to about 500 yuan. If the parts are broken down and sold separately, the price may be slightly higher than the whole recycling. The recycling price of the computer will vary according to the configuration and use condition.
5, the recycling price of old computers is about 500 to 2000 yuan. The recycling price of the specific components is as follows: the motherboard is about 120 yuan, the CPU is about 80 yuan, the memory is 160 to 180 yuan, and the chassis power supply is about 100 yuan. Other parts total about 200 yuan. Overall, the recycling price of an old computer is about the sameIt's around 500 yuan. If the parts are sold separately, the price may be slightly higher than the whole recycling.
6, the computer city recycling bad motherboard is basically sold by catty. According to the color of the motherboard and the degree of damage, the price is not the same. The general old motherboard price is about eight yuan. The price of the new, full-solid capacitor motherboard may be ten or twenty yuan.
Yuan/jin. 1 catty mobile phone card can refine 0.25 grams of gold, depending on the region, the price will vary. The chip of the mobile phone card is not gold. The gold contained in the mobile phone is generally located on the motherboard and the chip. But the content is very small, a ton of mobile phones can be extracted 150 grams.
Apple card stick machine merchants can be recycled, but the recycling price of the card stick machine is very high. Of course, the specific color and the health of the battery depend on the price of the Apple card sticker machine is an important factor, if the appearance has obvious bumps or the screen has scratches, the price of the sale is relatively low, and the card sticker machine also has certain hidden dangers, so the price of the business in the recycling of such a machine is relatively low.
Many components of the mobile phone motherboard contain gold, motherboard lines, chips, IDE interfaces, PCI Express slots and other interfaces, processor sockets, etc., in these interfaces are often covered with a few microns thick gold layer. In addition, the SIM cards we use also contain gold. When using mobile phones, it is recommended to make calls in areas with good signal as far as possible. Reduce talk time in areas with poor signal quality.
Microelectronics manufacturers; (Waste chip, waste IC, sim card chip, smart chip). Integrated circuit manufacturers; (All kinds of waste functional equipment,The market recycling price of used circuit boards is about 3 to 20 yuan per catty. At present, the basic market recycling price of waste circuit boards is about 8 yuan per catty. To calculate that a ton is equal to 2000 jin, the price of each ton of waste circuit board is about 7600 yuan.
Recycle circuit board 3-20 yuan or so a catty. Used circuit boards, the current basic market recycling price is about 8 yuan per catty, a ton is equal to 2000 catty, 8 times 2000 is a ton of money about 7600 yuan.
IndividualRefining gold can be a way to generate income, but the process is complex and challenging. First of all, refining gold requires specialized knowledge and skills, as well as skilled operation of chemical reagents and high-temperature and high-pressure equipment. Improper operation may not only pose a threat to personal safety, but also lead to environmental pollution. Second, it is expensive for individuals to refine gold.
Personal gold refining can be used as a way to make money, but the process is quite complex and challenging. First of all, personal gold refining requires professional knowledge and skills, as well as a large investment of time, money and energy. Gold extractionInvolving the use of chemical reagents and high temperature and pressure equipment, improper operation may cause injury to the operator or pollution to the environment. Second, refining gold by individuals is not only dangerous but also expensive.
Make money. Refining gold is not only a technology, but also a lucrative field. It's also less complicated, easier to learn, and easier to make money. The method of extracting gold from gold-plated waste products is to dissolve gold with strong acids and toxic chemicals such as sodium cyanide, potassium cyanide, hydrogen peroxide, sulfuric acid and hydrochloric acid.
Refining gold can make money, but only if you master the corresponding technology and market trendsA lot. In the gold market, the price fluctuations are large, and the market demand is also large, so you can earn the difference by refining gold. However, it is important to note that if the market trend is not conducive to the price of gold, or you are not skilled enough, there may be a risk of loss.
Refining gold is a very lucrative business, but it is also a very difficult business. To extract gold is to extract a small amount of gold coating from used electronic parts or pins. Because some special parts must be painted with gold to normal use, such as train pins, aviation pins, mobile phone internals and so on.
