Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·The Role of Gold in Electronics Before we reveal why gold is used in electronics let s talk about how it s used Electronics aren t made entirely of gold Rather the precious and expensive metal is used for specific components such as connectors switch contacts relay contacts and wires High Electrical Conductivity
·equipment such as in computers mobile phones and cars Computers have plug in printed circuit boards with gold plated finger connectors and the various parts of the computer monitor printer etc are connected by plug in sockets which usually have gold plated pins and sockets Some examples are shown in Figure 1
·Electronics such as smartphones tablets laptops and even gaming consoles contain gold plated components These components such as circuit boards connectors and memory chips are carefully designed with a thin layer of gold to enhance conductivity and prevent corrosion By carefully dismantling old computers you can uncover a treasure
·In mobile phones Smartphones contain several components that may contain gold such as the printed circuit boards connectors and pins Gold is used due to its excellent conductivity and durability In hard disk drives HDDs The hard drives used in computers usually have gold plated connector pins and internal circuitry
This gold plating is usually around % pure gold 24 karat gold as the high purity ensures optimal conductivity and corrosion resistance for the electronic components However it is essential to note that the gold plating is extremely thin and not comparable to the gold used in jewelry or other applications measured in karats
EScrap such as whole computers or individual components from computers contain gold palladium and other precious materials Computer circuit boards have gold and other precious metal traces in densities comparable to mined ore There is enough valuable material to make refinement profitable on even a moderate scale
·Gold Trivia Gold is one of the few elements found in its native state Gold is the most malleable and ductile metal One ounce of gold can be beaten to 300 ft 2 or stretched into a wire 2000 kilometers long 1 μm thick ; Gold s melting point is an assigned value which serves as a calibration point for the International Temperature Scale and International Practical
Desktop Computers also known as Desktop PCs are types of computers that are designed to remain in a single location They have larger boxier form factors than Laptops Tablets and AIO PCs and are designed to have separate Keyboards & Mice Monitors and other peripherals plugged in Laptops Tablets and All In Ones on the other hand include many of these
·A computer is an electronic device that accepts data performs operations displays results and stores the data or results as needed It is a combination of hardware and software resources that integrate and provide various functionalities to the user Hardware is the physical components of a computer such as a processor memory devices monitor
·Sounds almost impossible from three boards even old server boards even if they were from 1996 & had pentium pro processors the gold standard of 1 gm each being they don t have more than 4 5
·A new method for recovering high purity gold from discarded electronics is paying back US$50 for every dollar spent according to Swiss researchers who found their all important gold filtering
·Recovery of precious metals from computer scrap is a highly specialized process that involves disassembly of the computer separation of precious metal bearing components and a series of chemical processes to recover the metals
·$begingroup$ Gold is only used for contacts because unlike silver and copper gold s surface doesn t oxidize Gold is very expensive so it is only used when necessary As for semiconductor materials it s not so much a matter of which material Si or Ge has better electrical conductivity
·Computers have the most gold in them Less complex devices like camcorders and microwaves etc have at least a small quantity of gold in them too Copper being more chemically active and less ductile is not favored in making the connectors used in technology These components must be more robust and long lasting

Gold components found in many different types of Integrated Circuit packages NTK List of Ceramic CPU s that have the Highest Gold Content Intel Pentium Pro Processor with Gold plated Lid as is the case in many of today s mobile devices such as laptop computers tablets and smartphones which require the CPU to have the lowest profile
Removing the gold does take a little time and effort but once removed the work that it required will be well worth it When you hear about local businesses accepting old non working computers from people that just want to get rid of them these companies perform the same technique for removing the gold that you saw in the video above
·There s gold platinum and other valuable materials in every phone the hard part is getting it out From phones to computers Guiyu in China processes much of the world s e waste in
·Old Mainframe Computers Mainframe computers that were made by IBM several decades ago sometimes occupied an entire room They were packed with dozens of printed circuit boards Old VCRs contain printed circuit boards that contain gold So do old stereo components game consoles and other boxy electronic devices
