  • CPUs have gold and plating on its pins and gold wires inside them
  • RAMs have gold plating on its fingers and gold wires inside the chips
  • PCBs, an important component of electronic products, predominantly use metals such as copper and gold.
  • Electronic chips used in computers, cell phones and other electronic items have some silver also along with gold.
  • One of the options of process for gold extraction involves first pulverising the e-waste into a paste. Then, depending on the concentration of gold in this metallic paste, scientists used appropriate processes such as solvent extraction, electroplating or cementation to isolate the yellow metal.
  • For gold recovery from motherboards CN process, aqua regia, nitric process, pyrolysis & hydrometallurgy can be used
  • Different CPUs have different quantity of gold in them
  • 1 Kg. SIM cards of cell phones have 1.75 grams of gold.
