- Using technology, it is possible to recycle gold worth lakhs of
rupees from junked computer monitors, motherboards, televisions and
other electronic products.
- 43% of total production of gold in the
whole world is used in electronics
- 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.
