Is Recycling Gold from Old Computers Still Viable?

Click For Summary

Discussion Overview

The discussion revolves around the viability of recycling gold from old computers, focusing on the presence of gold in electronic components, the risks involved in the recycling process, and the historical context of gold usage in electronics.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants mention that companies exist that reclaim gold from old computers and other electronic components.
  • One participant warns about the health risks of attempting to recycle gold personally, citing potential lead poisoning from solder.
  • Another participant notes the current market price of gold, providing a specific value per troy ounce.
  • It is suggested that the amount of gold in old computers may be minimal, with gold primarily used in specific components like video contacts.
  • One participant claims that CPUs and integrated circuit (IC) chips are significant sources of gold, highlighting its use in internal wiring and contact points.
  • A historical perspective is offered, indicating that gold was more commonly used in electronics in the 1960s and 1970s, with modern designs reducing the need for gold due to advancements in solder technology.
  • Concerns are raised about the thickness of gold plating on connectors, which is described as being only a few nanometers thick.

Areas of Agreement / Disagreement

Participants express differing views on the amount of gold available in old computers and the risks associated with recycling it. There is no consensus on the viability of personal recycling efforts or the economic benefits of such activities.

Contextual Notes

Limitations include assumptions about the quantity of gold in various components, the health risks associated with recycling methods, and the historical context of gold usage in electronics.

Is in old puters? i have read about a company that re claims gold from them and other electronic components.
 
Computer science news on Phys.org
If you're thinking of doing this yourself, you'll probablly die of lead poisoning from the solder before you become rich.
 
It's been around $900 US per troy ounce...1 troy ounce = 31.1 grams.
 
there's prolly not much. After doing a fair amount of tech destruction/creation/exploration, I haven't seen much gold, its only really used for like video contacts and other things that require especially good connection. An add on would be how much silver (best conductor) would there be.
 
As far as I know the biggest place that gold is used is on CPUs and any type of IC chip. For CPUs it is pure gold for the internal wires connecting the silicon chip to the external contacts, and usually gold plating for the contact points (LGA type chips) or for the pins. As for the IC chips it is usually just the internal wires.
 
It used to be used a lot more common in the 60/70s. Surface mount components allow much shorter lead lengths so you don't have to be as concerend about conductivity. Modern solder design also reduces the corrosion effects.

You do still find gold plating on connectors but it's anly a few nm thick!
