Recycling Gold from Old Computers: A Company's Journey

In summary, the conversation discusses the potential of reclaiming gold from old computers and other electronic components. However, it is mentioned that this process can be dangerous due to the lead poisoning from the solder. The value of gold is also mentioned, with an ounce being equivalent to 31.1 grams. The participants also discuss the common uses of gold in CPUs and IC chips, primarily for internal wires and contact points. It is noted that the use of gold in electronics has decreased with advancements in technology, but it can still be found in small amounts on connectors.

Is in old puters? i have read about a company that re claims gold from them and other electronic components.

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.

Theres 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!
 

1. How does the process of recycling gold from old computers work?

The process of recycling gold from old computers involves several steps. First, the old computers are disassembled and the components are sorted. Then, the circuit boards are shredded and the gold-bearing components are separated using various techniques such as chemical treatment or electrolysis. Finally, the extracted gold is purified and turned into usable form.

2. Why is recycling gold from old computers important?

Recycling gold from old computers is important for several reasons. Firstly, it helps to reduce the amount of electronic waste that ends up in landfills, which can have harmful environmental effects. Additionally, extracting gold from old computers reduces the demand for newly mined gold, which can have negative impacts on the environment and local communities. Recycling also helps to conserve natural resources and reduce energy consumption.

3. Can all types of old computers be recycled for gold?

While most old computers contain small amounts of gold, not all of them can be efficiently recycled for gold. Some older models may not have enough gold content to make the process economically viable. Additionally, certain types of computers, such as those used in specialized industries, may have different components and may not be suitable for gold recycling.

4. Is it cost-effective for companies to recycle gold from old computers?

The cost-effectiveness of recycling gold from old computers depends on various factors, such as the quantity and quality of the old computers, the efficiency of the recycling process, and the current market value of gold. In some cases, it can be more cost-effective for companies to sell their old computers for reuse rather than recycling them for gold.

5. What are the potential risks and challenges associated with recycling gold from old computers?

There are several potential risks and challenges involved in recycling gold from old computers. These include the proper disposal of hazardous materials, such as lead and mercury, which are found in some computer components. There may also be challenges in obtaining a steady supply of old computers for recycling, as well as fluctuating market prices for gold. Additionally, the recycling process itself may require specialized equipment and expertise, which can be costly for companies.
