Gold is used in electronics because it’s an excellent conductor of electricity and resistant to corrosion . It’s commonly found in:

  • Circuit boards
  • Processor chips
  • Connectors
  • Memory modules
  • SIM card slots

While the amount of gold in any single device is tiny — often just a few milligrams — when processed in bulk, it can add up.

🔍 Which Electronics Have the Most Gold?

Here’s a quick breakdown of devices and their gold content (approximate):

DeviceEstimated Gold Value per Unit
Old desktop computer motherboard$1–$5
Laptop motherboard$0.50–$2
Smartphones (iPhone, Samsung)$0.03–$0.05
RAM sticks$1–$3 per stick
Old game consoles$0.50–$2
Networking equipment (routers, switches)$0.10–$10 depending on size

🧪 How to Mine Gold from Electronics: Step-by-Step

There are three main methods to recover gold from electronics:

1. Mechanical Method (Non-Chemical)

Best for : Hobbyists and beginners who want to avoid chemicals.

Steps :

  1. Collect and sort electronics — focus on motherboards, RAM, and connectors.
  2. Remove gold contacts using a Dremel or small saw.
  3. Burn off insulation (optional) — use a heat gun or small torch.
  4. Separate gold from other metals using a magnet and manual sorting.

Pros :

  • No chemicals
  • Safe for home use

Cons :

  • Only recovers visible gold contacts
  • Not efficient for fine particles

2. Chemical Leaching Method

Best for : More serious hobbyists or small-scale recyclers.

Steps :

  1. Crush and grind the circuit boards into small pieces.
  2. Use aqua regia (nitric + hydrochloric acid) to dissolve gold.
  3. Precipitate gold using sodium metabisulfite or other reagents.
  4. Filter and dry the gold powder.
  5. Smelt into gold bars (optional).

Pros :

  • Recovers fine gold particles
  • Higher yield than mechanical method

Cons :

  • Involves dangerous chemicals
  • Requires proper ventilation and safety gear
  • Disposal of waste is regulated

3. Commercial Recycling

Best for : Large volumes of e-waste or those not interested in DIY.

Steps :

  1. Collect large quantities of electronics .
  2. Sell to a certified e-waste recycling facility .
  3. The facility will extract and refine the gold professionally.

Pros :

  • Safe and legal
  • Can earn money without doing the work

Cons :

  • Lower profit margin
  • Requires scale to be profitable

⚠️ Safety & Environmental Concerns

Mining gold from electronics can be dangerous if not done properly , especially when using chemicals.

Safety Tips:

  • Always wear gloves, goggles, and a respirator
  • Work in a well-ventilated area or fume hood
  • Never mix chemicals without proper knowledge
  • Label and store chemicals safely
  • Follow local and federal regulations on chemical disposal

💰 Is Mining Gold from Electronics Worth It?

Pros:

  • Can be a profitable side hustle if done at scale
  • Helps recycle e-waste and reduce landfill waste
  • Educational and fun for DIY enthusiasts

Cons:

  • Time-consuming
  • Low yield per unit
  • Legal and environmental risks if done improperly

📌 Bottom Line : It’s not a get-rich-quick scheme , but with the right setup and volume, it can be a profitable and sustainable hobby or small business .

Final Thoughts

Mining gold from electronics is a fascinating blend of chemistry, recycling, and entrepreneurship . Whether you’re doing it for fun, profit, or sustainability, it’s a rewarding way to give new life to old tech.

Just remember: safety comes first , especially when dealing with chemicals. If you’re not comfortable with the risks, consider working with a certified recycler or starting with the mechanical method.

So, next time you see an old computer or broken phone, don’t throw it away — you might just be tossing away a tiny gold mine.


FAQs

Q1: Can I really mine gold from old electronics?

Yes! Electronics like motherboards, RAM sticks, and connectors contain small amounts of gold that can be recovered through mechanical or chemical means.


Q2: How much gold is in a smartphone?

A typical smartphone contains about $0.03–$0.05 worth of gold , mostly in the connectors and circuitry.


Q3: Is it legal to mine gold from electronics?

Yes, but using dangerous chemicals may require permits or compliance with environmental laws. Always check local regulations.


Q4: What tools do I need to extract gold from electronics?

Basic tools include screwdrivers, pliers, a Dremel tool, gloves, goggles, and possibly chemicals if using the leaching method.


Q5: Is mining gold from electronics profitable?

It can be, especially at scale . However, for small volumes, it’s more of a hobby or educational project than a money-making venture.
