How To Recover Gold From Electronics

How To Recover Gold From Electronics



As technology continues to advance at a rapid pace, electronic devices have become an integral part of our daily lives.

However, what many people may not realize is that these devices often contain small amounts of precious metals, including gold.

Gold is used in electronic components due to its excellent conductivity and resistance to corrosion.

So, when these devices reach the end of their life cycle or become obsolete, there is an opportunity to recover gold from them.

Recovering gold from electronics is not only an environmentally friendly way to dispose of electronic waste but also a way to extract valuable resources that can be reused or sold.

While the process may seem daunting at first, with the right knowledge and techniques, you can successfully recover gold from electronic devices.

In this guide, we will explore the process of recovering gold from electronics step by step. We will discuss the types of electronics that contain gold, the methods used for extraction, and the safety precautions to take during the process.

Whether you are an enthusiast looking to embark on a gold recovery project or someone interested in understanding the process, this guide will provide you with valuable insights and instructions to help you recover gold from electronics effectively and responsibly.

So, let’s dive into the world of electronic gold recovery and unlock the hidden treasure within our electronic devices.

How Do I Recover Gold From Electronics?

Gold is used in electronic components due to its excellent conductivity and resistance to corrosion. When electronic devices reach the end of their life cycle or become outdated, they can be a valuable source of gold that can be recovered and reused.

Not only does this process help reduce electronic waste, but it also allows for the extraction of valuable resources.

Recovering gold from electronics may seem like a complex and intimidating task, but with the right knowledge and techniques, it can be done effectively.

In this article, we will guide you through the process of recovering gold from electronics, step by step.

1. Gather Your Electronic Devices.

Start by collecting electronic devices that contain gold. These can include old computers, cell phones, circuit boards, and other electronic equipment.

It’s important to note that different devices contain varying amounts and types of gold, so it’s worth doing some research to identify the most valuable sources.

2. Safety Precautions.

Before starting the gold recovery process, it’s crucial to take proper safety precautions. Wear protective gloves, safety goggles, and a face mask to protect yourself from potential hazards. Work in a well-ventilated area to minimize exposure to harmful chemicals and fumes.

3. Disassemble the Devices.

Carefully disassemble the electronic devices to access the components that contain gold. Use appropriate tools, such as screwdrivers or pliers, to remove the parts without damaging them.

Pay attention to circuit boards, connectors, and chips as these are the components most likely to contain gold.

4. Sort and Separate.

Once you have the components, sort and separate them based on their gold content. Circuit boards and connectors usually have a higher concentration of gold compared to other parts.

Remove any non-gold components, such as plastic or other metals, and set them aside for proper recycling.

5. Chemical Extraction.

The most common method for recovering gold from electronic components is through chemical extraction.

There are several methods to choose from, but one of the most widely used is the “acid stripping” method.

This involves using a mixture of hydrochloric acid (HCl) and nitric acid (HNO3), commonly known as aqua regia, to dissolve the gold.

6. Dissolving the Gold.

In a well-ventilated area or under a fume hood, carefully mix the hydrochloric acid and nitric acid in a ratio of 3:1.

Place the electronic components containing gold into a glass container and add the aqua regia solution. The acids will dissolve the gold, leaving other non-gold components unaffected.

7. Precipitation.

Once the gold has dissolved, the next step is to separate it from the acid solution. Precipitation is commonly done by adding a chemical reducing agent, such as sodium metabisulfite or oxalic acid, to the solution. This causes the gold to precipitate as a solid, which can then be filtered and washed.

8. Refining.

The precipitated gold will still contain impurities and other metals. To refine the gold further, it can be melted down using a torch or furnace. This process helps remove any remaining impurities, resulting in a purer form of gold.

9. Gold Recovery.

Finally, the purified gold can be cast into ingots or used for other purposes. If you’re not comfortable refining the gold yourself, you can consider selling it to a reputable precious metal refinery or jeweller.

It’s important to note that gold recovery from electronics requires knowledge, experience, and caution.

If you’re new to the process, it’s advisable to start with small and simple electronic components before moving on to more complex devices.


Recovering gold from electronics is not only an environmentally responsible way to handle electronic waste but also a chance to extract valuable resources.

By following the steps outlined in this article and taking appropriate safety precautions, you can successfully recover gold from electronic devices and contribute to a more sustainable future.

So, start exploring those old gadgets and unlock the hidden treasure of gold within them.
