What is the easiest way to get gold out of electronics?
The Canadian researchers' alternative is a solution of acetic acid and an oxidant — a nontoxic technique to dissolve gold, which is stripped from circuits in about 10 seconds, leaving intact copper, nickel, iron, and other metals in printed circuit boards.
How do you get gold off circuit boards?
Strip out the boards In another container, mix two parts hydrochloric acid and one part weak hydrogen peroxide (a concentration of three per cent). Pour this mixture over the circuit boards so they are completely submerged. Wait for a week, giving the vessel a stir every day with a glass or plastic rod.
Can you burn gold out of circuit boards?
Gold, silver, platinum and other precious metals do not burn. When scrap that contains them is reduced to ash by burning, precious metals are typically left behind and can be easily identified and recycled.
Does gold dissolve in vinegar?
A: Because pure gold is a stable element that does not react with oxygen, it is unaffected by a white vinegar cleaning solution. This means gold will not change color, become crystalized, or break down. However, because vinegar is an acid, it can dissolve dirt, grime, and build-up on your jewelry.

How much gold is in an average circuit board?
The gold content present in the PCBs depends on the type of PCB used in each device, and may vary between 140 and 700 g of gold per tonne of PCB. The gold content found in these PCBs is much higher than the average levels found in gold ore, which is currently 5-10 g of gold per tonne of ore.
Can you burn gold with a lighter?
How to Test If Gold Is Real with a Lighter. The first test is also the easiest test: try to burn your gold. If it's real gold, it will get brighter as you apply the flame but it won't actually catch fire and burn. If your gold piece starts to smoke or gets darker, you likely have imitation gold.

Does hydrogen peroxide dissolve gold?
175-176 C1995 wrote: Hydrogen Peroxide and hydrochloric acid will dissolve gold. This is used in several refineries. One refiner reported that the recovery of PGMs was much improved when hydrogen peroxide rather than nitric acid was the oxidizer.
Does baking soda dissolve gold?

How to Extract Gold From Electronics - Instructables
In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment. This process is not supposed to be lucrative.
Be Careful When Picking Hazardous Chemicals
One of the most important aspects to consider when extracting gold from e-waste is safety. This begins with developing a plan for storing and using hazardous chemicals during extraction, but it also includes understanding how these chemicals could affect you or your community if they were spilled or mishandled.
Prepare Materials and Safety Equipment
Once you have assessed the hazards associated with the chemicals and equipment you will be using, it is important to gather all of the necessary supplies and safety gear. This includes items like a face mask, gloves, goggles, and lab coat to protect your skin and clothes from any harmful substances.
Follow Safe Handling Procedures
In addition to wearing personal protective equipment (PPE), other safe handling procedures should be followed when working with hazardous chemicals. These include avoiding contact with eyes and skin, never eating or drinking while working, washing hands thoroughly after use, and properly storing chemicals away from children and pets.
Prepare Electronics for Gold Extraction
After you have carried out the necessary safety measures, it is time to start extracting gold from your e-waste. First, disassemble all of your electronics into individual pieces by following manufacturer instructions (if possible), and sorting them into plastic, metal, and glass waste bins.
Clean Off PCBs
The next step is to clean off any residual plastic, metal, or glass from the PCBs. You can do this by using a solvent like acetone that will dissolve most non-metallic substances. Just be sure to avoid getting the acetone on any of the electronic components themselves or on your skin because it is highly flammable and toxic.
Create The Etching Solution
Now it is time to create the etching solution that will be used to remove the gold from the PCBs. This can be done by dissolving a small amount of cyanide in water (be sure to use protective gear when handling cyanide). The concentration of cyanide in the solution will determine how much gold is removed from the PCBs.
Extract the Gold Foils
With the etching solution prepared, it is time to start extracting the gold foils from the PCBs.
How to recycle PCB board?
Firstly, these PCB boards will become small particles through the shredder and crusher. Then these small particles will go through the magnetic separator, which will remove the iron.
