Add some borax (available from chemists); this enables the gold to be melted at a temperature lower than 1,064C. When the borax begins to soften, add the gold flakes. Heat until the flakes melt into a gold bead. Now let it cool before chipping the gold out of the re-solidified borax.
Get protective gear. Be sure to wear a face mask, safety glasses, and industrial gloves to avoid breathing in the fumes released by the burning plastic.
Get a metal bin or tray, and put the circuit boards into it. Break the boards into smaller pieces so they burn faster.
Light the boards on fire.
Put out the fire.

Can you burn circuit boards for gold
Piles of burnt circuit boards and other electronic waste leave behind ashes and whatever gold they have. Dust and dirt collected from old jewelry factories can be burned, leaving ashes, as well as gold, silver and other precious metals.
What is the easiest way to extract gold from electronics
There are two industrial methods for recovering gold from e-waste: burning gold is high temperature, energy intensive, expensive, and releases toxic gases.
How do you extract gold from circuit boards without chemicals
In the meantime, let’s use salted apple cider vinegar and its method. First put the sea salt in a safe bowl, pour in the vinegar and stir until the salt dissolves. Vinegar and salt are a powerful but non-aggressive pickling solution needed to pickle tiny gold particles from computer parts.
How to extract gold from circuit boards
One board may not give you much gold, but having multiple boards also increases your chances of getting gold. When mining gold, you must use the tool of power. The curves must be carefully removed and processed in a clean area before the gold is removed.
How do you get gold out of electronics
All e-waste gold is turned into steel, where it can be rolled up like refined gold and set aside until you’re sure you have enough to clean up. Mix another cleaning solution. While you’ve recovered some gold from electronics, it may not be a pure rare metal.
How to extract gold from e-waste
Other traditional methods for extracting gold from e-waste. acid treatment. Approximate combinations of hydrochloric and nitric acids have proven to be useful products for recovering gold from e-waste. Other weak acids have also been successful in extracting gold because these acids can precisely position the gold, limiting its amount.
Is it possible to mine for gold in electronics
While dumping this gold has been a toxic and inefficient new proposition so far, experts now believe the new concept will make prospecting for gold from electronics batteries more feasible than ever. Gold is often found on regular circuit boards, especially under keyboards where its durability is a good asset.
How do you extract gold from electronics without chemicals
How to remove yellow gold from circuit boards without chemicals? Stock up on protective gear. Buy concentrated nitric acid. Place your trackboards in a glass jar to form a leg, eventually the contents will become liquid. Scrape the nitric acid out of the mixture.

How do you extract gold from electronics at home without chemicals
How do most people remove gold from circuit boards that do not contain protective chemicals? Get materials. Buy concentrated nitric acid. Use a large glass rod until the contents are uniform. Drain the nitric acid from the mixture.
What chemicals do I need to extract gold from electronics
Your countertops in a beautiful glass jar. In another container, mix two parts of hydrochloric acid and weak hydrogen peroxide (three percent concentrate). Simply pour this mixture over the printed circuit boards so that they are completely submerged in water.
