Step 1: Prepare the computer parts
The best parts to use in this experiment are printed circuit boards, motherboards, central processing units, random access memory chips, drives, and other internal modems.
Step 2: Clean and dry the parts
Clean the computer parts under a tap of running water to remove any dust or residual plastic—air-dry the components before beginning the process of extracting gold.
Step 3: Prepare the stripping solution
In this experiment, we will use a mixture of sea salt, vinegar, and hydrogen peroxide. Others elsewhere might recommend using toilet bowl cleaner and hydrogen peroxide to do the same job.
Step 4: Connect the apparatus to an air pump
Take another glass beaker and insert a tube connected to an air pump. This setup will help to circulate oxygen and remove unwanted gas from the stripping solution.
Step 5: Mix the stripping solution with the e-waste
After placing the e-waste into the beaker, add the stripping solution of vinegar and salt into the beaker. Do this slowly, ensuring that all the computer parts are fully submerged in the solution.
Step 6: Keep an eye on the apparatus
After 24 hours, check on your experiment and stir the solution. You might notice that the solution has turned light blue, but more importantly, you will start to see tiny gold foils floating around.
Step 7: Strain out the gold foil
It is now time to separate the gold foil from the solution. If you soak the electronic parts for a couple of days, you will notice that the salt, vinegar, and peroxide solution gets thicker. Don’t worry; you will still be able to fish out the tiny strips of gold extracted from the computer parts.

How to recover gold from a gold flakes?
There are basically two methods of melting gold flakes and dust to recover gold available to the average person, the mercury method called Gold-Mercury Amalgam with its obviously toxic by-products and the Borax Method.#N#I do not recommend the mercury method it works but it is extremely toxic for generations.#N#The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery increases.

How to get gold flakes out of a circuit board?
A week has passed and it is time to collect your gold flakes and dust from your cleaned fingers and circuit boards, after a week the acid darkens and with a stir the flakes of gold can be seen floating around in the pot.#N#Pouring the acid into a coffee filter the acid passes through the filter leaving the gold behind, save the acid do not dump it down the drain.#N#Next dump the remaining fingers and circuit boards into a deep plastic tray and add water, sort out the cleaned of gold parts, put the cleaned parts in the waist and save the un-cleaned parts for re-dipping.#N#After you have sorted the circuit board parts pour the water off through the coffee filter and flush with methyl hydrate to clean. Since the methyl hydrate is 99.9% methyl alcohol it cleans and dries the gold flakes better and faster than water, water will cling to the gold flakes and give you a false weight.

How to recover gold from a solution?
Recovering your gold in solution is one of the Coolest steps.#N#Whats needed, a plastic spoon, and the sodium Bisulfate or Stumpout.#N#Simply add very small amounts of stumpout, Your Mixture should start to look like the pictures I have provided. This is caused by the SO2 Gas which acts to chemically displace the gold in solution.#N#When the reaction has finished you will have driven out a majority of the chlorine, and replaced it with Sulfur. Any gold which was trapped in the solution has now be come a brown precipitate at the bottom of your beaker.#N#Retest with Stannous chloride, if your reaction still turns purple you need to add more stumpout.#N#It will take appox 10 hours for the gold to competely settle, the solution should be clear at this point.
