How do you dissolve gold in computer parts?
To get started, add the sea salt into a beaker, pour the vinegar in, and stir until the salt dissolves. Vinegar and salt form a powerful, but non-corrosive stripping solution needed to etch out the tiny gold particles on the computer parts.
What will bleach do to gold?
Both cause a chemical reaction that disintegrates the alloys in the jewelry over time. (Nearly all gold jewelry is alloyed, because pure gold is too soft on its own.) One study showed that when a 14K white gold ring was placed in common household bleach for 36 hours, the ring completely disintegrated!
Will bleach dissolve gold?
Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore. This was the first commercial method used for gold extraction.
Will hydrochloric acid and hydrogen peroxide dissolve gold?
Actually, gold metal dissolves in the presence of both a strong oxidant and a halide anion under highly acidic solutions. Moreover, a hot solution of hydrochloric acid mixed with a hydrogen peroxide (H^sub 2^O^sub 2^) also dissolves gold according to the chemical reaction (see Reaction 5).
How much gold is in a CPU pin?
For every 500 grams of gold plated pins on CPU's, the average refined yield is typically around 1 gram of pure gold.
What acid do you use to extract gold?
The most useful and important vehicle for dissolving gold is aqua regia, (royal water), composed of two parts of hydrochloric (muriatic) acid, and one part of nitric (aquafortis).
How do you melt gold flakes at home?
The most efficient way to melt gold at home is by using a propane torch. This method will melt gold in a matter of minutes. Place the gold inside a graphite crucible. Then, gradually direct the propane torch toward the gold.

How much gold is in a computer hard drive?
Some other sources estimate that your average computer contains about 1/5th of a gram, or about $12 worth, of gold in them. Laptops, on the other hand, typically contain about 1/10th of a gram of gold, or around $6 worth.
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.
SMB as a gold recovery chemicals
Many people ask me about SMB. I thought I start from this. Full form of SMB is Sodium metabisulfite. It is also known as sodium pyrosulfite. Its chemical formula is Na 2 S 2 O 5. Its color is white and in powder form. It is used for gold precipitation. There are many companies are manufacturing SMB but BASF company is best.
HF as a gold recovery chemicals
Full name of HF is hydrofluoric acid. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Its Other names are fluorhydric acid and Hydronium fluoride. It is most danger acid in the world. But in some method of gold recovery, it’s used. So if you are going to use it then be careful because it can harm you. Its price is high.

Borax is also known as sodium borate, sodium tetraborate or disodium tetraborate. Powdered borax is white, consisting of soft colorless crystals that dissolve easily in water. Its chemical formula is Na 2 B 4 O 7 ·10H 2 O. Borax is also used in flux. It helps in gold smelting. Its melting point is 743 °C.
How to make gold from scraps?
Step 1: Extracting Gold From Scraps. Collect any gold-containing metal scraps to which you have access, including jewelry, computer processors, old telephone wiring or gold tooth crowns. Keep in mind that outdated electronics are likelier to produce parts with a high enough level of gold to make the procedure worthwhile.
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 make a clay bowl with gold?
Heat your clay bowl, don’t worry if the bowl cracks or splits , add borax to the hot bowl, when the borax melts add the gold flakes and more borax then heat until you get a nice bead of gold, let it cool and weigh to see how much you lost. Ask Question.
What is the melting point of 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.

The mixture of vinegar (dilute acetic acid) and peroxide will leave gold untouched. The only chemical mixture that dissolves gold is aqua regia, a mixture of concentrated nitric and hydrochloric acids.
What is used to precipitate Au?
From a non-colloidal solution use sodium sulfide or zinc and electrolytic to precipitate Au.
Can you leach gold from circuitry?
Not really, you would need stronger acids to leach the gold from the circuitry. My recommendation would be that you can remove all the gold bearing components and place the content into a specialized crusher, that costs money. Plus, you woud have to pretreat the used acids and dispose of them LEGALLY. Then the leaching should be done with STRONG acids, NOT IN YOUR HOME because it can/will emit noxious/toxic gases that you would have to be protected from with eye protection, special clothing and perhaps a breathing apparatus. I really don’t know what reactions will occur until you have recoverable gold. You must also know the chemistries involved in each and every reaction that can recover, separately, gold, platinum, palladium and silver. This is a metallurgist’s question because this process MUST be conducted carefully.
Can you recover gold from computer scrap?
Acetic acid / vinegar is a weak acid. So you are not looking at any serious set of instructions to recover gold from computer scrap. You need to use strong acids such as concentrated hydrochloric acid. You will also need to invest in a proper respirator to avoid breathing in metallic fumes released when the acids are added.

What is mercury used for?
MERCURY. Mercury compounds are used to coat metals to prevent rust or inhibit foliage growth (marine paints). Under the intense heat of the arc or gas flame, mercury vapors will be produced. Exposure to these vapors may produce stomach pain, diarrhea, kidney damage, or respiratory failure.
What happens if you inhale zinc oxide?
Inhalation of zinc oxide fumes can occur when welding or cutting on zinc-coated metals. Exposure to these fumes is known to cause metal fume fever. Symptoms of metal fume fever are very similar to those of common influenza. They include fever (rarely exceeding 102o F), chills, nausea, dryness of the throat, cough, fatigue, and general weakness and aching of the head and body. The victim may sweat profusely for a few hours, after which the body temperature begins to return to normal. The symptoms of metal fume fever have rarely, if ever, lasted beyond 24 hours. The subject can then appear to be more susceptible to the onset of this condition on Mondays or on weekdays following a holiday than they are on other days.
