How to reverse electroplate gold?
When reverse electroplating gold, items are placed into a one chemical electrolyte, or drain opener containing concentrated sulfuric acid, which is easily obtainable from local sources. To operate a common manual automobile battery charger is used. This process is specifically designed to recover gold-plating from gold-plated, gold-filled or rolled-gold jewelry, necklaces, rings, gold-plated computer pins, hardware, gold-plated flat-ware, gold-plated eyeglass frames, and virtually any gold-plated metallic object. This method does not allow for recycling of the electrolytic solution. The cost of the electrolyte for each session is approximately $8.00 per 1-quart batch so when you consider that if you run 3-pounds of gold-plated pins or jewelry per session you will recovery upwards of $400.00 worth of gold, making the cost of the electrolyte trivial.

Can you use gold toned gold on jewelry?
A word of warning; be extremely cautious when acquiring gold-plated jewelry. If the jewelry is marked "Gold Tone", "Toned Gold" or "Monet", do not use it. It is not gold but rather a plating process called "Zinc Clad". Running this material with the true gold-plated, rolled-gold, or gold-filled materials will cause recovery problems and will contaminate the final recovery product. If you are going to strip jewelry, I strongly suggest using a gold testing kit to insure proper recovery.
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 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 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.

Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities.
What is the power density of a plating action?
The power density (available energy) at the site (molecular) of the plating action is a direct result of the surface area of the electrode. The ‘size’ of the electrode affects the voltage and current per unit area on the surface. There will definitely be more plating (or stripping) action at a site with a higher voltage and current flow than there will be at a site with a low voltage and current flow.
How many atom pairs of atoms are in a 100 volt split?

What is the first step against confusion and obfuscation?
The first step against confusion & obfuscation is recognition that words must be used correctly and with consistent meanings. Voltage, current, power, energy, current density and so on all have established scientific meanings, which let us relate them to each other and advance the science via Ohm’s Law and Faraday’s Law, etc. — and it is absolutely relevant to immediately point out when someone misuses those terms in a fashion that can lead to erroneous conclusions.
What metals are used for copper foil?
A. All you need is a "passive" cathode. Stainless steel is probably adequate. Copper foil is routinely fabricated by electroplating copper onto a stainless steel belt and then separating them; the same idea should work for precious metals.
How long does it take to dissolve platinum?

What happens if you leave iridium in platinum?
The platinum will precipitate as a red mud. If you want to leave the iridium in the platinum, then wait for it to precipitate before recovering the platinum. Iridium will precipitate as a blue-black mud after the platinum precipitates. Platinum group metals will also show up on the stannous chloride test.
How to get platinum out of gold?
To insure high purity of the platinum, you will need to re-refine this material. Put this material in a fresh aqua regia bath. This time, however, heat the acid to simmering. Continue heating until all the platinum is dissolved (that may take 1-2 hours). When completely dissolved add 1 ounce of ammonium chloride for every ounce of dissolved platinum. The platinum will precipitate as a red mud. If you want to leave the iridium in the platinum, then wait for it to precipitate before recovering the platinum. Iridium will precipitate as a blue-black mud after the platinum precipitates. Platinum group metals will also show up on the stannous chloride test. Platinum turns red, palladium turns orange and iridium turn blue-black.
How many kt of gold is on a circuit board?
A. Hi Jared. The gold plating on circuit boards will usually be 24 kt, or very close, but the issue is that the plating is very very thin. On reasonably current computers it’s probably something like 20 millionths of an inch on the tabs — and half of that in other areas. Calculate how many square feet of gold plating it takes to get a worthwhile amount of gold.
How much does it cost to build a refinery?
Any operation which involves burning or chemical treatment should be left for a real refinery anyway. Proper refineries cost tens to hundreds of millions of dollars .

Is cyanide a dangerous poison?
This thread includes many entries by amateurs with no appreciation of the hazards of cyanide, and educating them that it is an extremely powerful and fast acting poison, both by ingestion and accidental acidification, is not fear-mongering but a reasonable attempt to instill healthy respect.
Can 10 amps be used for electroplating?
A. Hi Jared. Either will work equally well after a fashion, it just depends on the volume of material you are processing (a 10 Amp unit processes more material faster) — but neither will be great because they are designed to charge batteries, not as power supplies for electroplating. As Geoff warns, it’s really best to leave chemical and electrochemical processes to people who are trained in it because there are dangers at every step in the process.
