Refining gold plating takes two steps. The first step involves reverse electrolysis to remove the gold from the plated item. Electrolysis is an electrical process where the negatively charged ions from the gold adhere themselves to the positively charged ions of another metal or material. To reverse the process, you will want the positively charge the gold plating so that it will be attracted to the negatively charged ions in another material -- often silver but for this process it will be stainless steel. To allow the transference, it must occur in an electrolyte solution.

1.Collect all the gold plated material you want to refine to 24 karat gold. This can include the circuit boards of old 386 or 486 computers, old analog cell phones, stereo cables, jewelry and any other materials that have been gold plated. Gold's high electrical conductivity makes it attractive to sparing use at critical circuit junctions but its price limits its use.

2.Prepare an electrolyte solution in a glass beaker consisting of 70 percent sodium cyanide (NaCN), 15 percent sodium hydroxide (NaOH) and 15 percent sodium-meta nitro benzene sulphonate. This will serve as a chemical bath conductor to better facilitate the free-flow of ions from the gold-plated material. Use a glass wand to stir the mixture thoroughly.

3.Prepare your electrical source. Either a 9 volt of 12 volt battery is satisfactory. Clean and attach a small alligator clip on one end of each of two 9-inch wires. Connect the opposite end of one wire to the positive end of the battery and the end of the other wire to the negative end of the battery. Attach the alligator clamp from the positive wire to the collected scrap gold and gently lower the gold scrap into the beaker containing the electrolyte solution. Connect the alligator clamp attached to the negative end of the battery to the steel post and slowly introduce the steel post into the electrolyte solution, letting it come to rest at the bottom of the beaker. Basically, you're creating a circuit that will flow through the electrolyte solution transferring the positively charged gold ions to the negatively charged steel anadode.

4.Wait for the low volt charge to do its work. It will take a little while to positively charge the gold-plated materials and generate current sufficient enough to carry it to the ions to the negatively charged steel anode. The amount of removed gold plating adhering to the anode can be measured in microns (basically because you're using small amounts of plating and the low electric current). And will take time to accumulate on the anadode. Over a period of time the gold adhering to the anode will thicken and can be scraped off when the process is complete.

5.Repeat this process with all the gold plated material you wish to render. Along with the gold, however, came impurities rendering the gold somewhere between 12 karat and 18 Karat gold. To refine the gold further and remove the impurities requires another step to make it 99.99 percent pure or 24 karat gold.

6.Fill a separate glass beaker half-way with aqua regia, which is a mixture of nitrohydrochloric acid hydrochloric acid. Gently introduce the gold into the solution and fill the beaker with sodium meta bisulphite and stir gently with a glass wand. No splashing. The impurities will dissolve and the 24K gold will settle to the bottom of the beaker. Drain the solution as much as possible without splashing or pouring off the refined gold and allow the gold to dry. Wash the gold thoroughly with water and you've reversed the electroplating process and have the pure gold that was used from the start.

Dissolving Materials
Use chemicals to dissolve the materials underneath the gold of circuit boards. CBX and StripFree products work well but do have drawbacks. CBX is a powder that is good to use in areas where not a lot of other metal types are close. It will be used too quickly otherwise, reducing its cost effectiveness. StripFree should be used when an item is stainless steel based, as the solution uses an electric current to separate the gold from the board. It does require access to a car battery to work, however.

Acid Baths
Use an acid bath. While the chemicals above dissolve the materials beneath gold, acid baths are designed to dissolve the gold itself. Aqua Regia is an acid used to submerge the circuit boards. Once the boards are removed from the acid, the remaining brown, murky water will contain dissolved particles of gold. This process uses highly corrosive substances that have been made safer by the inclusion of SubZero as a replacement for nitric acid in traditional Aqua Regia. Protective clothing and precautions should still be taken when using an acid bath process.

Precipitant
Use a precipitant. Added to water, the precipitant will form a solution that will separate the gold from the acid. The separated gold, once the acid has been discarded, will resemble brown mud. At this point, no further chemicals or solutions will be needed to retrieve the gold. Washing the mud in aqua ammonia and tap water will result in a powder. The powder will then need to be melted to return the gold to its pure state.

Gold plating is generally found on circuit boards and fingers inside of computers. There are many ways to recover gold plating but one of the quickest and relatively safest ways is to soak your gold plated item in CBX circuit board stripping powder solution.

1.Put on protective eye goggles and waterproof gloves.

2.Pour out the contents of one jar of CBX circuit board stripping powder into a ceramic bowl or container. You can purchase the powder from shorinternational.com.

3.Add 1 gallon of water to the container and mix with a wood spoon.

4.Add your gold-plated material to the bowl and allow to soak for 6 to 8 hours.

5.Remove the gold-plated material from the solution and set aside. Make sure you are wearing waterproof gloves when you do this.

6.Set a coffee filter into another ceramic bowl or container and pour the liquid into the coffee filter. Lift up the filter as the bowl starts to fill up with liquid. The gold can be found in the filter.

Tungsten alloy swaging rod consists of W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe. Tungsten alloy swaging rod is made of tungsten alloy rod. After being swaged, the ultimate stensile strength can reach 1200 MPa or even 1400MPa. Tungsten alloy swaging rod is widely used in military industries. Massive ordnance penetrator used tungsten alloy swaging rod as its warhead.

Massive Ordnance Penetrator (MOP)is a U.S. Air Force, precision-guided, 30,000-pound (13,608 kg) "bunker buster" bomb. This is substantially larger than the deepest penetrating bunker busters previously available, the 5,000-pound (2,268 kg) GBU-28 and GBU-37.

With tungsten alloy swaging rod, massive ordnance penetrator can penetrate deeper and destroy underground bunker.
