HOW TO EXTRACT GOLD FROM ELECTRONICS WITHOUT CHEMICALS. When using the flammable, hardly breathable chemicals required by nothing less than a science lab to experiment with a small fortune, it can only result in a sloppy mess and some singed fingers However, there is one way to remove the gold from household electronics such as circuit boards,
Feb 28, 20140183;32;Great Video on how to Depopulate a Gold plated board to get it ready for the Precious Metal Recovery Process. This is Safe and involves no Chemicals
On electronics that use gold for shielding (such as RF shielding) the gold can be very thin and instead of coming off in foils will separate into finely divided particles and will get lost in trash. Another cause for missing gold recovered this way is bad work habits.
Jan 24, 20180183;32;How to Refine Gold. You may want to make some extra money by refining your own gold at home, or you may be a jeweler who wants to refine gold in house. There are multiple ways to refine gold on a small scale as long as you take appropriate
Gold Recovery Correctly I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold recovery such as quot;Cupellationquot;*. These processes are DANGEROUS and put the user at t
Mix a refining solution. Although you have recovered the gold from the electronics scrap, it may not be pure gold. It may be 12k or 18k gold, so now we will refine it to be pure 24k fine gold. Take a second beaker and pour it half full of Aqua Regina. Be very careful. Aqua
Stripping the Gold. The acid can be diluted a bit with water if needed, but do not exceed 21 V/V (acid/water) ratio. Small amount of Copper Chloride solution is then added to the solution. The bubbling action from the pump will keep the solution both aerated (oxygenated) and agitated.. The Copper ions
May 15, 20130183;32;Clean, cheap method for extracting gold discovered by accident. Researchers stumble upon a method that could replace toxic cyanide with plain old cornstarch. Photo optimarc/Shutterstock. Until the 17th century, alchemists tried to transform base materials into gold.
Mar 07, 20140183;32;How to extract gold from electronics. Make sure you have suitable protective equipment (goggles, gloves and overalls to protect your clothes) and a suitable and well ventilated (or outdoor) work space.

I also use SMB made by this German company. Its result is hundred percent and clear. 1 kg jar can be expensive but if you purchase is 25 kg bag then it will be very cheap.
How to recover gold from computer parts, learn about how to recover gold from computer parts, e waste, chips, CPU, x ray films, photographic waste, aqua regia, cyanide solution, circuit boards and RAMS. Recovery methods extract or recycle of precious metal like Palladium, Silver and Gold.
A green process for extracting gold. The problem with gold is that it's one of the least reactive chemical elements on the planet, which makes it difficult to dissolve. Thus current industry standard methods to remove it from scrap electronics rely on either highly toxic cyanide solutions that are non recyclable,
hydrometallurgical method for extracting gold from ceramic and composite central processing units (CPUs) of computer circuit boards without special solvents. Materials and methods This research utilized composite (15 samples) and ceramic (15 samples) CPUs of computer circuit boards (Figure 1). The study process consisted of six steps (Figure 2).
3. 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.
The gold flakes will remain on the filter. Fill the plastic tray with water to half of its depth, place the remaining circuit board scrap in it and rinse. Pour this water through the filter to extract any remaining gold flakes. Flush water over the gold flakes to wash them. Pour the methanol through the filter to wash the gold
