Hello, I am interested in methods of gold recovery from computer and electronic parts. I have quite a lot of this scrap, but due to the limited space I would like to throw away the rubbish. Thanks in advance for any information.
Sort it carefully first, then you will have more space in the basement. The greatest amount of gold is in computer processors - the old ones, pentiums, 486 and even older ones, as well as in boards - edge connectors of "Odra" computers. "Riad" etc. In total, people recover gold even from transistors and goldpins, after collecting several dozen kg. this commodity is sent to a specialist gold recovery company (a friend of mine sent to the Czech Republic). I do not recommend recovery by home methods, gold as a precious metal dissolves only in "royal water", a very caustic compound and in cyanide and mercury compounds (amalgams), both substances are extremely toxic and cannot be used in the house. In addition, you will not buy most of these substances - as they are toxic, they are not available for sale, or they are on the list of precursors (nitric acid), i.e. as above.
This is how I suspected that in processors, and I like to collect these processors, they do not take up much of a look. I did not know that this process was so poisonous and dangerous. The question is how many kilograms of processors would be needed to get it 1 gram / kilogram of gold is it profitable and feasible?
I also watched this show It is profitable and feasible, but for companies that process tons of it, and not for someone who has snickers cartons of processors.
Besides, it takes a lot of effort to get gold, and gold is not just a jeweler, but an industrial one (gold salt or something ... I'm not a chemist, so I won't explain what it is, but there was something about it)
You express opinions as if you were doing it. I am interested in the opinion of a practitioner. "Snikers carton" is not a tangible quantity. It is known that I will not go to the Czech Republic with 20 Pentium procks expecting a kilogram gold bar.

In the 1980s, a disabled person used to drive on the stock exchanges in my city and bought "golden Russian cases" from watches. They were probably gold-plated. If 20 years ago there were recovery technologies, maybe it's not worse now?

Gold from steel surfaces is easily eaten with cyanides. Copper and silver dissolve in cyanides, which complicates the recovery process. to remove gold from copper surfaces, I recommend solutions with iodine or sublimation of gold iodide with iodine vapors
The discussion centers on methods for gold recovery from electronic components, particularly computer processors and circuit boards. Participants caution against home recovery methods due to the toxic nature of chemicals like cyanide and royal water. They highlight that older processors, such as Pentium and 486 models, contain significant amounts of gold, with estimates provided for gold content in various CPU models. The feasibility of recovery is debated, with suggestions that it is more practical for companies processing large quantities rather than individuals with small amounts of scrap. Additionally, some users inquire about professional recovery services, particularly in the Czech Republic, and the potential for gold in other electronic components is discussed.
