Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Its chemical properties make it useful for the manufacture of computers parts, electronics, jewelry and dental work. Some people find it profitable to attempt to extract the gold
Computers and other electronic devices contain gold and other precious metals in their circuit boards. As consumers upgrade their electronic gadgets, the precious metals remain trapped in piles of waste. Theres about grams ( ounces) of gold in a typical mobile phone handset. Recovery of this gold
How to Extract Precious Metals From Computers By Norm Dickinson There is gold to be found in old scrap computers and electronics. Recovery of precious metals from computer scrap is a highly specialized process that involves disassembly of the computer, separation of preciousmetalbearing components and a series of chemical processes to recover
Mar 07, 2014#0183;#32;Use a magnet to separate all goldplated steel parts, as you need a different process to extract it. quot;Older electronics have more gold in them,quot; says Murchison. quot;The best thing I extracted gold
The gold residue can be purified to extract percent 24Carat gold. Ordinary Burning. This isnt exactly the way to recover gold. However, you can sell the char for a lot of money since it contains gold. Remove all parts of a computer that contain gold and burn them in a large metal barrel.
Gold is a very nonreactive metal, which forces companies to use chemicals such as sodium cyanide to dissolve and extract gold. However, sodium cyanide is both environmentally damaging and expensive, making it unsuitable for stripping small amounts of gold from electronics.
Recycling gold from jewelry or electronic scrapsthink computer chips and circuits lined with thin layers of goldis not without issue either. the gold extraction is done under very mild

Mar 31, 2020#0183;#32;What Electronics Have the Most Gold in Them? There is no simple answer to the question of which electronics have the most gold in them, a representative from Specialty Metals, Smelters amp; Refiners in Connecticut told us. We consulted with escrap recyclers and scrap gold refiners, as well as scrap retrieval videos and scrap forums, to create the following list of electronics that have gold
2 #0183;#32;The extraction of gold from old electronic components and electronic boards is not a new process. To be precise, two distinct chemical methods are used for extracting gold from old electronics. The first method uses one of the most powerful acids in the world, aqua regia.
Nov 23, 2013#0183;#32;3. Collect any goldcontaining 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.
