Use Nitric Acid If you have a circuit board with gold plating, you can remove the gold using nitric acid. The acid will dissolve the metal and leave the non-metallic components of the circuit board intact. Be sure to wear goggles and gloves when working with nitric acid, as it can cause chemical burns.
Despite these challenges, the extraction of gold from electronics can be worth it for individuals looking to recover valuable metals and reduce e-waste. Additionally, gold prices are constantly increasing, making it an attractive investment for those looking to extract gold from electronics.
However, extracting gold from electronics is difficult, and the amount of recovered gold from a single device is very low. Gold is a very non-reactive metal, which forces companies to use chemicals such as sodium cyanide to dissolve and extract gold.
In fact, computer parts contain the most gold. It is possible to recover gold from computer boards; it is also possible to extract gold from motherboards, integrated circuits, contacts, pins and printed circuit boards.
We believe it conservative to say with today's gold price, over $10 of gold gets layered in an average computer. In other words, 1/5th of a gram of gold can get pulled or withdrawn from an average computer's interior.
Desktop Computer
It sounds simple enough: just take out some of the shiny components, ship them to authorized gold refiners, and wait to get paid. The largest circuit board in both laptops and desktops, the motherboard, is the part where the most gold can be found.
Pour nitric acid into the glass container over the circuit boards. Stir the mixture with the glass or metal rod until the contents become a uniform fluid. Once the gold has separated from the plates — it may take some time — strain the nitric acid from the mix using the filter. Take out the pieces that aren't melted.
The processors and connectors in computers, tablets, and smartphones use gold. You can also find gold in televisions, gaming consoles, printers, or essentially anything electronic.
The 24K gold is used to make coins, bars and is also used in electronics and medical devices. The 22 Karat gold is mostly used in making jewellery. In 22K gold, 22 parts of the metal are gold and rest two comprises of metals like silver, zinc, nickel, and other alloys. It is also known as 91.67 per cent pure gold.
Recovering gold from junk electronics, also called urban mining, may be profitable if you can amass large volumes of electronic waste (e-waste), particularly computer parts. It may not be worth the ordeal to extract gold from a small pile of junk hardware.
If it's real gold it will not stick to the magnet. (Fun fact: Real gold is not magnetic.) Fake gold, on the other hand, will stick to the magnet. If that necklace leaps to the magnet, your significant other has some explaining to do.
Not necessarily. While it's true that there are precious metals in electronics, the economic value has not proved to be what many might have expected when e-waste recycling was still fairly new.
Circuits in modern CPUs and Laptops weigh around 100 gm so you can expect to extract 0.150 grams of Gold. Additionally, the wires and connector pins have gold which will amount to another 0.070 gram and another 0.090 grams for gold plated contacts.
Something) I'm using simple math its about 37.00 bucks of gold newer computers are about a 1/3 of a gram that's the ram, board fingers, processors. And hard drives, this came out to about 10-12 bucks per computer.
TVs usually contain a very small amount of gold that might amount to about $1.00 or less in value. It can be quite a lot of work to get to the gold inside your TV as well.
The circuit boards used for microwave component assembly also exploit gold for similar reasons. The substrate material in this case is a highly polished alumina tile.
The main component of a SIM card is the electronic chip made from Silicon with some added impurities such as phosphorous . It is plated with metals such as Gold to form outer layer which makes contact with your mobile phone. This chip is housed inside a shell made from plastic. 1,000 SIM Card Approx Contains 1 gm Gold.
Strip out the boards
In another container, mix two parts hydrochloric acid and one part weak hydrogen peroxide (a concentration of three per cent). Pour this mixture over the circuit boards so they are completely submerged. Wait for a week, giving the vessel a stir every day with a glass or plastic rod.
Goldvish Le Million ($1.3 Million)
This phone at one time was a Guinness Record holder for world's most expensive phone. The body is made out of 18-karat white gold and has been studded with 120 carats of diamonds.
