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.
Should you extract gold from electronics? 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.
Magann: A PC circuit board, where the gold is, weighs about a pound. If you had a ton of those boards, you should have 5 troy ounces of gold.
Computer CPU's (processors) have the most precious metal value by weight, followed by Memory (RAM) & Circuit Board Fingers / Connectors / Pins, then Circuit Boards (Motherboards), then cables / wires, with hard drives & whole computers being last.
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.
In brief, a Computer has around 0.310 gram of Gold which is worth around $20. Gold is present in Microprocessor, Wire tip coating and other components in a Computer.
There is no gold on the disk platters or any of the disk mechanism. Gold is present on most electronic circuit boards.
Gold is used in the manufacturing of SIM cards due to it being a very excellent conductor of electricity. Other than this, it is also very durable. However, each SIM card contains very little amount of gold, and you need thousands of SIM cards to be able to extract a few grams of gold.
Average mix 3.32 g per kg.
Some other sources estimate that your average computer contains about 1/5th of a gram, or about $12 worth, of gold in them. Laptops, on the other hand, typically contain about 1/10th of a gram of gold, or around $6 worth.
A television contains copper, quartz, iron, gold, platinum, and silver in its parts. List any other uses you know for these mineral resources.
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.
Removing Gold Using Fire
Use steel tongs to turn over the burning circuit boards. Get a metal bin or tray, and put the circuit boards into it. Break the boards into smaller pieces so they burn faster. Light the boards on fire.
The Ram 1500 is available from $85,950 to $265,000 for the 2023 range of models in Dual Cab body types.
It's estimated that the average desktop CPU contains around 1/5th of a gram of Gold or 200mg. Today's gold prices make the total amount of Gold in a desktop CPU worth about $12.
Motherboards and Circuit Boards
Motherboards – the biggest circuit boards inside both laptops and desktops – often contain the “mother lode” of gold in used computers. Their edges have gold contacts and connectors where wires slide on. You will also find thin layers of gold applied to motherboards' surfaces.
Gold in iPhones
A typical iPhone is estimated to house around 0.034g of gold, 0.34g of silver, 0.015g of palladium and less than one-thousandth of a gram of platinum. It also contains the less valuable but still significant aluminum (25g) and copper (around 15g).
There is only about 1/35th of a gram of gold in an average cell phone's interior. Not much, because gold is super malleable and gold is so soft and nontoxic, we can eat gold sheets and shavings.
Gold. Gold is used in mobile phone circuit boards because it is chemically stable and conducts electricity.
