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.
There are 0.034 grams of gold in each cell phone, according to the U.S. Geological Survey. That's the equivalent of 0.001 troy ounces, worth about $1.82 at today's prices.
Magann: In very rough numbers, there are 10 troy ounces of gold (or about three-fifths of a pound) per ton of smartphones. Ten thousand phones weigh one ton.
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).
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.
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.
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.

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. Extracting gold for several computers together is cost productive.
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.
A television contains copper, quartz, iron, gold, platinum, and silver in its parts.
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.
While extracting gold from electronics is not without its challenges, it can be worth it for individuals looking to recover valuable metals and reduce e-waste. However, following safety precautions and using personal protective equipment when handling hazardous chemicals is essential.
Copper makes up the connective wires. A study out of the Harare Institute of Technology also listed that printed circuit boards contain, “about 20 wt% copper, 0.04 wt% gold, 0.15 wt% silver, and 0.01 wt% palladium,” with wt% representing percentage by weight.
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 short, yes, they work. Many Android apps come equipped with a magnetometer. It's mostly used for stuff like GPS or part of the compass functionality. However, it is also capable of detecting metal.
However, it is important to note that you must still declare the items to Customs and Border Protection (CBP) Officers. If you are travelling with more than $10,000 worth of gold coins (or silver coins), you will need to fill in a FinCEN 105 declaration form.
Gold-bearing circuit boards are increasingly used in appliances like microwaves, air conditioners, refrigerators, and kitchen stoves. A good rule of thumb is: The more technological features that an appliance has, the more likely it is to contain small amounts of gold.
It is estimated that the amount is in the same order of magnitude as the quantity in electronic scrap. However, the amounts of gold are very little in the single-car. Frankly, it is quite difficult to extract the material that is spread out in small quantities (usually one to two grams of gold per vehicle).
Look for flea markets or shops with costume jewelry.
This is the easiest way to collect scrap gold. Google flea markets and thrift shops near you. It's best to look for larger flea markets with lots of vendors, as these events will concentrate the most potential gold in one spot.
