Extracting gold from SIM cards is possible through a chemical process using strong acids and reducing agents, but it is a complex, risky, and generally not practical for an individual due to the extremely small amount of gold present in each card. The process involves hazardous chemicals and requires strict safety precautions.
Things You Should Know
Use scissors to cut just above the line. Do not cut into the gold or metal part of the SIM card.
In addition to identification and authentication, the SIM card can also store the subscriber's contacts, messages, calls, location information, and other subscriber-specific data.
Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost.
According to my knowledge, you can get 15.5 grams of gold from 1 kilogram of rams. This is because the gold content in rams is about 0.155%, which means that there is 15.5 milligrams of gold in every gram of rams. So, if you have 1 kilogram of rams, which is equal to 1000 grams, you will have 15.5 grams of gold.
Vinegar is very destructive, so when you apply the vinegar to a fake piece of gold, the vinegar will cause the jewelry to tarnish. Gold is a non-reactive metal, so real pieces of gold will not react to vinegar.
Because of SIM card technology, you are able to keep your phone number from device to device, or even carrier to carrier, while easily transferring hundreds of text messages and other data simply by inserting your current SIM into your new device.
The amount of gold in SIM cards is very small, usually measured in milligrams or even micrograms. For example, a typical SIM card may contain around 8 milligrams of gold, which is equivalent to 0.00028 ounces. This means that you would need around 3,571 SIM cards to get one ounce of gold.
Among consumer electronics, computer components are the richest in gold. Circuit boards, especially motherboards, feature gold in their connectors and pins. CPUs are particularly valuable, with older processors containing 0.2 to 0.5 grams of gold each.
Remotes contain only a few cents' worth of gold that can be found on the edges of the printed circuit boards they contain. But if you do the math, you'll see that a few hundred remotes can be worth more money than you suspect.
Some other sources estimate that your average computer contains about 1/5th of a gram, or about $12 worth, of gold in them. On the other hand, laptops typically contain about 1/10th of a gram of gold, or around $6 worth. However, the actual value will depend entirely on the type of e-waste you are looking at.
Gold in a Cell Phone
Gold is mostly found within a smartphone's circuit board, also known as the motherboard, which acts as the brain of the device. It facilitates communication between various components like the microprocessor, memory, and display.
Here are 7 ways to check if someone is using your SIM card:
Yes. 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.
Your phone number is not permanently linked to your SIM card. Number portability allows you to switch operators or SIM cards while keeping your number. You can change your number without replacing your SIM card by contacting your operator.
Your photos, videos, contacts, apps, ringtones… everything else that isn't your phone number, will still be on your phone after you remove the SIM card. Obviously, you won't be able to call or text those contacts without a phone number, and some apps may not work without a network connection.
A SIM-eject tool. It's a thin metal tool that probably came with your phone when you first got it. If you have one from a previous model, that should work too. If you don't have a SIM-eject tool, you can use a small paperclip.
Iirc, chlorine and chloride can attack gold alloys. Cyanide will attack gold. Strong acids will attack the rhodium finish, sulfuric in particular. It may be worth considering purchasing a sterling silver band.
Carefully place the gold piece into a bowl or cup of water. Genuine gold will settle to the base of the cup. If it is not real, it will rise to the top of the cup or remain motionless in the middle. Because of its high density, gold will quickly settle to the bottom of any water container.
It should also never have any discolorations. As gold does not react to vinegar, you can use white vinegar to test your ring and see if it changes color. After leaving the jewelry in vinegar for around 10 minutes, a 24k ring will remain the same, while a fake gold ring will have black or discolored markings.
