How much gold is in your computer?

Electronic devices contain rare earth elements such as neodymium and europium, along with precious metals including gold and silver.

Gold is widely used in computer hardware components such as printed circuit boards, CPUs, and RAM, according to tech site BGR. Its resistance to tarnishing ensures long-term reliability, making it suitable for connectors, switches, bonding wires, and circuits where consistent electrical flow is essential. Gold plating is also applied to improve corrosion resistance and extend the lifespan of components.

However, the amount of gold in each device remains minimal. According to U.S.-based precious metals dealer SD Bullion, a desktop computer contains about 0.2 grams of gold, while a laptop holds roughly 0.1 grams.

Beyond computers, many household appliances, including refrigerators, washing machines, televisions, and even cars, contain printed circuit boards that use small amounts of gold. Smartphones contain small amounts of gold, but experts say dozens of phones are needed to produce just one gram.

However, extracting gold from electronic waste is hazardous. The process often involves strong acids such as hydrochloric and nitric acid, which can cause severe burns and release toxic fumes. Other methods, including electrolysis and controlled incineration, require specialized equipment and are not suitable for unregulated environments, according to tech site SlashGear.

Experts recommend sending old electronics to certified recycling facilities, where trained technicians can safely and efficiently recover valuable metals such as gold, silver, and palladium while minimizing environmental risks.
