Yes, printers do contain small amounts of gold, primarily as plating on circuit board connectors, pins, and sometimes on ribbon wires, used for reliable conductivity because gold doesn't tarnish, making them valuable for e-waste recycling, though not in the ink itself. These precious metals are found in the internal electronics, especially on high-grade circuit boards, making printers a source for recovering gold and other valuable metals like copper, silver, and palladium.
There are these solenoid coils and some optical encoders plus the toner and the drum kit that can be salvaged as well as the laser and prism assembly. So if you have old printers lying around at home that you can no longer use try to see what useful parts you can salvage out of them.
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.
Gold has maintained a high financial value, reaching over $2,000 an ounce. At these prices, a skilled recycler extracting gold from electronics can expect to receive over $10,000 worth of gold from just one ton of computer circuit boards.
Water-based JG-125 is a highly-conductive gold nanoparticle ink developed for inkjet printing with excellent adhesion and water resistance.
The grade of electronic waste is generally between 800 and 1500 g/t, and 0.8-1.5 g of gold can be extracted per kg of waste.
Other sources estimate that the average computer contains 1/5th gram of gold, which is worth about $12. Laptops, on the other hand contain around 1/10th gram or $6 in gold. The actual value of the e-waste will vary depending on its type.
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.
Gold is also found in other consumer electronics, such as digital cameras, DVD players, and gaming consoles. These devices contain between 0.01 and 0.05 ounces of gold.
The dirty gold jewelry on your nightstand to outdated electronics in your attic contain precious scrap gold and silver. The most common household items, including watches, circuit boards, and dental fillings, have minute but worthwhile amounts of precious metal that accumulate over the years.
Pause – before recycling your old printer, here's what else you could do with it.
Similarly, older fax machines often contain circuit boards rich in precious metals, such as gold and silver, which can be extracted and reused.
Are Old Printers Worth Keeping? If a printer is over seven years old, it's probably costing you more than it's worth in terms of print supplies, repair, and electricity.
An adult human body contains approximately 5 liters of blood, which contains different metals such as iron, chromium, and zinc, as well as about 0.2 milligrams of gold [1]!
Quick Take: 10 Years of Investing in Gold
Ten years ago, the price of gold had an average closing price of $1,159 per ounce. Today, it's worth about $4,200 per ounce — a 262% increase in value. So, if you had invested $1,000 in gold a decade ago, it would be worth approximately $3,620 today.
Gold is an essential material in electronics and plays a vital role in smartphone manufacturing, though less than 0.007 to 0.034 grams of gold is in a cell phone. Despite the small content, gold's exceptional properties make it an irreplaceable component in modern mobile phones.
Gold Purity and Karats
Most gold scrap comes from jewellery made with lower karats, such as 10k, 14k, or 18k. The higher the karat, the more pure gold it contains, and the higher the price you'll get. For example, 14k gold contains roughly 58.5% pure gold, while 18k gold contains 75%.
Gold in computers is primarily found in the Central Processing Unit (CPU) and memory chips. Gold is utilized in these parts due to its exceptional ability to conduct electricity. Besides the CPU, gold is also used in various connectors, such as USB ports and specific cables and wires.
Could your computer still be worth something that way? Actually, yes! This depends entirely on market factors, and the prices can fluctuate almost daily, but in some cases, your computer could still be worth money even if it is just being entirely scrapped for recycling, and of course, Sadoff can handle that too.
