If appliances are used to heat things up (stoves, coffee makers) or cool things down (refrigerators, air conditioners), they contain thermocouples of some kind. Thermocouples can contain platinum, palladium, molybdenum, nickel, rhenium, rhodium, tungsten and even small quantities of gold. What are thermocouples?
Among all home devices, computers and televisions typically contain the most gold. Gold is also found in the circuit boards of earlier generations of cameras, radios, and media players. Traces of gold can be found in other electronics like game consoles, tablets, and phones.
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.
The circuit boards used for microwave component assembly also exploit gold for similar reasons. The substrate material in this case is a highly polished alumina tile.
Rhodium is used for several different things, such as automobiles, jewelry, searchlights, electronics and mirrors.
share. Podium's re-assaying of historical 3E platinum group metal (PGM) intercepts just confirmed Parks Reef is home to a most significant amount of rhodium – the world's rarest and most valuable metal.
Palladium is used in catalytic converters for automobiles, in fuel cells to generate power, in jewelry, dental fillings, and electronic components. Catalytic converters convert the toxic gases from automobiles into less harmful substances.
Over the years, lots of high-quality pens and pencils have been made of platinum. They include fountain pens, ballpoint pens, and mechanical pencils. Remember that platinum and silver are both white metals that can be difficult to tell apart by eye, but that platinum is more valuable.
So, on average, a Computer along with its accessories will have 0.310 grams of Gold. On specific high performance processors/ computers like Intel 386 and 486, Pentum 4 CPU, AMD Ryzen CPUs, Intel 80286 microprocessor have higher Gold content. The total amount of Gold from a single computer can go upto 0.500 grams.
Thermocouples and thermocouple wire are used in air conditioners to monitor and control temperatures remotely. They can contain palladium, platinum, rhodium, gold, and tungsten alloys.
Despite these challenges, the extraction of gold from electronics can be worth it for individuals looking to recover valuable metals and reduce e-waste. Additionally, gold prices are constantly increasing, making it an attractive investment for those looking to extract gold from electronics.
Strip out the boards
In another container, mix two parts hydrochloric acid and one part weak hydrogen peroxide (a concentration of three per cent). Pour this mixture over the circuit boards so they are completely submerged. Wait for a week, giving the vessel a stir every day with a glass or plastic rod.
Rhodium, iridium and ruthenium are perhaps the rarest, roughly 1/5 as common as platinum.
How much gold is in a computer hard drive? It is possible to find gold plating in small traces, not only in hard drives, RAM memory sticks, but in many other components of desktop or laptop computers. The exact amount can vary around 0.3 gram of gold worth around $20.

According to the International Platinum Group Metals Association, in the electronics sector, most palladium is used for multi-layer ceramic (chip) capacitors (MLCC). MLCCs store energy in electronic devices such as broadcasting equipment, mobile telephones, computers, electronic lighting and high voltage circuits.
Are Spark Plugs Worth Anything in Scrap? Well, spark plugs may be worth something in scrap. You can use your old spark plugs to earn some extra bucks from the scrapyards. However, you will need a large amount because, frankly, one or two spark plugs aren't worth anything.
Palladium was present in most food groups above the LOD of 0.0003 mg/kg with the highest concentrations found in nuts (0.003mg/kg), bread, offal, and fish groups (all 0.002mg/kg).
You can find palladium scrap in many different items. A couple places to look include: Palladium alloys used for manufacturing: Look out for palladium sponges, palladium flakes, palladium sputter and sputtering targets. Palladium jewelry items: This can include rings, chains, bracelets, jewelry scrap.
In terms of abundance in the Earth's crust, the rarest metals are: gold, platinum, osmium, iridium, palladium, ruthenium, rhodium, tellurium and rhenium.
Jewelry makers are especially keen on palladium because it does not tarnish like other metals such as silver or gold. In recent years, however, the price of palladium has surged due to increased demand from the automotive and. electronics industries. Palladium is becoming one of the most expensive metals on earth.
