Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first. The process involves a number of steps which have to be carried out carefully in order to get the desired results. There are some instruments and acids involved in the process. Necessary precautions must be taken before starting the …
That's a lot of chemicals. BBC science show Bang Goes the Theory goes all out to extract gold from old circuit boards.
If you have access to a large amount of e-waste, you may literally be sitting on a gold mine. There is gold that can be recovered from discarded computer circuit boards--but in such small amounts that the time-consuming and dangerous process required to remove gold from computer circuits is only worth your while if you have at …
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. Since billions of electronic products worldwide are obsolete, unwanted, or broken beyond repair every year, extracting gold can be a profitable activity for recyclers that know how ...
Circuit Board Materials. Many of the materials used to make circuit boards can be recovered and recycled. This includes metals and plastics. Circuit boards contain different precious metals such as gold, silver, palladium and occasionally platinum. All circuit boards contain base metals such as tin, lead, iron, zinc, copper, nickel and aluminum.
We buy circuit boards from any device and pay you for the precious metals (such as gold, platinum, silver, and palladium) found within them.We buy circuit boards from computers, cell phones, telecommunication equiptment, servers, military equiptment, car electronics and many other sources.
A printed circuit board (PCB) is typically made by attaching a copper sheet to a substrate board, sometimes on both sides. The manufacturer then creates the circuits by removing copper so that only the required copper traces remain. This is called a subtractive method, and there are also additive techniques, usually for multilayer PCBs.
