Gold refining - is it worthwhile to refine gold from cell phones, computers, circuit boards and other scrap

Is it worthwhile to recover gold from electronic products?
The most common waste materials containing gold are used electronic products. These products are designed to achieve certain performance and therefore use trace amounts of gold in certain parts. To re-extract this gold requires the use of hazardous chemicals, although these are readily available. However, you must have the expertise and the appropriate equipment to perform this operation.
The value of the gold you recover from electronics depends on two factors: the type of e-waste from which you will be extracting gold and whether you will be performing a large or small scale extraction process. If you intend to perform a large scale gold recovery from electronics, then yes, it is worthwhile. However, if it is a small scale gold recovery, then you will make a small profit. The process of physically dismantling gold from electronic devices and extracting it is not a walk in the park.
The amount of gold you can find on a computer, laptop or cell phone depends on the size and model of the particular gadget. However, it is estimated that about 1/5 of the gold in a computer is worth about $70. A laptop is estimated to have about 1/10th of the gold, worth about $30. A cell phone has almost 1/30th of the gold and is worth about $10.

How can gold be recovered from e-waste without toxic chemicals?
Extracting gold from e-waste is tricky, especially because it involves the use of hazardous chemicals. Therefore, it is recommended to let professionals handle the gold extraction process. However, what happens if you want to do it yourself without using these hazardous chemicals? Other techniques you can use to extract gold from electronics include: Using reverse plating methods or using weak acids (such as vinegar).
