Answer:

The precious metal is found in almost all computer components--processors, motherboards, extension cards, memory DIMMs, and so on. Of course, the amounts used in each part are infinitesimal. But with the price of gold skyrocketing in recent years, it’s becoming more and more economically-viable to recover gold from old electronic and computer components than to mine it. That’s why specialized companies have sprung up to do just that.

Today, we're going to show you how we recovered the gold from old motherboards using do-it-yourself methods. Please note: The chemicals used in this demonstration are extremely dangerous, especially in the concentrations used. Therefore, we strongly discourage you from attempting to reproduce this experiment at home.

Gold Everywhere

Gold is found in numerous places on a motherboard: IDE connectors, PCI Express slot, PCI, AGP, ISA, and other ports, jumper pins, the processor socket, and DIMM (SIMM on older motherboards) slots.

All of these connectors are often covered with a fine layer of gold a few microns thick, deposited by flashing or plating.
